6 Operations
6.1 Check Before Power-On
● AC power cable colors comply with local regulations.
● The input and output are not short-circuited.
● Cables and terminals are securely connected.
● Battery cables and terminals are correctly connected, and voltages comply
with industry standards.
● The UPS is properly connected to battery strings.
● Input circuit breakers and load circuit breakers are OFF.
● Power cables and signal cables are correctly identied.
● The phase sequence of the input power is correct.
● Cables are neatly routed and securely bound according to requirements.
● The equipment is installed and cables are routed in ways that facilitate
modication, capacity expansion, and maintenance.
● Parallel cables in a parallel system are properly connected.
● Devices are properly grounded.
● The voltage dierence between the neutral wire and the ground cable is less
than 5 V AC.
● The mains input voltage ranges from 120 V AC to 280 V AC (after the UPS is
powered on, the mains input voltage ranges from 80 V AC to 280 V AC). The
battery voltage range is as follows: (Number of batteries x 10.8 V DC) to 280
V DC.
