Connect Power to a Three-Phase Delta AC Power Distribution Module
To connect an AC power cord to an AC power source:
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 (

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.
Put the wires of the AC power cord through the hole of the retaining nut and rubber
grommet.
10.
Put 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
