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: To protect power supplies from input voltage that might be caused
by mis-wired PDMs, before reinstalling the metal cover to the wiring
compartment, apply AC voltage to the PDM (with disengaged PSM) to 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: 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.
NOTE: Three-phase wye AC wire assembly kits can be purchased from Juniper Networks.
Table 100: Supported Three-Phase Wye AC Wire Gauge
DescriptionWire Gauge
5 conductor wires, each wire is 10-AWG5 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: Power connections must be performed by a licensed electrician
only.
15. Verify that the power cord wire connections are correct.
