WARNING:
by mis-wired PDMs, before reinstalling the metal cover to the wiring
compartment apply AC voltage to the PDM (with disengaged PSM) make sure
that two LEDs on the PDM are lit green and that the AC voltage between AC
terminal blocks A1-B1, B1-C1, C1-A1, A2-B2, B2-C2, and C2-A2 for three-phase
delta 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 delta AC wire assembly kits can be purchased from Juniper Networks.
