WARNING:
Do not touch the power connectors on the PDM. They can contain
dangerous voltages.
Connect Power to a Three-Phase Wye AC Power Distribution Module
CAUTION:
Do not mix AC and DC power modules within the same router.
To connect an AC power cord to an AC power source for the three-phase wye AC PDM:
1.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to an approved site ESD grounding point. See the instructions for your site.
2.
Switch off the dedicated customer-site circuit breakers. Ensure that the voltage across
the AC power source cable leads is 0 V and that there is no chance that the cable
leads might become active during installation.
3.
Detach the ESD grounding strap from the approved site ESD grounding point, and
connect the strap to one of the ESD points on the chassis.
4.
Switch off (
O
) the AC PSMs and disengage all AC PSMs.
5.
Using a number 2 Phillips (+) screwdriver, unscrew the four captive screws located
on the either side of the metal AC wiring compartment (four screws total per PDM).
6.
Remove the cover of the metal AC wiring compartment.
7.
Unscrew the retaining nut from the AC power cord.
8.
Insert the wires of the AC power cord through the hole of the retaining nut and rubber
grommet.
9.
Insert the wires of the AC power cord through the hole of the metal wiring
compartment.
10.
Connect the wires to the AC terminal block on the three-phase wye AC PDM (see
). Loosen the input terminal or grounding point screw, insert each
wire into the grounding point or input terminal, and tighten the screw (see
for approved AC wire gauge).
NOTE:
The terminal connections have either slotted screws or hex screws.
Use a 1/4-in. slotted screwdriver for the slotted screws. Use a 5/32-in.
(4-mm) Allen wrench for the 5/16-in. hex screws.
