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 activated
(switch S2 -120 TERM in ON position). See Fig
Each AURORA is provided with default address two (2), and with the S2 switch in OFF
position.
In order to ensure optimum communication on the RS485 line, Power-One recommends
connecting the PVI-USB-RS485_232 adaptor between the first unit of the daisy chain
and the computer. See Fig. 26 for details. (RS485-USB Convertor)
