4.6.2 Battery wiring
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 ‐ 4 for wiring access information and Figure 4 ‐ 6 and Figure 4 ‐ 7 for common
rectifier feed terminal locations or Figure 4
‐
8 through Figure 4
‐
10 for separate rectifier feed terminal
locations.
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.
CAUTION
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.
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 3.2.2, Table 3 ‐ 6, and Table 3 ‐ 11 for wiring and
termination requirements.
7. Proceed to Step 10.
8. Using hardware from the external wiring terminal hardware kit (see Table 3 ‐ 9), 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 3.2.2 for wiring and termination requirements.
9.
Using hardware from the external wiring terminal hardware kit (see Table 3 ‐ 9), 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 3.2.2 for wiring and termination
requirements.
10.
If wiring a distributed bypass system, proceed to Step 11; otherwise, proceed to Step 13.
