Battery wire connect schematic
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 at the rear panel of the UPS.
Warning: (Only for standard model)
● Make sure the UPS is not turn on before the installation. The UPS should not be turned on during wiring
connection.
● Do not attempt to modify the standard model into the long-run model. Particularly, do not try to connect
the standard internal battery to the external battery. The battery type and voltage may be different, if
you connect them together, it maybe cause the hazard of electric shock or fire!
Warning: (Only for long-run model)
● Make sure a DC breaker or other protective device between UPS and the 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 terminal block. 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 wire is correct. The wire current spec, color, position, connection and
conductance reliability should be checked carefully. Make sure the L/N side is correct, not reverse or
short-circuited.
2-4. UPS Installation for Parallel System
If the UPS is only available for single operation, you may skip this section to the next.
1)
Install and wires the UPS according to the section 2-3.
2)
Connect the output wires of each UPS to an output breaker.
3)
Connect all output breakers to a major output breaker. Then this major output breaker will directly
connect to the loads.
4)
Common battery packs or independent battery packs are allowed.
