NOTE 1: Make sure that the wires are connected securely with the terminals.
NOTE 2: Please install the output breaker between the output terminal and the load, and the breaker
should have leakage current protective function if necessary.

Put the terminal block cover back at the rear panel of the UPS.
Warning:
● Make sure a DC breaker or other protective device between UPS and the external battery pack is
installed for added safety. If not, please install it carefully. Switch off the battery breaker before
installation.
NOTE: Set the battery pack breaker in “OFF” position and then install the battery pack.
● Pay special attention to the rated battery voltage marked on the rear panel. If you want to change the
numbers of the battery in a chain, make sure you modify the UPS setting accordingly. Connection with
wrong battery voltage may cause irreversible damage of the UPS.
● Pay special attention to the polarity marking on external battery terminal block. Connection with wrong
battery voltage may cause irreversible damage of the UPS.
● Make sure the protective grounding/earthing wiring is adequate. The current spec, color, position,
connection and conductance reliability of the wire should be verified.
● Make sure the utility input & output wiring is rated correctly. The current spec, color, position, connection
and conductance reliability of the wire should be verified. Make sure the L/N side is correct, not reverse
