Route the input and output cables through either the top or bottom of the cabinet
to the UPS terminals. See Figure 4-16 through Figure 4-19 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.
Locate the external wiring terminal hardware kit packed on the bottom left side
of the ISBM section.
Using hardware from the external wiring terminal hardware kit (see Table 3-11 on
page 3−15), connect phase A, B, and C rectifier input power wiring from the utility
source to the rectifier input terminals in the ISBM section. See paragraph 3.2.2
on page 3−8 for wiring and termination requirements.
Using hardware from the external wiring terminal hardware kit (see Table 3-11 on
page 3−15), connect phase A, B, and C, and Neutral (if required) bypass input
power wiring from the utility source to the bypass input terminals and neutral
terminals in the ISBM section. See paragraph 3.2.2 on page 3−8 for wiring and
termination requirements.
If wiring a distributed bypass system, proceed to Step 7; otherwise, proceed to
Step 9.
Using hardware from the external wiring terminal hardware kit (see Table 3-11 on
page 3−15), connect phase A, B, and C, and Neutral power wiring from the output
and neutral terminals of each UPS unit to the customer−supplied tie cabinet or
load distribution panel. See paragraph 3.2.2 on page 3−8 for wiring and
termination requirements.
Proceed to paragraph 4.8.2.
Using hardware from the external wiring terminal hardware kit (see Table 3-11 on
page 3−15), connect phase A, B, and C, and Neutral (if required) power wiring
from output terminals and neutral terminals to the critical load. See
paragraph 3.2.2 on page 3−8 for wiring and termination requirements.
