Field Wiring the MPS-400 Power Supply
The following drawing shows the terminal blocks used to wire the MPS-400
power supply. The drawing also identifies relay switches (S4 and S5) and
LEDs for ground fault, AC power on, and Notification Appliance Circuits 1-4.
The following table lists the functions for the terminal blocks.
