To connect the RS485 communication bus:
1. Remove the inverter cover as described in
Removing the Inverter Cover
on page 86.
2. Remove the seal from one of the openings in communication gland #2 and insert

5.
Insert the wire ends into the G, A and B pins shown above. Use Four- or six-wire
twisted pair cable for this connection.
You can use any color wire for each of the A, B and G connections, as long as:
The same color wire is used for all A pins the same color for all B pins and
the same color for all G pins
The wire for G is not from the same twisted pair as A or B.
6.
For creating an RS485 bus - connect all B, A and G pins in all inverters. The following
