3 FAQ

If the UPS fails to work properly after starting, please don't jump to the

conclusion of UPS failure. Please refer to the following and try to solve the

problem.

Problem 1

Power supply is normal; UPS is able to output AC 220V after start, yet in the

status of battery inversion with buzzer giving intermittent buzzing.

Possible cause: Unstable AC power input as a result of poor contact of the

junction points, sockets or other connection parts of the electric network feeder

circuit connected to the UPS.

Problem 2

After UPS is installed, and after the electric brake or UPS "ON" button is

switched on, the fuse will be burnt out or tripping occurs.

Cause: wrong connection of three UPS input wires, for example, zero line or

fire wire is connected to UPS earth wire (case ; or wrong connection of three

UPS output wires.

Problem 3

After UPS is started, it outputs AC 220V, yet it's working under bypass status

("BYPASS" keeping lighted).

Possible cause: too-heavy load sustained by the device which exceeds rated

power of the UPS. In such cases, relieve the load to the UPS, or use a UPS of

higher rated power capacity. If it is a temporary bypass status caused by

start-up impact of the load, and returns to proper status automatically, that's

normal operation.

Problem 4

Display and output of the UPS are normal after start. However, the output stops

as soon as load is connected to it.
