1. Verify there is no power going to the chassis.
2. Verify the chassis is properly grounded. For information on frame-grounding the chassis,
refer to “Frame-Grounding a BTI7802 Chassis” on page 90.
3. Using a wire stripper tool, strip the other end of the DC PEM connector and cable and
prepare it, as needed, for connection to the DC power distribution unit in your plant.
4. Install the DC PEM.
Loosen the latch thumbscrew and pull the latch to the open position.
5. Position the module edges onto the slot guides, and gently slide the module along
the guides until the DC PEM connects to the backplane.
6. Push in the latch to lock the module in place. Carefully tighten the thumbscrew.
NOTE: You will not be able to plug in the DC cable connector if the latch
is not locked in place.
