The supply voltage may deviate from the rated supply voltage specified in the table by -15% to +10%.
The breaking capacity of the auxiliary switch 3SV92 is shown on the following tables:
Closing solenoid (Y9) The closing solenoid 3AY1510 closes the circuit-breaker. After completion of a closingoperation, the closing solenoid is de-energised internally. It is available for AC or DCvoltage. Power consumption: 140 W or 140 VA.
Shunt releases The shunt releases are used for automatic and deliberate tripping of circuit-breakers.They are designed for connection to external voltage (DC or AC voltage). In special
cases, for deliberate tripping, they can also be connected to a voltage transformer.
Shunt releases based on two different principles are used: The shunt release (Y1) 3AY1510 is used as standard in the basic circuit-breaker
version. With this design, the circuit-breaker is opened electrically. Powerconsumption: 140 W or. 140 VA.
The shunt release (Y2) 3AX1101 with energy store is fitted if more than one shuntrelease is required. With this design, the electrical opening command is transferredmagnetically and thus, the circuit-breaker is opened. Power consumption: 70 W or50 VA.
Undervoltage release Undervoltage releases are tripped automatically through an electromagnet or
deliberately. The deliberate tripping of the undervoltage release generally takes place viaa NC contact in the tripping circuit or via a NO contact by short-circuiting the magnet coil.With this type of tripping, the short-circuit current is limited by the built-in resistors.Power consumption: 20 W or 20 VA.
Circuit-breaker trippingsignal
When the circuit-breaker is tripped by a release, there is a signal. If the circuit-breaker istripped deliberately with the mechanical pushbutton, this signal is suppressed.
C.t-operated release (Y6) The c.t.-operated release 3AX1104 is adequate for a tripping pulse of " 0.1 Ws inconnection with adequate protection systems. It is used if auxiliary voltage is missing,tripping via protection relay.

11.5 Disposal
SIMOPRIME switchgear is an environmentally compatible product.
All metal plates are powder-coated with resistant epoxy resin material.
The switchgear materials should be recycled if possible. The switchgear can be disposedof in an environment-compatible manner in compliance with existing legislation.
The components of the switchgear can be recycled as mixed scrap; however,dismantling as far as possible into sorted scrap with a residual mixed-scrap portion is themore environmentally compatible way.
Electronic scrap has to be disposed of in accordance with the existing regulations.
The switchgear consists of the following materials: Sheet-steel, powder coated Copper Aluminium Cast resin Fibre-reinforced plastics Rubber materials Ceramic materials Lubricants Bolts, washers, nuts, rivets
As delivered by Siemens, the switchgear does not contain hazardous materials as perthe Hazardous Material Regulations applicable in the Federal Republic of Germany. Inother countries, the locally applicable regulations must be followed.
Should you require further information, please contact your regional Siemensrepresentative.

The door to the switching-device compartment can only be opened and the truck canonly be moved if the switching-device truck is in test position and the truck is
interlocked.
! Rack the switching-device truck to test position.
! Interlock the switching-device truck.

888-3013.9 * OPERATING INSTRUCTIONS Simoprime * Revision 02 49
Operation ! Unlock the switching-device truck. To do this, turn the lateral fixing levers 90
outside.
! Move the switching-device truck to the front and out of the panel.
! Fold-in the ramps.
! Close the door to the switching-device compartment.
21 Verification of safe isolation from supply (LRM system)
The panels can be equipped with voltage detection systems.
Use voltage indicators according to IEC 78/183/CDV only.
The perfect function of the voltage indicator must have been verified: with a test unit according to IEC 78/183/CDV on live equipment
The function of the coupling section must have been checked according to: IEC 78/183/CDV
! Plug voltage indicator in all three phases L1, L2, L3 of the interface.
! If the indicator does not flash or light up in any of the three phases, the phases areisolated from supply.
DANGER!
Risk of injury by the switching-device truck falling over.
! Only qualified personnel is permitted to move the switching-device truck.
! Make sure that the switching-device truck does not slip off the ramps.
! Pull the switching-device truck slowly to the front and out of the panel.
! Support the switching-device truck with one feet on the bottom of the truck ! while moving the truck into the panel.

Operation
50 Revision 02 * OPERATING INSTRUCTIONS Simoprime * 888-3013.9
22 Manual operation of shutters
The feeder and busbar shutters can be opened individually. When one shutter is opened,the mechanism of the other one can be locked. If both shutters have to be opened at thesame time, locking the respective shutter mechanism is omitted in the following workoperations.
Opening the feeder shutter(lower shutter)
! Padlock the busbar shutter mechanism on the left side of the panel .
! Apply operating lever on shutter mechanism on right side of panel.
! Push operating lever down.
DANGER!
High voltage! Danger! If the busbars in the busbar compartment and the cable or barconnections in the connection compartment have not been isolated, the contacts arelive at operating voltage.
! Isolate the busbars in the busbar compartment and the cable and bar connectionsin the connection compartment before opening the shutters.
! Observe the 5 Safety Rules .
! Verify safe isolation from supply see Page 49, "Verification of safe isolation fromsupply (LRM system)".

888-3013.9 * OPERATING INSTRUCTIONS Simoprime * Revision 02 51
Operation ! Lock operating lever in lower position with fixing screw.
! Feeder shutter is open.
! Rack the switching-device truck to TEST position.
! Open the door to the switching-device compartment.
! Pull the switching-device truck out of the panel over the ramps.
Closing the feeder shutter ! Hold operating lever in lower position.
! Undo fixing screw.
! Move operating lever upwards.! Shutters close automatically.
! Move the switching-device truck into the panel over the ramp.
!Close the door to the switching-device compartment
Opening and closing thebusbar shutter (upper
shutter)
The busbar shutter is opened and closed in the same way as the feeder shutter. Performthe same work operations as for operating the feeder shutter on the other side of thepanel.
! Padlock the feeder shutter mechanism on the right side of the panel.
! Operate the busbar shutter on the left side of the panel.
23 Replacing high-voltage fuses
The fuses are mounted at the vacuum contactor on the truck.
!Open the door to the switching-device compartment see Page 34, "".
! Pull the truck out of the panel over the ramps see Page 48, "".
ATTENTION!
The switchgear can be damaged.
! Replace HV HRC fuse links only.
! During replacement, take care to use HV HRC fuse links with the same ratings andfrom the same manufacturer.

Operation
52 Revision 02 * OPERATING INSTRUCTIONS Simoprime * 888-3013.9
Removing fuse links ! Remove defective fuses. To do this, pull the fuse out of the contact spring first at thetop and then at the bottom.
Inserting fuse links !
Insert new fuses so that the striker pin is at the top. To do this, insert the fuse first inthe lower contact spring and then in the upper contact spring.
! Reset the fuse tripping contact (push the operating rod briefly to the back).
! Move the truck into the panel over the ramps.
! Close the door to the switching-device compartment.
DANGER!
Risk of burning due to hot fuses.
! Do not touch fuses, check temperature first.
!Let hot fuses to cool down.
