c. Insert the wire labeled L2 into the input terminal labeled B2.
d. Insert the wire labeled L3 into the input terminal labeled C2.
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.
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 the PSM power switch turned
off). Verify that the 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 to remove power
from the PDM and install the metal cover.
NOTE: Three-phase delta AC wire assembly kits can be purchased from Juniper Networks.
Table 92: Supported Three-Phase Delta AC Wire Gauge
Description Wire Gauge
4 conductor wires, each wire is 6-AWG 4 x 6-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.
