DANGER
This UPS may have internal batteries. The batteries are designed to deliver a
large amount of energy and an incorrect connection may lead to a short

equipment. In order to avoid damages to the equipment or injuries to
personnel, only commissioning personnel are allowed to perform the
connection of these batteries.

The default battery settings of the UPS are for 12 V VRLA batteries. If you need
to use any other type of batteries, contact your Eaton representative. For the
