Battery Module Storage and Replacement

(Symmetra

PX and Smart-UPS

VT)

Directions for replacement

Battery Enclosures with four batteries in a row.

APC recommends that a whole battery module (one row of batteries) is replaced at the same time to

ensure optimal run-time (see Example 1). However it is only necessary to replace two batteries at the

same time according to Example 2 and 3 in the table below.

Battery Enclosures with two modules in a row.

Replace both batteries in one row at the same time.

Warning: Only trained persons familiar with the construction and operation of the

equipment, as well as the electrical and mechanical hazards involved, may install

and remove system components.

Caution: Wait until the system is ready to be powered up before installing Battery

Modules in the UPS. Failure to do so can result in a deep discharge of the batteries and

cause permanent damage (the time from the battery installation time till the UPS is

powered up should not exceed 72 hours or 3 days).

Caution: Do not mix battery units. Replace with same model.
