Verifying the Installation
If the input or output system is changed, the short
circuit copper bar status 
and cable connections at input and output ports are correct.
The input power phase sequence is correct. No short circuit occurs on the 
input and output terminals (a 
multimeter is used for the check).
Cables and terminals are securely connected.
Battery cables and terminals are connected correctly, 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 identified.
Ground cables are reliably connected. The voltage between the neutral 
wire and the ground cable is less than 5 V AC.
Mains startup input voltage range: 120
280 V AC(after being powered on, 
can range from 80 V AC to 280 V AC); battery voltage: greater than the 
number of batteries multiplied by 10.8 V DC
Failed
1. After the check is complete, install the UPS 
front panel.
2. It is recommended that the UPS be sheltered 
after installation (before power-on) with baffle 
plates or plastic bags to prevent dust on the 
top of the UPS or inside the UPS.
