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
The wiring must be routed through the holes closed with airtight plugs, located on the
bottom of the inverter (see Fig
assembled to one of the RJ45 connectors; output wiring passes through the other hole
and is assembled to the RJ45 connector of the next unit.
It does not matter whether it is no.1 or no.2 insofar as, being connected in parallel, the
signals are the same.
6.1.3

Daisy chain

The RS-485 terminal block or RJ45 connectors can be used to connect a single
AURORA inverter or multiple inverters, connected in a daisy chain. The maximum
number of inverters that may be connection in a daisy chain is 62. The recommended
maximum length of this chain is 1000 meters.
If several inverters are connected in a daisy chain, it will be necessary to assign an
address to each. See paragraph 5.5.6.1 for information on changing addresses.
Furthermore, the last inverter in the chain must have the line termination contact of the
activated line (switch S2 -120Ω TERM in ON position) see Fig.
Each AURORA is provided with default address two (2) and with the S2 switch in the
OFF position.
