Warning:
Make sure the UPS is not turned on before installation. The UPS should not be turned on
during wiring connection.
There is one DC breaker to disconnect the battery pack from the UPS. Make sure this DC
breaker is in the off position.
Note:
Set the battery pack breaker to “OFF” position and then install the battery pack.
Attention should be paid to the rated battery voltage marked on the rear panel. If you want
to change the numbers of battery packs, please make sure you modify the setting
simultaneously. The connection with wrong battery voltage may cause permanent damage
to the UPS. Make sure the voltage of the battery pack is correct.
Attention should be paid to the polarity marking on external battery terminal block, making
sure that the correct battery polarity is connected. Wrong connection may cause permanent
damage to the UPS.
Make sure the protective earth ground wire is correctly installed. The wire current
specification, color, position, connection, and conductance reliability should be checked
carefully.
Make sure the utility input and output wiring is correct. The wire current specification, color,
position, connection, and conductance reliability should be checked carefully. Make sure the
