2. Installation and Setup
Connecting a UPS to the Battery Pack
The external battery pack will increase the battery runtime. As a result, recharge time will also increase. Follow the installation diagram below
to connect the battery pack to the UPS. For information on connecting to the UPS terminal block, refer to sections 3.6.2 and 3.7 of the
SUT UPS Owner's Manual.

Notes:
• The DC breaker is tripped (set to off, or the "O" position) at the factory. Do not flip the breaker's actuator lever to the on ("I") position until the battery pack
has been properly connected to the UPS.
• Always use compression lugs with cabling to connect the UPS to the battery pack's terminal block.
• Installer should determine correct wire type based on application.
