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.

UPS Module Rating Connection Type
100-225kVA
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.
