Figure 41: AC Power Supply Module
The AC power system provides dual redundant feeds (INP0 and INP1). Each PSM takes in two AC feeds
and uses one of the two. One input feed is active during operation. Each feed is a single-phase AC system
200–240 VAC derived from a three-phase delta or wye AC input system. These feeds are set by the input
mode DIP switch located on the AC PSM. Move the input mode DIP switch to the on or off position to
determine the power supply feeds (see
