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).

Directions for replacement

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