Warning:
(Only for standard model)
●
Make sure the UPS is not turned on before installation. The UPS should not be turned on during wiring
connection.
●
Do not try to modify the standard model to 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 causes the hazard of electric shock or fire!
Warning:
(Only for long-run model)
●
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.
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 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 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.
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 UPSs 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) Each UPS is connected to an independent battery pack.
5) Remove the cover of parallel share current cable port on the UPS, connect each UPS one by one with the
parallel cable and share current cable, and then screw the cover back again.
NOTE:
The parallel system can not use one battery pack. Otherwise, it will cause system permanent failure.
