II. Connect UPS input cable
1. Prior to connection, make sure that the wall socket or distribution
switchboard to be connected has been reliably grounded;
2. Make sure that the input mains voltage is within tolerances;
3. Make sure that the socket capacity is correct: 1kVA UPS adopts
socket with capacity greater than 10A, 2kVA/3kVA UPS adopts
socket with capacity greater than 16A. As to 3kVA UPS, if needing
larger input current (for instance, when the mains voltage is usually
low and the UPS assumes full load), please connect the UPS to
distribution switchboard. When the load is fixed and far lower than
