WECO 5K3-XP RACK LV-EMEA
14
Version 11/11/2021
ATTENTION:
The Battery Module weighs 126.3 lb (57.3 kg) and must be installed with the help of a mechanical lift, and/or with at
least two people equipped with suitable suction cups for mechanical lifting or lifting straps.
1.4 Out of the Box Pre-Operational Check
Attention: Do not make any connection to the Battery Module until you have thoroughly read and understood this entire manual.
Attention:
The Low Voltage Battery Module has safety mechanical contactor to isolate positive terminals, there is no physical circuit breaker on the
negative terminal.
The BMS POWER SWITCH is not a safety isolator as it is designed just to enable and disable the power supply of the BMS (5 Volts power
supply).
Turing off the BMS POWER SWITCH does not imply that the safety contactor has open the circuit.
The BMS POWER SWITCH is a mechanical ON/OFF switch that enables/disables the power supply of the BMS only
Set the Power Switch to ON (1) to start activation of the battery power supply, Set to OFF (0) to shut down completely.
There is an RS232 Operator Port which will allow you to check all parameters of the Battery Module. Full instructions on how to interface to
the RS232 port can be found in this manual.
The RS232 Port is enabled when the BMS Power Switch is turned ON (1)
Attention:
The 5K3 LV RACK module can only be connected in parallel.
Make sure the voltage of each module that is going to compose the tower is consistent with the rest of the modules.
A voltage difference between modules will cause an improper charge/discharge process
The GREEN LED light only shows that the BMS is enabled, does not indicate any circuit matching between other modules
