150kW InfraStruXure PDU—Operation and Configuration
Connect an EPO switch to the user connection plate and test the switch
1. Connect the switch to the EPO connection point terminals located on the bottom side of the
PDU user connection plate. Read the label next to the terminal block to determine which
terminals to connect to for the signal type you are using:
– Contact Closure—Normally Open
– Contact Closure—Normally Closed
– 24VAC/VDC—Normally Open
2. Verify that the EPO DIP switches on the PDU monitoring unit are configured properly for the
signal type you are using. The labels above the switches and the figure below show the correct
settings for both the Normally Open (NO) and Normally Closed (NC) position.
Note
The default setting on the EPO interface on the PDU monitoring unit is for a Normally
Open (NO) switch.
