RJ12 connectors

As an alternative to RS485 serial connection, whether using single units or a daisy
chain, inverter connection can be performed by means of RJ12 connectors (see Fig.
24).
Wiring is again routed through the holes located at the bottom of the Inverter which
are blanked with waterproof plugs (see Fig. 23). Input wiring passes through one hole
and is to be assembled to one of the RJ12 connectors; it does not matter whether it is
no. 1 or no. 2 since signals are the same considering that they are connected in parallel.
Output wiring goes out from the other RJ12 connector through the other hole and
extends to the next unit.
