Ordinary Problems
If the UPS is operated with normal method, the panel will display the
current working status. The following are ordinary UPS failure problematics :
Problem 1: The UPS will not switch to electric supply status after turning
on.
Solution : Check whether the power cord is well connected with the
electricity network socket; whether the input AC fuse has burned out. (There
is one spare fuse in the input fuse socket, please use fuse of same
specifications).
Problem 2: Unplug the input power cord after it is turned on, but the
UPS cannot switch to Inverter supply status.
Solution : The battery voltage is too low, output is overloaded, or output
short circuit; please charge the battery or change it, check whether the
output is overloaded and reduce the load, or whether the output loop is
short-circuited.
Maintenance
If the UPS is not being used for a long time ,then it should be charged 8
～
10
hours every three month. If possible, please discharge the battery with the
computer or 100W light bulb for 1
～
3 minutes. The purpose of discharging is
to activate the battery. The battery is only allowed for long-time storage after
it is fully charged; or the battery capacity will reduce due to performance
erosion after long-time stall. The long-time under voltage (or even zero
voltage) due to battery self-discharging will “kill” the battery.
Regularly check the power supply and input and output lines of all
equipments, so as to guarantee the reliability of peripheral lines.
