Open-Rack Batteries
When batteries other than Liebert battery cabinets are used, a remote battery disconnect switch with
overcurrent protection is required per the National Electrical Code. Refer to Required Battery Discon-
nect Rating in the site planning data tables in
Appendix A
for recommended overcurrent protection
ratings. Contact your Liebert sales representative for more information.
1. Install battery racks/cabinets and batteries per manufacturer’s installation and maintenance
instructions.
2. Verify battery area has adequate ventilation and battery operating temperature complies with
manufacturer’s specification. Installations using vented lead-acid batteries MUST have adequate
ventilation to remove explosive gases per local and national codes.
3. Low voltage control wiring must be kept separate from power wiring and run in separate
conduits.
4. Ensure that battery racks are properly grounded according to code requirements in your area.
If you have any questions concerning batteries, battery racks or accessories, contact your local sales
representative or Liebert Global Services at 1-800-LIEBERT.
!
CAUTION
Cables between batteries and the UPS should be run in matched
pairs, positive-with-negative, within each conduit or cable run.
Grouping like-polarity cables together (i.e., positive-with-positive
and negative-with-negative) can cause stress or damage to the
cables, conduit or buswork.
