Terminating this lug is identical to terminating standard lugs. To minimize shorting of the
terminals, the lugs must be insulated according to
Figure 5-4 .
5.9 Connecting the Cables to the PEM
In a redundant configuration, each PEM must be connected to a separate DC power source. The
2 separate inputs on a single PEM should be connected to the DC same source. Power is
introduced to each PEM’s terminal block on the front of the module (power input cable and
return cable). The lugs provide secure contact for the cable and prevent the power cables from
rotating. A plastic housing covers the power feeds and returns and is attached with one screw.
Refer to
Figure DC Power Connection Detail on page 95 for detail
Procedure - Connect Cables to PEM
Insulation should be placed as close to the hole as possible (0.15") apart. The insulation
tube should be cut approximately at a 30° angle.
NOTICE
To cable a dual breaker DC system, read all cautions and warnings, properly ground the
equipment by following the procedure in
Grounding the Shelf
, and follow these steps.
This procedure assumes that the PEMs are preinstalled in the shelf.
Cables may or may not be preinstalled at the branch circuit or power distribution unit.
If the DC power cables are not connected to the branch circuit or power distribution unit,
connect the power cables to the PEMs before connecting the DC power cables to the
external power source.
If the DC power cables are connected to the branch circuit or power distribution unit, a
qualified service person must confirm that the power to the cables is terminated (off)
before continuing the steps to attach the cables to the PEMs.
In either case, use a multimeter to check the PEM end of the terminals to confirm there is
no power present.
