Working in a high voltage environment requires serious approch to
aviod human injuries and damage to equipment
Do not touch any circuitry during operation. Potentially lethal
voltages and currents are present
Avoid to touching the circuitry when covers are removed. The IED
contains electirc circuits which can be damaged if exposed to static
electricity. Lethal high voltage circuits are also exposed when covers
are removed
Using the isolated test pins when measuring signals in open circuitry.
Potentially lethal voltages and currents are present
Never connect or disconnect wire and/or connector to or from IED
during normal operation. Dangerous voltages and currents are
present. Operation may be interrupted and IED and measuring
circuitry may be damaged
Always connect the IED to protective earth regardless of the
operating conditions. Operating the IED without proper earthing may
damage both IED and measuring circuitry and may cause injuries in
case of an accident.
Do not disconnect the secondary connection of current transformer
without short-circuiting the transformer’s secondary winding.
Operating a current transformer with the secondary winding open will
cause a high voltage that may damage the transformer and may
cause injuries to humans.
Do not remove the screw from a powered IED or from an IED
connected to power circuitry. Potentially lethal voltages and currents
are present
Using the certified conductive bags to transport PCBs (modules).
Handling modules with a conductive wrist strap connected to
protective earth and on an antistatic surface. Electrostatic discharge
may cause damage to the module due to electronic circuits are
sensitive to this phenomenon
Do not connect live wires to the IED, internal circuitry may be
damaged
When replacing modules using a conductive wrist strap connected to
protective earth. Electrostatic discharge may damage the modules
and IED circuitry
When installing and commissioning, take care to avoid electrical
shock if accessing wiring and connection IEDs
Changing the setting value group will inevitably change the IEDs
operation. Be careful and check regulations before making the
change

mechanism for the day to day operation and even advanced use of the IED.
The keyboard, LCD and LEDs on the front of the IED are what constitute the
HMI. Troubleshooting, monitoring, setting and configuring are all possible via
this interface. Through the screens and menu elements available, as well as
the keypad, the user is able to navigate throughout the menu structure and
move from screen to screen.
The IED is unpacked and visually checked. The connection to the protection
system has to be checked in order to verify that the installation is successful.
The settings for each function must be calculated before the commissioning
task. The functions setting menu have been listed in detail so that the user
can find and change the required settings directly and correctly. For the
different application, the IED can be performed conveniently through
switching the setting group.
For the functions included in the IED can be tested by users, the testing
procedure have been listed as reference to verify that protection function
operate correctly.
After the IED is in service, some checking items also need to be done for
maintenance in order to ensure that the IED is in good condition during
operation, some suggestions have been preset as reference and the user can
perform some other checking items according to the relevant regulations.

3.1.8 RS232 port
RS232 serial port is located on front panel, the software tool in PC can be
connected with the IED via this port to make setting, testing and cofiguration,
etc.
3.2 Connecting to protective earth
Connect the earthing screw on the rear panel to the nearest protective
earthing point in the cubicle. The protective earth cables should be green or
yellow conductors with cross-sectional area 2.5mm2 according to electrical
regulations and electrical standards requirement.
The cubicle must be properly connected to station earthing system, using the
conductor with cross-sectional area of at least 4mm2.
3.3 Connecting the power supply module
The wiring from the cubicle terminal block to the IED terminals must be
connected in accordance with the established guidelines for this type of IED.
The wires from binary inputs and outputs and the auxiliary power supply must
be routed separated from the current transformer cables between the terminal
blocks of the cubicle and the IEDs connections.
3.4 Connecting to CT and VT circuits
CT and VT are connected to the analogue input module on the rear side of
the IED.
Using solid conductor with cross-sectional 2.5-6mm2 (AWG14-10) or stranded
conductor with cross-sectional 2.5-4mm2 (AWG14-12). The screws used for
fixation conductor should be tightened.
3.5 Connecting the binary inputs and outputs
Auxiliary power supply and binary input and output signals are connected
using female connectors. Signal wires are connected to a female connector,
which is then plugged into the corresponding male connector, located at the
Chapter 3 Installing IED
28
rear of the IED.
Procedure:
1. Connect signals to the female connector
All wiring to the female connector should be done before it is plugged into
the male part and screwed to the case. The conductors can be of rigid
type (solid, stranded) or of flexible type.
The female connectors accept conductors with a cross section area of
0.2-1.5 mm2 (AWG 24-15). If two conductors are used in the same
terminal, the maximum permissible cross section area is 0.2-0.8 mm2
(AWG 24-18, each conductor corresponding to one cross section area).
If two conductors, each with area 1.5 mm2 (AWG 15) need to be
connected to the same terminal, a ferrule must be used to combine the
two conductors, no soldering is needed.
