Maintenance, servicing and faults
 The UPS system operates with hazardous voltages. Re-
pairs may only be carried out by qualified maintenance
personnel.
 The battery is the only component of this unit that should
be replaced by the user.
 Caution – risk of electric shock. Even after the unit is dis-
connected from the mains power supply (outlet socket),
components inside the UPS system are still connected to
the battery and are still electrically live and dangerous. Be-
fore carrying out any kind of servicing and / or mainte-
nance, disconnect the batteries and verify that no current is
present.
 Only persons adequately familiar with batteries and with
the required precautionary measures may replace batteries
and supervise operations. Unauthorised 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 earth.
 Batteries may cause electric shock and have a high short-
circuit current. Please take the precautionary measures
specified below and any other measures necessary when
working with batteries:
- Remove wristwatches, rings and other metal objects.
- Only use tools with insulated grips and handles.
 When replacing batteries, install the same number and
same type of batteries.
 Do not attempt to dispose of batteries by burning them.
This could cause the batteries to explode.
 Do not open or destroy batteries. Escaping electrolyte can
cause injury to the skin and eyes. It may be toxic.
 Please replace the fuse only by a fuse of the same type
and of the same amperage in order to avoid fire hazards.
 Do not dismantle the UPS system.
