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.
NOTE: The color of each AC power wire might vary.
NOTE: Three-phase wye AC wire assembly kits can be purchased from Juniper Networks.
Table 6: Supported Three-Phase Wye AC Wire Gauge
Wire Gauge
5 x 10-AWG or equivalent
NOTE: It is recommended to 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.
11. Verify that the power cable connections are correct.
12. Screw the retaining nut onto the AC power cord to secure it to the metal wiring compartment.
13. Reinstall the metal PDM wiring cover, and using a number 2 Phillips (+) screwdriver, tighten the four
captive screws on the metal AC wiring compartment.
14. Use the provided plastic cable tie to fasten the AC power cord to the PDM.
15. Verify that the AC power cord does not touch or block access to router components, and that it
does not drape where people could trip on it.
16. Repeat the procedure for the other three-phase wye AC PDMs.
17. Connect the three-phase wye AC power cord mating connector to the AC power cord connector
(see
Figure 38 on page
cord mating connector specifications.
