Input Wiring (TB1)
To connect the input wiring, follow these steps:
1. Locate the
input wiring
access,
remove the
knockout
and pull the
three input
wires
through it,
allowing
some slack
for
installation.
2. Secure the conduit to the rear panel of the
UPS.
3. Input Power cables connect to screw
terminals on the Input Terminal Block located
to the right of the Bypass Voltage Terminal.
Connect the wires to the block connections
as shown below. Using a torque wrench, turn
the screws clockwise until tightened to the
proper torque value 2.5 - 3.0 Nm
(22-26 in-lb). Insert the ground wire through
the grounding lug and tighten it to the proper
torque value.
Grounding Conductor Installation
An insulated grounding conductor must be
identical or larger in size, insulation material, and
thickness as the grounded and ungrounded
branch circuit supply conductors. This cable
must be green with or without one or more yellow
stripes and is to be installed as part of the branch
circuit that supplies the unit or system.
The grounding conductor is to be grounded to
earth at the service equipment or, if supplied by a
separately derived system, at the supply
transformer or motor generator set.
Output Wiring (TB3)
Output wiring may be configured one of two
different ways (240/120 or 208/120). Refer to the
chart and diagram below when configuring the
output wiring.

Note
The S5K Modular UPS contains an isolation
transformer that generates a neutral
conductor for the connected equipment. The
UPS is a separately derived source and
contains a neutral to ground bonding jumper.
A grounding electrode conductor (GEC) must
be installed in accordance with national and
local wiring codes and regulations.
