Figure 36: Connecting Power to a Three-Phase Wye AC Power Distribution
Module
CAUTION:
Wire label configuration is for Juniper Networks supplied cable
only. If using your own cable, make sure you use the proper connections.
To connect wires to the terminal block that serves three PSMs:
a. Insert the grounding wire into the grounding point labeled
b. Insert the wire labeled
c. Insert the wire labeled
d. Insert the wire labeled
e. Insert the wire labeled
WARNING:
In order to protect power supplies from input voltage that may
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 264VAC when
measured with a DVM. Then turn off the AC breaker de-energizing the
PDM and install the metal cover and engage all AC PSMs.
