UPS Rating
5KVA/6KVA
8KVA/10KVA
The AC input block connects the two phase utility
supply, voltage and frequency is 88/152-155/269
Vac and 50/(60) Hz.
The AC output block connects the two phase
critical loads, voltage and frequency is 100/200
110/220 115/230 120/208 120/240 127/220VAC
and 50/(60) Hz.
The battery connector connects the external
battery module, voltage is +/- 120VDC.

4 .4 .2 AC source connection

Connect AC input to the AC power source. The
sequence of two phase can be connected freely.
The wrong sequence will not alarm for 2-phase
UPS system when the UPS is powered. A common
N (neutral) wire must be securely connected for
proper UPS operation. A warning message will
indicate if the N wire is missing or not connected
properly. The UPS will show warning message as "
Warning 1C". Then, the UPS will transfer to battery
mode if battery pack is connected or transfer to
standby mode and no output if no battery pack is
connected.

4 .4 .3 DC source connection

Connect the UPS to the ±120V battery module
using a dedicated cable. Ensure that the ports on
the back of the UPS and the battery pack are
properly connected. Press the battery start
button and the machine will enter Standby Mode.
If the machine is not powered on within 1 minute,
it will automatically shut down.
• MAKE SURE THE MAINS SUPPLY AND THE TOTAL LOAD DEMAND ARE WITHIN UPS SPECIFICATIONS.
• BEFORE WIRING, MAKE SURE THE AC INPUT AND BATTERY POWER ARE COMPLETELY CUT OFF.
• MAKE SURE THE BREAKERS, INCLUDING AC INPUT BREAKER, AC OUTPUT BREAKER AND DC BREAKER,
ARE ALL IN THE OFF POSITION.
