Route the input and output cables through either the top or bottom of the cabinet
to the UPS terminals. See Figure 4‐4 for wiring access information and Figure 4‐6
and Figure 4‐7 for common rectifier feed terminal locations or Figure 4‐8 through
Figure 4‐10 for separate rectifier feed terminal locations.
Top Access Wiring.
Remove the top conduit plate from the top of the UPS.
Identify all conduit requirements and mark their location. Drill and punch all
conduit holes in the top conduit plate prior to mounting on the UPS. Install the
conduit plate and install all conduit runs into the plate. Pull the wiring through the
conduit into the wiring area.
Bottom Access Wiring.
Remove the bottom conduit plate from the inside bottom
of the UPS. Identify all conduit requirements and mark their location. Drill and
punch all conduit holes in the bottom conduit plate prior to mounting on the UPS.
Install the conduit plate and install all conduit runs into the plate. Pull the wiring
through conduit into the wiring area.
4.
Locate the external wiring terminal hardware kit packed on the bottom left side
of the ISBM section.

If installing a UPS with separate rectifier feeds, proceed to Step 6; otherwise,
proceed to Step 8.
NOTE
On a UPS that is configured for separate rectifier inputs, all sources that feed the separate rectifier
inputs must be derived from a common ground point.
6.
Connect phase A, B, and C rectifier input power wiring from the utility source to
each UPM rectifier input terminal block in the UPS cabinet. See paragraph 3.2.2
on page 3-7, Table 3‐6 on page 3-11, and Table 3‐11 on page 3-13 for wiring and
termination requirements.
