3.3 System Working Environments Checking
3.3.1 Cleaning
The battery system has high voltage connectors. The clean condition will cause the isolation
characteristic of the system.
Before installation and system working must clean the dust and iron scurf to keep the
environments cleaning. And the environment must have certain anti-dust ability.
The system after long term running must check the humidity and dust cover or not. If heavy dust
cover with high humidity on the system should stop the system running and make clean specially
for the high voltage connectors.
Danger: the power cables and plugs still have high voltage DC power from serial connected
battery modules (battery module can’t be turned off), must be careful to handle the
Power Plugs.

28℃.
Caution: Out of the working temperature range may cause the battery reduces the cycle of life
even cause the battery system over / low temperature alarm or protection.
3.3.3 Cooling System
The room must be equipped with cooling system.
Caution: Out of the working temperature range may cause the battery reduces the cycle of life
even cause the battery system over / low temperature alarm or protection.
3.3.4 Heating System
The room must be equipped with heating system. If the environment is lower than 0℃, must turn
on the heating system at first.
Caution: Out of the working temperature range may cause the battery reduces the cycle of life
even cause the battery system over / low temperature alarm or protection.
3.3.5 Fire-extinguisher System

3.6 Cables connection
3.6.1 Pay attention terms:
Danger: The battery system is high voltage DC system. Must make sure the grounding of the rack
is stable and reliable.
Danger: All the plugs and sockets of the power cables must be orange to orange and black to
black. Otherwise it will cause personal injury.
Danger: No short circuit or reserved connection of the battery system’s anode and cathode.
Caution: Wrong communication cables connection will cause the battery system failure.
Grounding
The PowerCube-M1 modules’ grounding is based on metal directly touch between
the module’s surface and rack’s surface. So it needn’t grounding cables at all. If
uses normal rack, remove the paint at the corresponding place.
Rack Grounding:
If there is a grounding metal frame outside the rack, for example, the metal angle
steel frame at the bottom of the container, the fix hole of the fix frame can be fixed
directly with the metal frame of the container. Then through the grounding of the container to
ensure reliable grounding.
If want to connect the ground cable, it can be connected to the M8 grounding bolt on the
frame base. Grounding cable must blAWG.

3.6.4 System turns on
Double check all the power cables and communication cables. Make sure the voltage of the
PCS is same level with the battery system. Check all the power switch of every battery system is
OFF.
Warning: MBMS must be turned on after all battery strings self-check finish.
(1) Check the UPS is turned on. And the UPS is power supplying.
(2) Switch the external power or PCS on, to sure all the power equipment can work normally.
(3) Turn on the 1st BMS (Battery Control Modules) of battery string:
The second BMS must be operated after the first battery string’s self-check is successful.
From 1st BMS to the last BMS Then turn on the battery strings on one by one from 1st BMS to the
last BMS.
Turn on the “POWER OUTPUT SWITCH”:
Turn on the “Power Switch”:
Caution: When the breaker is tripped off because the system has over current or short circuit,

17 / 32
19PIMV0802
must after 30min to turn on it again, otherwise may cause the breaker damage.
The battery string’s system will check itself, if work normal the battery string system will go
to self-check mode.
If the BMS and all battery modules are working normally, every status LED will lighting
green, that’s mean self-check are pass. Self-check will be finish within 5sec.
The BMS can’t receive communication from upper equipment because the
communication is off, the “STATUS”lamp will light red after 30sec. That doesn’t means
failure existing, it means this battery string is working normally.
Warning: If has failure during the self-check, must debug the failure then can start next step.
If the “STATUS”lamp shows red from beginning, it means has failure in the battery string,
the Power Relays in BMS will switch ON, must debug at first.
(4) Switch the MBMS on after all the BMS turn on successful:
And check MBMS is working. The “STATUS”lamp will light green.
The Power Relays in BMS will switch ON after 30 seconds, when the MBMS was turned ON.
The “STATUS”lamp of the BMS will light green;
When the voltage distance is smaller than the parameter, the battery string will do the
parallel operation.
When the MBMS was turned ON, the “STATUS”lamp of the BMS will light red, but it is
normal;
Note: If the MBMS can’t build communication with other equipment, the system can’t
work normally. External Power should communicate with battery system through LAN,
CAN or RS485. Otherwise maybe cause battery system work abnormal.
Caution: The whole Battery Energy Storage System (BESS) after installation or restart the system
when long time not in using should charge it to full at first.
3.6.5 System turns off
When failure or before service, must turn the battery system off:
(1) Turn off the switch between PCS and this battery string (PowerCube-M1), or turn off the power
switch of PCS, to make sure no current through this battery string.
(2) Turn off the “Power Output
Switch” of the BMS.
(3) Turn off the “Power Switch” of
the BMS.
