RJ45 connectors
Alternatively, the RS485 serial connection of the inverters, whether as single units
or a daisy chain, can be performed by means of RJ45 connectors (see Fig. 25)
The wiring is must routed through the holes, which are closed by airtight plugs and
are located on the bottom of the inverter (see Fig
.
24). Input wiring passes through
one hole, and is assembled to one of the RJ45 connectors. The output wiring exits
from the other RJ45 connector through the other hole, and extends towards the next
unit.
It does not matter whether the two wirings are connected to connector no.1 or no.2,
insofar as the signals are connected in parallel all the same.
