Power And Communication Cable Connection - Pylontech PowerCube-X1 Operation Manual

Caution: Wrong communication cables connection will cause the battery system failure.
Grounding
The PowerCube-X1/X2 modules' grounding is based on metal directly touch
between the module's surface and rack's surface. So it don`t need grounding
cables at all. If uses normal rack, it should remove the paint at the corresponding
grounding point.
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.
The cable shall be copper with yellow-green color.
If want to connect the ground cable, it can be connected to the M8 grounding bolt on the frame
base. Grounding cable must ≥10AWG.

If there are more than 1 rack of PowerCube-X1/X2, there will require a MBMS on the top
which aggregate information from all the BMS and communicate with inverter/PCS.
