Power connection

An AC connector is used for connecting the PS 407 10A and the PS 407 10A R to both an

AC and a DC supply.

Polarity reversal of L+ and L-

The polarity reversal of L+ and L- with supply voltages of between 88 and 300 VDC has no

effect on the function of the power supply. The connection should be made as described in

the instructions in the Installation Manual.
