4.8.2 External Power Wiring Installation
To install wiring to connections:
1. Remove one top screw and two bottom screws securing the UPS left front panel (see Figure 4-2). Lift the
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 4-19 through Figure 4-21 for wiring access information and terminal locations.
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 ISBM section.
Identify all conduit requirements and mark their location. Drill and punch all conduit holes in the bottom
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.
4. Locate the external wiring terminal hardware kit packed on the bottom left side of the ISBM section.
5. 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.
