6.1.3 Daisy chain
Terminal block RS-485 or RJ12 connectors may be used to connect a single AURORA
inverter or multiple AURORA inverters daisy chained together. Up to 32 inverters can be
daisy chained. Recommended maximum daisy chain length is 1000 metres.
With multiple daisy-chained inverters, each unit must be assigned an address. See paragraph
5.5.6.1 for instructions no how to edit addresses.
The line-termination contact of the last inverter in the chain must be activated (switch S2 -
120
Ω TERM in ON position). See fig.24.
Each AURORA unit is shipped with default address two (2) and S1 switch set to OFF.
In order to ensure optimal communication on the RS485 line, Power-One recommends
connecting Power-One adapter PVI-RS232485 between the first unit in the daisy-chain
system and the computer. See fig.25 for further details.
Equivalent devices available on the market may also be used for this purpose. Power-One
makes no warranties as to proper link operation when such devices are used, as no specific
testing has been conducted to establish their functionality for this particular application.
