1 ECC500 Overview 1.1 Positioning

The ECC500 is a cross-platform monitoring product, in which a main control module works

with several expansion boards. The ECC500 monitors loads, power supplies, storage batteries,

environments, and the temperature control unit (TCU) to ensure system reliability and

operation security. It also schedules site energy as required, saving energy and reducing site

operating expense (OPEX).

Figure 1-1 ECC500

1.2 Benefits

Battery Management The ECC500 manages the voltage of boost or floating charge, voltage adjustment,

temperature compensation and current limit coefficient based on the energy usage and

system status to ensure the proper running of storage batteries.

The ECC500 calculates remaining storage battery capacity, duration for battery charge

and discharge per day, and perform operations based on the calculation results.

Management on Intelligent Components and Loads The ECC500 locally and remotely manages intelligent components for energy and

environment monitoring, such as power supply unit (PSU).

The ECC500 identifies and stores electronic labels of intelligent southbound components

and its local electronic label.

The ECC500 controls the disconnection order of loads based on the subrack connected.





2

Monitors three-phase AC input voltages, currents, and power by using an intelligent

electric meterYD3060-1.

Supports load low voltage disconnection (LLVD) and battery low voltage disconnection

(BLVD).

Communication The ECC500 reports site information including alarms, statistics, and current status to

northbound equipment over out-band transmission. It also receives control and

configuration information from northbound equipment and performs operations

accordingly such as opening or closing dry contacts or controlling southbound

equipment.

The ECC500 communicates with southbound equipment over all-purpose master/slave

protocols, and Modbus to collect required data for other modules. It also sends control

and configuration commands to southbound equipment for battery connection control.

Over northbound communication, applications of the ECC500 and northbound

equipment can be loaded online and their electronic labels can be queried.

Statistics Collection and Storage The ECC500 collects performance data, such as the generated energy of mains,

remaining battery electricity, and load power consumption, and stores the data every 5

minutes, per hour, per day, per month or per year.

The ECC500 locally stores, queries, and monitors southbound components and sensors.

The ECC500 exports historical data over the web user interface (WebUI) or Network

Ecosystem (NetEco).

User-friendly Interface Running parameters of monitored equipment such as the alternating current (AC), direct

current (DC), battery status, and control parameters are displayed on the liquid crystal

display (LCD), WebUI or NetEco in real time.

Site setup and network connection parameters of the site and NetEco such as IP

addresses and access point names (APNs) can be set over the LCD to implement

laptop-free deployment.

TheLCD/WEB allows you to obtain real-time information, alarms, and statistics from

corresponding tab pages and send control commands.

Over the WebUI or NetEco, historical performance data can be exported, and the

ECC500 can be remotely upgraded.

Alarm Determination and Management If a fault occurs, an alarm is generated and displayed on the LCD, WebUI, and NetEco.

If the ECC500 determines that an alarm is generated, it turns on the alarm indicator,

displays the alarm information on the LCD and WebUI, and reports the alarm to the

NetEco.

If the ECC500 determines that an alarm is cleared, it turns off the alarm indicator and

notifies the NetEco of the alarm clearance, and the alarm information on the LCD and

WebUI disappears.

A maximum of 500 active alarms can be displayed, 1000 historical alarms can be saved,

and cleared alarms can be queried on the LCD.





3

Dry Contact Input and Output

Allows alarms to be generated over dry contact outputs.

Allows one or more alarms to be generated over the same dry contact output.

Provides nine dry contacts.

Log Management

The ECC500 records operation logs in detail, These logs can be viewed and downloaded over

the WebUI.

1.3 Typical Application Scenarios The ECC500 transmits data out-of-band modes.

The ECC500 supports out-of-band communication by GPRS or IP. If the ECC500

communicates by GPRS, it must be configured with a GPRS module. GPRS stands

for General Packet Radio Service.

The NetEco is configured based on customer requirements.

