Installing safety ground/protective earth and
logic return wiring
Follow Procedure 4 to install safety ground/protective earth and
logic return wiring.
Procedure 4
Installing safety ground/protective earth and logic return wiring
1 Make sure the power cord is disconnected from the power source.
Note: As a safety precaution, disable the circuit of each column at the
service panel.
2 Remove the air intake grill.
3 Using a volt/ohm meter, measure the resistance between the ground pin
on the power plug and a ground lug on the rear of the pedestal (see
Figure 28).
Note: The resistance should be 0 ohms; if it is greater than 0.5 ohms,
check the power cord connections.
CAUTION
System Failure
Failure to follow grounding procedures can result in
unsafe or faulty equipment. See Communication
Server 1000M and Meridian 1: Large System
Planning and Engineering (NN43021-220) for a
complete description of approved ground sources
and methods.