Press the locking button by screwdriver to insert the wiring with ferrule
into the connector, move away the screwdriver after the ferrule has been
inserted into the connector completely to lock the wiring tightly. The follow
picture illustrate this process.
Figure 13 Connection illustration without inserting the connector
Chapter 3 Installing IED
29
Figure 14 Connection illustration with inserting the connector
2. Plug the connector to the corresponding back-side mounted male
connector
3. Lock the connector by fastening the lock screws
3.6 Making the screen connection
When using screened cables always make sure screens are earthed and
connected according to applicable engineering methods. This may include
checking for appropriate earth points near the IED, for instance, in the cubicle
and/or near the source of measuring. Ensure that earth connections are
made with short conductors of an adequate cross section, at least 6 mm2
(AWG10) for single screen connections.
3.7 Optical connections
This port is used to transmit the binary data between IEDs, there are two
optical ports at the rear side of CPU moduel, Figure 10 and Figure 11, the
two ports works in redundancy communication mode.
Chapter 3 Installing IED
30
The fiber optical cables are very sensitive to handling. Do not bend
too sharply. If cable straps are used to fix the cables, apply with
loose fit. Always hold the connector, never the cable, when
connecting or disconnecting optical fibers. Do not twist, pull or bend
the fiber. Invisible damage may increase fiber attenuation thus
making communication impossible.
Strictly follow the instructions from manufacture for each type of
optical cables or connectors.
3.8 RS485 and RS232 ports connection
3.8.1 RS485 port connection
The RS485 interface is capable of half-duplex service with the signals A/A'
and B/B' to transmit signals.
The network topology of RS485 adopts bus type of terminal matched, do not
support ring or star network. Use the single and continuous channel as bus.
The terminating resistance is located on beginning and terminal of the bus
cable. The other ports do not need the terminating resistance.
As shown in Figure 8 and Figure 9, RS485 port located on the rear side of
communication module. The IED provides two electrical isolation RS485
ports, the two ports can work at the same time with IEC60870-5-103 protocol
supported.
3.8.2 RS232 port connection
One RS232 serial port is provided and located on front panel, which is used to
connect personal computer. The RS232 port adopts half-dupex
communication mode, usually which is connected with 9-pin D-subminiature
female connectors
Connection method: direction connection cable for serial port, the IED
terminal is pins and the PC termianl is female connector. The terminal of 2, 3,
4 and 5 is connected directly. As shown in the following picture:
Chapter 3 Installing IED
31
Figure 15 Example for serial port connection
The line 4 must be connected directly
3.9 Connecting the GPS
Mount the GPS antenna on the building roof or the place of visibility to all
direction is obtained, top of the antenna should be horizontal. Mount the
antenna to console and fix the console on the building roof with expansion
bolts. The turning radius should not be too small when laying the cables. The
length of antenna cables is designed strictly based on antenna gain, so, it is
not allowed to lengthen, shorten or add connectors that will affect signal
reception or can't receive any signals.
The principle for mounting GPS antenna is that the position is visible
completely to all directions in 360°, however, for some special conditions,
mount the antenna at the place with best visibility as far as possible.
The GPS port is located on the rear side of communication module, as shown
in Figure 8 and Figure 9, which can be connected with screened twist-pair
cable.

Chapter 6 IED testing
About this chapter
This chapter describes the method of hardware testing, such as
power supply, binary input and output, analog quantities and all
functions testing method and testing procedure.
Chapter 6 IED testing
52
1 Introduction
IED test requirements:
Setting value list
The correct IED setting value must have been set before the
testing can start.
Application configuration diagram
Terminal diagram
The terminal diagram and module arrangement diagram,
available in the Technical application manual, is a general
diagram of the IED. but note that the same diagram is not
always applicable to each specific delivery (especially for the
configuration of all the binary inputs and outputs). Therefore,
before testing, check that the available terminal diagram
corresponds to the IED.
Technical application maunal
The Technical application manual contains application and
functionality summaries, function block, logic diagram, input
and output signals, setting parameters and technical data
sorted per function.
The three-phase test equipment
The test equipment should be able to provide a three-phase
supply of voltages and currents. The magnitude of voltage and
current as well as the phase angle between voltage and
current must be variable. The voltages and currents from the
test equipment must be obtained from the same source and
they must have minimal harmonic content. If the test
equipment cannot indicate the phase angle, a separate
phase-angle measuring instrument is necessary.
Prepare the IED for test before testing a function. Consider the
logic diagram of the tested protection function when perform the
test. All included functions in the IED are tested according to the
corresponding test instrunctions in this chapter.
