Terminal block wiring diagram for HV 100KL /120KL/ 180KL/ 200KL &
LV 50KL/60KL/90KL/100KL
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:
● Make sure a DC breaker or other protecti
ve 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 t
he 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.
2-5. 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.
