4.8.2 Individual (per rectifier position) Input
Mains inputs terminal blocks are located across the rear of the distribution shelf behind a
removeable access panel. Figure 4-7 below represents the view from above when looking
from the rear of the system.

Figure 4-7 Individual AC Input Terminals
Each input requires a L/L1, N/L2 and Mains Ground connection to be made. Mains cable
size is max. 5mm² or 10AWG.
CAUTION
Individual rectifiers operate from a wide AC input supply in the range 85V
to 300V. Full output power is available above 180V and is automatically adjusted back
linearly from 180VAC down to 85V.
The input to each rectifier is fully isolated in the system and individual connections can be
made both Line to Neutral and Line to Line provided that the above limits are not exceeded.
CAUTION
The input to each rectifier is fully isolated in the system and individual
connections can be made both Line to Neutral and Line to Line provided that the above
limits are not exceeded.
All rectifiers must be connected to the same voltage, i.e. 230VAC L-N or 240VAC L1-L2.
