Cable Entry/Exit
Perform the cable knockouts and provide the fittings
and conduits for this cabinet. Bottom or right-side
cable entry is possible. Refer to Figure 2–1, Figure 2–2,
and Figure 2–3.
Input Conductor
Sizing
Determine the input conductor sizing for the UPS. The
circuit rating needs to be matched to the input circuit
breaker for the unit being installed. Refer to Table 2–1
for the input circuit breaker ratings for the different
UPS models.
MAINS1 Input
Conductors (supplied
by the electrician)
Provide four wires for the MAINS1 input; three phase
conductors and a ground. If only one power source
is to be used for the MAINS1 and MAINS2 inputs,
the MAINS1 and MAINS2 busbars must be jumpered
together using the correct gauge wire.
MAINS2 Input
Conductors (supplied
by the electrician)
Provide five wires for the MAINS2 input; three phase
conductors, a neutral
1
(all four of equal ampacity), and
a ground. If only one power source is to be used for
the MAINS1 and MAINS2 inputs, the MAINS1 and
MAINS2 busbars must be jumpered together using the
correct gauge wire. If no neutral
1
is available from
the building distribution system (for example, DELTA
only service entrance), a UPS Auxiliary Cabinet with
an input isolation transformer may be used to derive a
neutral for the UPS cabinet.

If an HA32A-Cx cabinet is being installed, a neutral conductor is not required.
