42 Chapter 4 Power supply installationBringing power and ground into the PDUIntroductionInstall BAT/BATRTN wires in pairs. Each pair of wires supplies voltages to amodule through a power harness. The module harnesses are installed inthe cabinet PDU and connected to the modules at the factory. See "Aboutthe power distribution unit" (page 40).To bring DC power and ground into the PDUStep Action1 If you are using a conduit, terminate the 32 mm (1-1/4 in.) or 19 mm(3/4 in.) conduit at the top rear of the cabinet or at the bottom front ofthe cabinet using the knockouts provided. The number of wire pairsyou can run in each conduit depends on the wire gauge.Note: To preserve ground integrity, the conduit must beinsulated.2 Select a power feed with a circuit breaker dedicated to each module,and identify it with an appropriate tag.3 Select a wire size to suit the required feed length from the powersource (see "DC wire gauge tables" (page 36)).4 Use pliers to strip 6 mm (1/4 in.) to 13 mm (1/2 in.) of the insulationfrom one end of all power and ground feed wires.5 Undo the terminal block screws at (-) positions 0, 1, 2, and 3.6 Insert the red wires into terminal block positions 0, 1, 2, and 3.7 Secure the wires in the terminal block by tightening the screws.8 Undo the terminal block screws at (+) positions 0, 1, 2, and 3.9 Insert the black wires into terminal block positions 0, 1, 2, and 3.10 Secure the wires in the terminal block by tightening the screws.11 Select a #10 AWG green wire safety ground and attach it to thecabinet.12 Measure the module ground continuity by touching one multimeterlead to any BATRTN terminal block connector and the other endto the GND terminal block connector. Ensure the measurement isbetween 0-0.5 ohms.—End—Nortel CallPilot1002rp Server Hardware InstallationNN44200-300 01.01 Standard5.0 23 February 2007Copyright © 2007, Nortel Networks Nortel Networks Confidential.
