Service
If the UPS requires service do not return it to the dealer. Follow these steps:
1. Review the problems discussed in Troubleshooting to eliminate common problems.
2. If the problem persists, contact APC Customer Service through the APC web site, www.apc.com/support.
Note the model number of the UPS, the serial number, and the date purchased. If you call APC Cus-
tomer Service, a technician will ask you to describe the problem and attempt to solve it over the phone.
If this is not possible, the technician will issue a Returned Material Authorization Number (RMA#).
If the UPS is under warranty, repairs are free.
3. Pack the UPS in its original packaging. If this is not available, refer to www.apc.com/support for informa-
tion about obtaining a new set.
Pack the UPS properly to avoid damage in transit. Never use Styrofoam beads for packaging. Damage
sustained in transit is not covered under warranty.
Always DISCONNECT THE BATTERY before shipping in compliance with U.S. Department of
Transportation (DOT) regulations. The battery module(s) may remain in the UPS; it does not have
to be removed.
4. Mark the RMA# on the outside of the package.
5. Return the UPS by insured, prepaid carrier to the address given to you by Customer Service.
