d. Insert the wire labeled L3 into the input terminal labeled C2.
e. Insert the wire labeled N into the input terminal labeled N2.
WARNING:
by mis-wired PDMs, before reinstalling the metal cover to the wiring compartment,
apply AC voltage to the PDM (with disengaged PSM) and make sure that two LEDs
on the PDM are lit green and that the AC voltage between AC terminal blocks
A1-N1, B1-N1, C1-N1, A2-N2, B2-N2, and C2-N2 for three-phase wye PDM is
not more than 264 VAC when measured with a digital voltage meter (DVM). Then
turn off the AC breaker, de-energizing the PDM, and install the metal cover and
engage all AC PSMs.
NOTE:
Three-phase wye AC wire assembly kits can be purchased from Juniper Networks.
Table 106: Supported Three-Phase Wye AC Wire Gauge
Wire Gauge
5 x 10-AWG or equivalent
NOTE:
We recommend that you use the proper gauge wire in order for the cable clamps to
hold the AC cables. Using smaller gauge wiring will result in the cable clamps not tightening
properly.
WARNING:
12. Verify that the power cable connections are correct.
13. Screw the retaining nut onto the AC power cord to secure it to the metal wiring compartment.
14. Reinstall the metal PDM wiring cover, and using a number 2 Phillips (+) screwdriver, tighten the four
captive screws on the metal AC wiring compartment. Apply between 10 lb-in. (1.13 Nm) to 12 lb-in.
(1.35 Nm) of torque to each screw. Do not overtighten the screws.
To protect power supplies from input voltage that might be caused
Power connections must be performed by a licensed electrician only.
