Caution - risk of electric shock. Even after the unit is disconnected from the mains
(building wiring outlet), components inside the UPS system are still connected to the
battery and electrically live and dangerous.
Before carrying out any kind of service and/or maintenance, disconnect the batteries
and verify that no current is present and no hazardous voltage exists in the terminals
of high capability capacitor such as BUS-capacitors.
Only persons are adequately familiar with batteries and with the required
precautionary measures may replace batteries and supervise operations.
Unauthorized persons must be kept well away from the batteries.
Caution - risk of electric shock. The battery circuit is not isolated from the input
voltage. Hazardous voltages may occur between the battery terminals and the
