After verifying the input power connector has been wired correctly, disconnect power from the
connector by turning off its upstream circuit breaker.
Shelf Power Activation
After the wiring to the input power connector has been tested and verified, it can be plugged into and
secured to the Power Shelf.
To secure the input power connector and activate the Power Shelf:
1.
Using a DMM, verify that power is disconnected from the input power connector.
2.
Insert the wired connector into the input connector of the Power Shelf and secure the connector
in place by torqueing the screws to 4 N-m (3.0 ft-lbs) with a T-20 star driver.
3.
Activate electrical power to the Power Shelf via its circuit breakers. The Power Shelf is activated
and ready for testing.
C13 Voltage Tests
Verify that the Power Shelf has the correct voltage on the C13 receptacles as shown in the table below.
C13 Receptacles
(as viewed from rear of Power Shelf)
Phase A Input Power
Left three C13 receptacles (same voltage as Phase A)
Phase B Input Power
None
Phase C Input Power
Right three C13 receptacles (same voltage as Phase C)
To verify correct voltage on the C13 receptacles:
•
With a DMM, verify that the C13 receptacles have power. As shown below, Phase A (L1) power
should be available on the left side C13 receptacles and Phase C (L3) power should be available on
the right side C13 receptacles.
