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.
3.
Route the input and output cables through either the top or bottom of the cabinet
to the UPS terminals. See Figure 4‐23 for wiring access information and
Figure 4‐24 through Figure 4‐26 for common rectifier feed with MSS terminal
locations, Figure 4‐24, Figure 4‐27, and Figure 4‐28 for common rectifier feed
with CSS terminal locations, or Figure 4‐24 and Figure 4‐29 through Figure 4‐31
for separate rectifier feed 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.
