Removing/Installing the CSU and Rectifiers
Warnings/Cautions Remove watches, bracelets, rings or other conductive objects before the operation. Wear special gloves for protection against electrostatic hazards. Failure to comply can result in damage to equipment. Never set heavy objects on top of the cabinet. Failure to comply can result in damage to equipment.

(1) Batteries used in the system should be of the same type. Old and new batteries must not be used together. (2) Battery packs should not be short-circuited in any way during the operation. Always use insulated tools when making electrical connections and always ensure that all connection terminals and unnecessarily exposed metal parts are fully insulated. Failure to comply can result in damage to equipment. The system has high leakage current, thus it must be properly grounded before power-on. The grounding cable should be connected to the nearest grounding terminal, and the cable length cannot be greater than 30 m. Cable requirements:
Be aware of jamming!
Removing the Rectifier 1
Installing the Rectifier
Loosen the captive screws.
2
Cable diameter: The diameter of a cable should match the load capacity.

Locked
Cable color: When using cables in non-standard colors, use black cables and mark them using heat-shrinkable tubing or insulated tape in corresponding colors to avoid errors. If local regulations have different requirements for cable colors, always follow the local regulations. Failure to comply can result in damage to equipment. Cable turning radius: At a corner of a cabling route, the turning radius should be 10 times equal to or greater than the cable diameter to avoid short circuits due to the cable tube damage caused by the turning radius being too small. Be aware of jamming!

AC Input Mode
AC Input Circuit Breaker
AC Input Cables to Be Connected
1
Choose Proper DC Output Branches.
The system provides two battery circuit breakers. Two battery packs can be installed inside the W201 cabinet.
Choose circuit breakers of proper capacity. The load capacity connected to each DC output branch cannot exceed the circuit breaker capacity. Certain redundancy should be reserved to prevent interruption of power supply to the loads due to the circuit breaker trip.
110V - 127V ~ 3W+N+PE
63A/3P*1 MCB
L1, L2, L3, N, PE
For example, if the capacity of a circuit breaker is 32 A, it can connect a load with the peak capacity of no more than 25 A.
110V - 127V ~ 2W+N+PE
80A/2P*1 MCB
L1, L2, N, PE
Divide loads into primary loads and secondary loads.
220V - 240V ~ 3W+N+PE
63A/3P*1 MCB
L1, L2, L3, N, PE
Connect primary loads to the LLVD2/BLVD branches and secondary loads to the LLVD1 branches.
220V - 240V ~ 1W+N+PE
100A/1P*1 MCB
L, N, PE
Caution:
Battery Placement Requirements Enough space should be reserved around each battery and a minimum distance of 10 mm is required. If the spacing requirement (no less than 10 mm as shown) is satisfied, the batteries should be placed on the right and rear sides in the cabinet to avoid short circuit caused by friction of the door lock.

Installing Battery Temperature Sensors
Based on the actual requirements, connect supervision cables to relays and interfaces on the Signal Interface Board (SIB).
The battery temperature detection cables have been laid in the chassis and one end (with two-pin plug) of the cable has been connected to the battery temperature detection interface on the SIB. The other end is the temperature sensor, which needs to be installed on site.
The SIB provides input & output relays, communication interfaces, battery temperature sampling interfaces, and environmental detection interfaces.

Operating the CSU
Normal Shutdown
The software version of the W201 system with 110V - 127V AC input is V1.0G. The software version of the W201 system with 220V - 240V AC input is V1.0. Perform the following operations in the CSU. For details, refer to the ZXDU CSU500 (SV1.0/SV1.0G) Centralized Supervision Unit Quick Reference.
Manual Power Recovery
Caution The system shutdown will cause power supply interruption to the loads connected. Do not shut down the system without permission. Failure to comply can result in loss of traffic or damage to equipment.
Steps: When the system is used for the first time, the system and battery parameters must be set properly according to the actual configuration on site.
1. To ensure that the system is free of loads, remove power from all loads or switch the loads to another power supply system. 2. Set all DC output circuit breakers to OFF position.
2. (Optional) Set output relays and levels for alarms. Users can set the output relay and level for each alarm and record the setting in the “Alarm List”. 3. (Optional) Set attributes for input relays. Users can set the alarm name and alarm state for each input relay. The default alarm state of each input relay is “Close”.
Starting the Rectifiers
3. Set all battery circuit breakers to OFF position. 4. Set W201 AC input circuit breaker to OFF position. 5. Set the AC output circuit breaker (in the AC power distribution box) to OFF position to remove power from the W201 system.
Caution The emergency shutdown should only be performed during an emergency. Failure to comply can result in loss of traffic or damage to equipment.
Steps:
Steps: 1. Install the rectifiers one by one.
2. Set all battery circuit breakers to OFF position.

Startup High current leakage exists during the system operation. The system must be well grounded before power-on. Failure to comply can result in damage to equipment or operation failure.
Steps:
Prerequisites:
1. Ensure that power switches of the load equipment are set to OFF position. 2. Set the DC output circuit breakers connected to the load equipment to ON position.
Before startup, ensure that the system has been properly installed and configured and all required tests has passed.
3. Use a multimeter to check DC power supply for one of the loads.
Steps:
Red probe (+): Touching the +/GND connection terminal of the load Black probe (-): Touching the -48 V connection terminal of the load 4. Verify that the multimeter indicates a value of 42 V to 58 V. 5. After the test has passed for all loads, set power switches of the load equipment to ON position.

2. Because the CSU is ineffective and cannot limit the output current of the rectifiers, to avoid high-current charging to the batteries, calculate the quantity of the rectifiers that need to operate according to the total load power and the power required by the battery charging. Deactivate the excessive rectifiers according to the calculation result. (Note: Keep phase balance.)
Note:
2. Set device addresses for the rectifiers one by one.

1. Press the LLVD1 ON button to connect the LLVD1 branch to the system. The LLVD1 loads are powered on.
Quantity of required = rectifiers
Caution
1. Set the AC output circuit breaker (in the AC power distribution box) to OFF position to remove power from the W201 system.
Refer to the “Setting the Device Addr. of a Rectifier” section in the ZXDU CSU500 (SV1.0/SV1.0G) Centralized Supervision Unit Quick Reference.
Steps:
3. Press the LLVD2/BLVD ON button to connect the battery branch to the system and charge the batteries. Omit this step if the LLVD2/BLVD disconnection has not occurred.
Emergency Shutdown
For the W201 system with 110V - 127V AC input (software version: V1.0G), manually enable the CSU to count operating rectifiers after removing a rectifier from the cabinet. Failure to comply can result in the SMR Comm.Fail (SMR communication failure) alarm. For the W201 system with 220V - 240V AC input (software version: V1.0), set the SMR Quantity parameter according to actual number of operating rectifiers.
Note: The disconnection mode (LLVD1, LLVD2, BLVD) is subject to the contract.
Steps:
1. Set system and battery parameters.
When the system is in the state of LLVD1 or LLVD2/BLVD disconnection, if the CSU is ineffective despite that the AC recovers and the rectifiers output DC power, users can perform the following steps to manually connect the disconnected branch(es).
1. Set the AC output circuit breaker (in the AC power distribution box) to ON position to apply power to the W201 system.
Manually Enabling the CSU to Count Operating Rectifiers (for software V1.0G only) When a new rectifier is installed, the CSU can automatically count operating rectifiers. When a rectifier is removed from the cabinet, select SMR Ctrl. > CAN Dev.Stat. to manually enable the CSU to count operating rectifiers. Otherwise, the SMR Comm.Fail (SMR communication failure) alarm will be activated.

2. Set AC input circuit breaker to ON position.
