Functional Test
NOTE: Supply to the load is not guaranteed during this test, it should not be carried out if a critical load
is connected to the UPS.
It is possible to carry out a functional test of the UPS to ensure that the load is still supplied in the event
of a mains failure.
Simulate a mains failure by interrupting the mains supply to the UPS. If the UPS is operating correctly
and the batteries are fully charged, an acoustic signal at intervals of 4 seconds will be heard and the “ON”
LED indication “MAINS “indicator (6) at the UPS will be extinguished. Once the interval between the
acoustic signals has decreased to 1 second, the UPS will continue to supply energy for a maximum of 3
more minutes, after which it will be automatically switched off.
The load will be supplied from the batteries during the specified emergency supply period. If this is not
the case, please consult chapter “Troubleshooting” on page 25”.
Restore the UPS mains supply. The UPS is ready for operation. Please note, that the batteries have to be
recharged before the complete emergency supply period is again available.
