5.8 Power Cable Termination
Custom lugs are used with large gauge wires for up to 80 Amps DC (4 AWG) when
connecting to the PEM. These are shipped with the product.The lugs are angled to allow
the cables to be dressed below the cable management tray, thus protecting the circuit
breakers from accidental tripping.
Terminating this lug is identical to terminating standard lugs. To minimize shorting of the
terminals, the lugs must be insulated according to
Figure 5-5
.
5.9 Connecting the Cables to the PEM
In a redundant configuration, each PEM must be connected to a separate DC power
source. The two 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

Heat shrink should be placed as close to the hole as possible (0.15") apart. The heat
shrink tube should be cut approximately at a 30° angle.
