5.2 Battery BMS to PCS communication connection
The communication cable can be routed with DC power cables. Take care that the communication cable is
routed through the inter-cabinet coupler so that there is no stress or tension on the terminations. This cable is
terminated with RJ-50, 10-pin connectors.

6 System Electrical Wiring
Note:
This product is capable of providing utility interactive and islanded back up power, and can be
AC coupled to a utility interactive photovoltaic inverter. Wiring methods must be in accordance with
local electrical codes. The installer is responsible for ensuring that over-current protection is installed
and sized appropriately for the AC grid and off-grid output circuits, in accordance with the AS/NSZ electrical code.
All field wiring connections to the battery system are at the PCS
cabinet only. The diagram (left) indicates the knockout locations for
conduit entry into the PCS; categorized as AC power and signal level
circuits.
IMPORTANT!
Drilling holes anywhere in the battery or
PCS cabinet renders the warranty null and void.
Use the
knockouts provided at the bottom face of the PCS cabinet only! Do
not drill holes anywhere in the battery system. Use conduit fitting
reducers, if applicable.
