7 Communication Cables Connection
7.1 Overview Of All Communication Cables Connection Methods
All communication cables will be done on the communication broad which
is in the wiring box.
Therefore this section will introduce the steps and requirements for all
communication cables connections.

Step1: Make sure the DC switch is in “OFF” position before removing the
communication cover.
Step2: Remove the 1 cover screws, then remove the communication broad.

Operator should use the standard size conduit which must fit with the holes on the
bottom of the inverter. Conduit fittings need to be water tight.
Once the conduit and fittings are installed, wires will need to go through the
conduit and be locked into the corresponding terminals (refer to next section in
details).
It is recommended that all communication cables should be connected through
two conduits from the bottom right side of the inverter.
Note for specific wiring requirements, refer to Section 6.1.
For specific wire size and torques, refer to Section 6.1.
