System Connection Overlook
NOTE 1:
Make sure that the wires are connected tightly with the terminals.
NOTE 2:
Please install the output breaker between the output terminal and the load, and the breaker
should be qualified with leakage current protective function if necessary.
6)
Put the terminal block cover back to the rear panel of the UPS.
Warning:
● For standard battery pack, there are one DC breaker to disconnect the battery pack and the UPS. But for
other external battery pack, make sure a DC breaker or other protection device between UPS and
external battery pack is installed. 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 highly attention to the rated battery voltage marked on the rear panel. If you want to change the
numbers of the battery pack, please make sure you modify the setting simultaneously. The connection
with wrong battery voltage may cause permanent damage of the UPS. Make sure the voltage of the
battery pack is correct.
● Pay highly attention to the polarity marking on external battery connector and make sure the correct
battery polarity is connected. Wrong connection may cause permanent damage of the UPS.
● Make sure the protective earth ground wiring is correct. The wire current spec, color, position,
connection and conductance reliability should be checked carefully.
● Make sure the utility input & output wiring is correct. The wire current spec, color, position, connection
and conductance reliability should be checked carefully. Make sure the L/N site is correct, not reverse
and short-circuited.
