Power Connections (Ac) - Northern Telecom Meridian Meridian 1 Installation Manual

Power connections (ac)

One IG-L6-30 or L6-30 receptacle must be within 2.4 m (8 ft) of the
pedestal. Instead of using the power plug provided, you can hard-wire the
PDU to the power source. In this case, you should use #10 AWG
conductors routed through 3/4-inch conduit. Connect the leads to the L1,
L2, and GND terminations on the field wiring terminal block on the PDU.
Use a separate safety ground. The safety ground must be #6 AWG or larger
and must connect the pedestal to the service panel ground bus. Depending
on the distances between columns and the service panel, you may run
safety ground wiring independently from the AEM column to the service
panel, or you may daisy-chain the safety ground wiring between the AEM
column and the Meridian 1.
DANGER
Risk of equipment damage
Failure to follow grounding procedures can result in
an unsafe or faulty system.
Procedure 1xxx
Power connections (ac)
1 Make sure the power cord is disconnected from the power source.
2 Measure the resistance between the ground pin on the power plug and
a ground lug on the rear of the pedestal.
See Figure 5. The resistance should be zero ohms. If the resistance is
greater than .5 ohms, check the power cord connections.
