4.8 Installing UPS External and Battery Power Wiring
NOTE The ISBM and UPM sections are shipped with debris shields covering the ventilation grills on top of
the sections (see Figure 4-17). Do not remove the debris shields until 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.
NOTE Remove the ISBM section top or bottom conduit landing plate to drill or punch conduit holes (see
Figure 4-18 on page 4−20).
NOTE 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 Table 3-4 on page 3−9 for
neutral bonding jumper wire sizes. Bonding jumper must be copper wire.
Use the procedures in the following paragraphs to connect the external and battery
power wiring.
4.8.1 External Power Wiring Installation
To install wiring to connections:
1. Remove one top screw and two bottom screws securing each ISBM section left
and right front panel (see Figure 4-2 on page 4−3). Lift the panels straight up to
remove them from the panel hanger brackets at the top of the cabinet.
2. Remove the screws securing the top and bottom internal safety shield panels
and remove the panels to gain access to the input, output, and battery terminals.
Retain the hardware for later use.