Chapter 6 IED testing
53
The response from a test can be viewed in different ways:
Binary output signals
Display value in HMI
All setting groups that are used should be tested.
The IED is designed for a maximum continuous current of
three times the rated current
Please observe the measuring accuracy of the IED, the
test equipment and angular accuracy for both of them
Chapter 6 IED testing
54
2 Points for attention during testing
Be familiar with the engineering drawings, engineering and
operation manual and technical application manual
Before testing, check that the short-circuited wire used to avoid
CT secondary circuit opening is connected correctly and firmly.
The short-circuited phenomenon of VT secondary circuit does
not exist
It is allowed to plug-in and pull out each module after the power
supply disconnection. Aviod AC current circuit opened when
plug in and pull out the modules
Keep cleaning and pay attention to dust prevention for each
module
Adoption the measure of the human body electrostatic
grounding prevention to make sure that the IED is not
damaged by hunam electrostatic
In principle, the electric iron can't be used in field, if the electric
iron need to be used for welding during testing, the welding
can be performed after the power disconnection or using the
electric iron with earthed wire
During testing, do not insert the module into the wrong position.
When plug in and pull out the module apply appropriate force
instead of overexerting to avoid pins bending or damage the
fastening components of module
Short-circuited or disconnected terminals temporarily for
checking, it should be recorded one by one and return to
original state after the testing is completed
Using the electronic devices (e.g. oscillograph, etc.) with AC
power supply to measure the circuit parameters, the case of
the device should be earthed in the same grounding with
protection IED cabinet
During testing, consider the safety measure between the IED
and other running equipment and the safety measure of
related circuit between external running equipment and the
IED
Chapter 6 IED testing
55
During testing, if the current magnitude that is input into IED is
large than three times of rated current, it should be noticed that
the time should not be too long
When energizing the IED in the first time, using multimeter to
check the power supply, the circuit of voltages and currents are
connected correcly to avoid short circuit or open circuit
Tighten all the screws of all terminals again for the new project
in order to prevent improper connection, and plug in and pull
out all the modules again to aovid the modules loosing result
from operation or installation
Chapter 6 IED testing
56
3 Preparing for test
3.1 Introduction
Please read the corresponding manuals that is provided by
manufacturer in detail before testing, try best to understand the
basic operation, protection principle and the relevant
capabilities. If have any questions in this procedure, please
inquire the field service engineer or the technical support
engineer of SiFang.
All checking should be done before energizing, inspection well
and no damage on the surface, all modules are inserted firmly,
the insulation of the power circuit are satisfied the specified
requirement.
Disconnect the external circuit before testing to avoid safety
accident or injuries to the human
If the modules are needed to be plugged in or pulled out, make
sure that the power is disconnected, and the measure of
prevention electrostatic should be done in order to avoid the
damage to module or performance degradation
The opened or short-circuited terminal temporarily should be
recorded in detail in order to return to original state reliably
3.2 Connecting test equipment to IED
Before testing, connect the test equipment according to the IED
specific connection diagram. Pay special attention to the correct
connection of the input and output current terminals. Check that the
input and output logical signals in the logic diagram for the function
under test are connected to the corresponding binary inputs and
outputs of the IED. The testing connection diagram is shown in
Figure 16.
The user must verify that the connections are correct and the
analog signals are measured correctly after connection completed.

with five times in short time, checking the tolerance of date and
time is within the permissible range.
9.4 Checking the voltage and current
Inject system currents (load current must be larger than 0.08In) and
voltages into the IED, and then check whether the magnitude,
phase angle, polarity and phase sequence of each measuring
analog value are correct or not.
9.5 Checking the setting group
Make sure the active setting group is correct.
9.6 Checking the setting
Checking the settings one by one of each group which are possibly
Chapter 6 IED testing
91
used in the actual operation modes.
9.7 Checking the binary input
Check the state of all binary inputs. Particularly ensure that the IED
is not in test mode, meaning there is not a hand type icon displayed
at the upright corner of the LCD.
9.8 Checking the normal operation mode
9.8.1 Trip and close test with the circuit breaker
9.8.1.1 Switching the circuit breaker state by local command
Trip and close the circuit breaker, the corresponding feedback state
of circuit breaker injected via binary inputs should be read out and
compared with the actual state of circuit breaker, the displayed
state should be in accordance with the actual state.
9.8.1.2 Switching the circuit breaker state from remote control
center
If the IED is connected to a remote substation via SCADA, the
corresponding switching tests may also be checked from the
substation.
9.9 Put into operation
If all the checking items described above and the other checking
items need to be performed according to the site condition have
been checked and correct, the IED can be put into operation.
