6.1.1 RS-485 serial port
The RS-485 serial port uses a three-wire cable: two for signals, and a third for
ground connection. The cable should be passed through the holes located on the
bottom of the inverter, closed with airtight plugs (see Fig

The supplied cable gland must be installed into the appropriate hole.
Fig. 24 - Cable routing for RS-485 connection
For ease of installation, the inverter is provided with two holes to differentiate the
input cable route from the output cable route when several units are connected in a
daisy chain as described below.
Once the cables have been passed through the cable gland, they are connected
inside the unit to the RS-485 terminal blocks, which can be accessed by removing
the front cover. Refer to par. for information on correct front cover removal and
reassembly.
The signal wires must be connected to the +T/R and –T/R terminals