Figure 1-2 Position of the ECC500 on the network





4

The temperature control units that access over dry contacts include natural-ventilation units and

TECs.

The equipment monitored by the ECC500 should be selected based on site requirements.

Safety Information Exercise caution when moving the shelf while wearing electro static discharge (ESD)

gloves.

Protect yourself from falling down.

Tools

Ensure that a Phillips screwdriver (M3x100 or M6x200) and a flat-head screwdriver (M2x100

or M6x200) are available.

3.2 Installation

The ECC500 can be installed in 19 inch cabinets, as shown in Figure 3-1.

Installation personnel must be trained to perform operations correctly and safely.

CAUTION





16

Figure 3-1 ECC500 installation scenario

To install the ECC500, perform the following steps:

Step 1 Install mounting ears on the ECC500.

Step 2 Install floating nuts on the cabinet.

Step 3 Hold the mounting ears of the ECC500, and place the ECC500 on the guide rails corresponding to its installation position on the rack.

Step 4 Push the ECC500 inside the cabinet to ensure that the mounting ears are level with the columns in the cabinet.

Step 5 Pre-tighten each screw in the four mounting holes of the mounting ears using an M6 Phillips screwdriver.

3.3 Cable Connection

3.3.1 Connection Sketch

The cable connection of the ECC500 is chosen on the basis of site requirements.

The cables are divided into the following types: ground cables, RJ45 communications cables,

dry contact signal cables, GPRS antennas (including the SIM card) and DC cables.

Ground Cables

When the ECC500 is installed, connect the ground cables, as shown in Figure 3-2.

CAUTION





17

Figure 3-2 Ground cables

Communications Cables to RJ45 ports

The RJ45 terminal is used in the RS485/232 serial port and the Ethernet port. Figure 3-3

shows the RJ45 port pins.

Figure 3-3 RJ45 port pins

Plug one end of the telecom cable into the communication, and plug the other end of the

telecom cable into the serial port of corresponding communication.

Dry Contact Signal Cables

Press the plate of the dry contact lightly using the flat-head screwdriver, and then plug the

signal cable of the dry contact into the small holes under the plates. Figure 3-4 shows the

connection of the dry contact signal cable.

Figure 3-4 Installing a dry contact signal cable





18

GPRS Antenna and SIM Card

The Global System for Mobile Communications (GSM) antenna connector is fastened to the

RF port on the GPRS module. The antenna is installed in an unshielded place to ensure that

signals are not shielded. If the GPRS antenna is more than 3 m (9.84 in.), lightning protection must be considered.

If the mounting bracket of the GSM antenna has a plastic shell, remove it before installing the

GSM antenna to ensure that the magnet sticks to the unit.

Figure 3-5 GSM antenna installation

If the GPRS function of the ECC500 is required, take out the GRPS module. Then insert the

SIM card. Figure 3-6 shows the installation and removal of the SIM card.

5.2 Parts Replacement

This section describes how to replace the faulty modules of the ECC500.

NOTE





46

Personnel must be trained to perform operations correctly and safely.

Operators must wear ESD gloves.

When replacing components, power off the ECC500, remove DC cables, and attach labels

to the cables.

Module Replacement

To replace a module in the ECC500, perform the following steps:

Step 1 Remove the signal cables from old module. Insulate the cables in time and stamp labels.

Step 2 Loosen the captive screws on the old module anti-clockwise using the M3 screwdriver.

Step 3 Pull out the old module by grasping the handle with both hands, as shown in Figure 5-1.

Step 4 Grasp the handles of the new module, and insert the module into the corresponding slot in the ECC500 subrack.

Step 5 Push the new module until its front panel is level with that of the ECC500 subrack.

Step 6 Fold the handle.

Step 7 Tighten the captive screws using the M3 screwdriver, as shown in Figure 5-2.

Step 8 Connect the cables to the module according to the labels on the cables.
