Chapter 4 Removal and Replacement Procedures
Removing and Installing PEMs
To install a DC-input PEM, follow these steps:
Step 1
Ensure that the system (earth) ground connection has been made. For ground connection installation
instructions, see the
“Establishing the System Ground” section on page 3-52
.
Step 2
Verify that power is off to the DC circuit for the PEM that you are installing. As an added precaution,
place the appropriate safety flag and lockout devices at the source power circuit breaker, or place a piece
of adhesive tape over the circuit breaker handle to prevent accidental power restoration while you are
working on the circuit.
Step 3
Install the PEM partially into the chassis so that you still have access to the PEM terminal block screws.
(See
Figure 4-62
.)

Step 5
After ensuring that all wire connections are secure, install the PEM in the bay.
