InfraStruXure 20kW System: Installation, Operation, and Maintenance 63

Maintenance

Parts Replacement

You can replace power modules, battery units, communication cards, and intelligence modules on the

InfraStruXure 20kW System without affecting power to the load equipment.

Follow these guidelines whenever you replace parts in the system:

• Replace a failed module only when the load conditions and settings of the system support

redundancy.

• Replace battery units only when the system is not in the on-battery operating mode.

• Remove batteries and power modules before you move or ship the system to avoid damage in

transit. Remove these modules even if you are moving the system a very short distance.

• You will need two people to remove and install power modules and battery units.

• Replace a faulty battery unit if it fails less than six months from the time of installation. Replace

the entire battery module (four battery units) if a battery unit fails after operating for six months

or more.

• The InfraStruXure 20kW System display interface will list an alarm condition when a module

fails.

How to obtain replacement parts

To obtain a replacement part, contact APC Customer Support at a number on the back cover of this

manual 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. If possible, call APC Customer Support from a telephone that is within reach of the

InfraStruXure 20kW System display interface so that you can gather and report additional

information to the representative.

3. 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.

4. If the InfraStruXure 20kW System is within the warranty period, repairs will be performed free

of charge. If it is not within the warranty period, there will be a charge for repair. Review APC’s

warranty policy on page 81.

5. If the InfraStruXure 20kW System is covered by an APC service contract, have the contract

available to provide information to the representative.
