Daisy Chain
The RS-485 terminal block or RJ45 connectors can be used to connect a single Aurora
inverter or multiple Aurora inverters connected in a daisy chain. The maximum
number of inverters that can be connected in a daisy chain is 64. The recommended
maximum length of this chain is 1,200 metres.
In a case where multiple inverters are connected in a daisy chain, it is necessary to
assign an address to each unit. Refer to paragraph 5.5.6.1 for instructions on how to
change addresses.
In addition, the last inverter of the chain must have line termination contact active (S2
switch -120Ω TERM set to ON). See Fig. 27.
Every AURORA device is supplied with default address two (2) and with the S1
switch in the OFF position.
