HIGH IMPEDANCE GROUND SOURCES - If the supply source is a high impedance ground (IT) type, the input
neutral conductor must be connected from the source of supply. If there is no output neutral connected to the
UPS, the neutral–forming transformer kit may be used instead of pulling a neutral from the source. If the load
requires a neutral, then an input neutral conductor must be pulled into the UPS. In no circumstances shall a
neutral to ground bonding jumper be installed in the UPS.
Use the procedures in the following paragraphs to connect the external and battery power wiring.

To install wiring to connections:
1. Remove one top screw and two bottom screws securing the UPS left front panel (see
panel straight up to remove it from the panel hanger bracket at the top of the cabinet.
2. Remove the screws securing the internal safety shield panel and remove the panel to gain access to the
input, output, and battery terminals. Retain the hardware for later use.
3. Route the input and output cables through either the top or bottom of the cabinet to the UPS terminals.
See Figure 31
Top Access Wiring. Remove the top conduit plate from the top of the ISBM section. Identify all conduit
requirements and mark their location. Drill and punch all conduit holes in the top conduit plate prior to
mounting on the ISBM section. Install the conduit plate and install all conduit runs into the plate. Pull wiring
through conduit into the ISBM section 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.

The ISBM and UPM sections are shipped with debris shields covering the ventilation
grills on top of the sections (see
installation is complete. However, remove the shields before operating the UPS. Once
the debris shields are removed, do not place objects on the ventilation grills.
Remove the ISBM section top or bottom conduit landing plate to drill or punch conduit
holes (see Figure 31).
If the load requires a neutral, a bypass source neutral must be provided. If the load does
not require a neutral and there is no neutral conductor connected at the bypass input, a
neutral to ground bonding jumper must be installed. DO NOT install both a source
neutral and a bonding jumper. See
Bonding jumper must be copper wire.
