Connect Power to a Three-Phase Delta AC Power Distribution Module
To connect an AC power cord to an AC power source for the three-phase delta AC PDM:
CAUTION: Do not mix AC and DC power modules within the same router.
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 power supply modules (PSMs) and disengage all AC PSMs.
5.
Verify that the correct three-phase delta AC PDMs are installed and secured in the chassis before
connecting power cables.
NOTE: The power cables must be uninstalled and removed from the PDM before removal of
the PDM from the chassis.
6.
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).
7.
Remove the cover of the metal AC wiring compartment.
8.
Unscrew the retaining nut from the AC power cord.
9.
Insert the wires of the AC power cord through the hole of the retaining nut and rubber grommet.
10. Insert the wires of the AC power cord through the hole of the metal wiring compartment.
11. Connect the wires to the AC terminal block on the three-phase delta AC PDM (see
page
61). Loosen the input terminal or grounding point screw, insert each wire into the grounding
point input terminal, and tighten the screw (see
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.
