MD-1000I / MD-2000I / MD-3000I Maintenance and Service
Remember that after the test the batteries are low. The UPS system will need
to run several hours (min. 5 hr) on the mains before it reaches about 80% ca-
pacity.
If you fail to perform a battery back-up test regularly, we suggest, for the sake
of prevention, replacing the batteries every two years in order to safeguard the
availability of your system against failure caused by battery degradation.
