Top Access Wiring. Remove the top conduit plate from the top of the UPS. Identify all conduit
requirements and mark their location. Drill and punch all conduit holes in the top conduit plate prior to
mounting on the UPS. Install the conduit plate and install all conduit runs into the plate. Pull the wiring
through the conduit into the 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.
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.
6. Connect phase A, B, and C rectifier input power wiring from the utility source to each UPM rectifier input
terminal block in the UPS cabinet. See paragraph 3.2.3, Table 3-8, and Table 3-13 for wiring and
termination requirements.
7. Proceed to Step 11.
8. Using hardware from the external wiring terminal hardware kit (see Table 3-11), connect phase A, B, and C
rectifier input power wiring from the utility source to the rectifier input terminals in the UPS cabinet. See
paragraph 3.2.3 for wiring and termination requirements.
9. If installing a UPS configured as an Input Output Module (IOM), proceed to Step 14; otherwise, proceed
to Step 10.
10. Using hardware from the external wiring terminal hardware kit (see Table 3-11), 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 UPS cabinet. See paragraph 3.2.3 for wiring and termination requirements.
11. If wiring a distributed bypass system, proceed to Step 12; otherwise, proceed to Step 14.
12. Using hardware from the external wiring terminal hardware kit (see Table 3-11), 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 3.2.3 for wiring and termination
requirements.
13. Proceed to paragraph 4.6.3.
14. Using hardware from the external wiring terminal hardware kit (see Table 3-11), connect phase A, B, and
C, and Neutral (if required) power wiring from output terminals and neutral terminals to the critical load.
See paragraph 3.2.3 for wiring and termination requirements.
15. Proceed to paragraph 4.6.3.
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.
