Note: Where the cable leaves the cable rack, the cable must be protected with fiber paper throughout
the system.
1. Apply the cable tags, provided with the system, to both ends of the supply and return cables.
2. Ensure that power is off at the central office power distribution board for the circuits being wired.
Use a multimeter.
3. Remove the clear plastic cover from the back of the 3U PDP.
4. Run, form, and dress the cable from the power distribution board to the 3U PDP.
5. For the A side and B side, strip the cable ends, slide a one-inch length of clear heat-shrink tubing
over and past the portion of stripped cable.
Figure 36: Lug Installation
6. Apply non oxidizing grease to the stripped end of the cable, and install the lug. The stripped cable
must fill lug completely to the end of the barrel of the lug and be visible in the end window of the
lug.
7. Double crimp the lugs onto the cable end using the embossing crimper.
8. Slide the one-inch length of clear tubing from Step 7 over the crimped lug. Apply heat and
heat-shrink the one-inch length of clear tubing around the crimped lug.
9. Fasten the lugs of the cables to the respective A-side and B-side power and return on the 3U PDP.
Torque to 36 inch-pounds.
10. Verify correct connection with a multimeter by running continuity check.
PDP Alarm Card
Monitoring of the power input is provided by the alarm card. Three DIP switches on the card allows
this monitoring to be turned on or turned off. If the monitoring is not turned off for unconnected
inputs, the alarm card detects a loss of input power to these inputs and the corresponding LED for
the breakers will be red and an alarm is indicated.
The DIP switches monitor Bus A (S2) and Bus B (S3) individual power inputs. Monitoring of specific
alarm cable inputs is provided by switch S4.
Procedure — Replacing the PDP Alarm Card
Warning: All power sources must be removed from the PDP before reomoving the
alarm card assembly. All alarm contacts will signal an alarm state when all power sources
are removed or when the alarm card is removed.
1. Observe the safety and ESD precautions in
Safety and Pre-Installation Requirements
.
2. Remove all power source from the PDP. The removal of the power source will cause an alarm.
