How to determine if you need a replacement part

To determine if you need a replacement part, contact APC Customer Support and follow the
procedure below so that the APC Customer Support representative can assist you promptly:
1. In the event of a module failure, the display interface may show additional “fault list” screens.
Press any key to scroll through these fault lists, record the information, and provide it to the
representative.
2. Write down the serial number of the unit so that you will have it easily accessible when you
contact APC Customer Support.
3. If possible, call APC Customer Support from a telephone that is within reac h of the UPS di splay
interface so that you can gather and report additional information to the representative.
4. Be prepared to provide a detailed description of the problem. A representative will help you
solve the problem over the telephone, if possible, or will assign a return material authorization
(RMA) number to you. If a module is returned to APC, this RMA number must be clearly
printed on the outside of the package.
5. If the unit is within the warranty period, repairs or replacements will be performed free of
charge. If it is not within the warranty period, there will be a charge.
6. If the unit is covered by an APC service contract, have the contract available to provide
information to the representative.

How to return parts to APC

Call APC Customer Support to obtain an RMA number.
To return a failed module to APC, pack the module in the origi nal s hippin g mater ials, and ret urn i t by
insured, prepaid carrier. The APC Customer Support representative will provide the destination
address. If you no longer have the original shipping materials, ask the representative about obtaining
a new set. Pack the module properly to avoid damage in transit. Never use styrofoam beads or other
loose packaging materials when shipping a module. The module may settle in transit and become
damaged. Enclose a letter in the package with your name, RMA number, address, a copy of the sales
receipt, description of the problem, a phone number, and a check as payment (if necessary).
Note: Damages sustained in transit are not covered under warranty.
