10. If the battery system includes a battery monitoring option, the battery monitoring
components should be attached and wired into the circuit at this time. The battery
monitor system will have separate installation instructions.
11. Install the Polycarbonate Retainer and Raceway on each cabinet battery shelf. Dress the
inter-shelf battery terminal connection cables into these raceways to contain these
cables.
12. Proceed to Item #4 in Section 7.2.5 of this manual.

ONNECTIONS
Review the attached system drawings and schematics for model specific
information on DC output connections.
Wire should be sized for a maximum voltage drop of 0.5 volt.
Battery cabinets that are not supplied with an incorporated DC output disconnect
device must have an appropriate disconnect device provided external to the cabinet.
Verify that the output breaker is in the off/open position before making any DC
connections to additional cabinets or to the UPS. Also verify that the UPS charger
is not running.
1. Open the front doors on the cabinet and check for any noticeable problems or damage that
may have occurred during shipment.
2. Review the attached system schematic located inside the cabinet doors to find the location
of the jumper that has been left off in the middle of the battery string for added safety
during installation and shipping. This jumper will be installed later.
3. Check and re-torque all internal battery connections, as shipping may have caused these
connections to come loose. Proper torque values are noted on the system drawing and can
also be found on most battery cases.
4. Connect main cables from the UPS or charger source to the battery cabinet output. The
battery cabinet output connection point will vary depending on the cabinet configuration.
The main output connection point may be directly to the circuit breaker, to the fuse block,
or to a terminal block or bus bars. Review the supplied cabinet drawing for information on
the battery cabinet output. All cables should be sized per NEC and any other local codes
pertaining to this equipment. Refer to the UPS or charger manual for wiring external
batteries. Note: Make sure charging source is disconnected before making these
connections.
5. Connect the jumper that was left off during shipment and install as shown on the system
schematic. Torque connections properly.
