IRING NSPECTION
1. Verify all power connections are tightened per the torque specifications in Table 3.
2. Verify all control wire terminations are tight.
3. Verify all power wires and connections have proper spacing between exposed surfaces, phase-to-
phase and phase-to-ground.
4. Verify that all control wires are run in steel conduit, separate from all power wiring.

Use 75°C copper wire. Select wire size based on the ampacities in Table 5 of this manual, a reprint of
Table 310-16 and associated notes of the National Electrical Code (NFPA 70).
Use commercially available solderless lugs for the wire size required for your application. Refer to
Table 3. Connect wire to the lug using tools and procedures specified by the lug manufacturer.

NOTE: Use the values in this table unless the equipment is labeled with a different torque value.
For "SpaceSaver" modules in the 48" frame, rectifier and bypass input wiring is top-entry,
directly to lugs on top of their respective circuit breakers. DC link and critical bus output
connection are top-entry, to frame-mounted lugs.
Standard modules with top-and-bottom entry have access plates and a wireway on the
right side of the modules. All power connections are to busbars in the wireway.
