1-5. Maintenance, service and faults

The UPS system operates with hazardous voltages. Repairs may be carried out only by

qualified maintenance personnel.
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.
EN
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 ground.
Before touching, please verify that no voltage is present!
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
－use only tools with insulated grips and handles.
When changing batteries, install the same number and same type of batteries.

Do not attempt to dispose of batteries by burning them. This could cause battery

explosion.
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 with the same type and amperage in order to avoid fire

hazards.
Do not dismantle the UPS system.
