5.1 Checking Before Powering On the UPS



AC power cable colors comply with local electrical regulations.



No short circuits occur in inputs and outputs.



Cables are securely connected.



Battery cables are correctly connected to battery terminals. The battery voltage meets the
requirements.



Cables are properly connected between the UPS and batteries.



Input circuit breakers and load circuit breakers are OFF.



Power cables and signal cables are correctly identified.



The input phase sequence is correct.



Cables are neatly routed and securely bound.



Devices are installed and cables are routed in ways that facilitate modification, capacity
expansion, and maintenance.



Parallel cables are properly connected.



The UPS is properly grounded.



The voltage between the neutral wire and the ground cable is less than 5 V AC.



The mains supply voltage is 80–144 V AC during power-on (80–144 V AC after
power-on). The battery voltage is greater than 46.5V DC.
