5.2. Maintenance
The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified
maintenance personnel.
Even after the unit is disconnected from the mains, components inside the UPS system are still
connected to the battery packs which are potentially 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.
Verify that no voltage between the battery terminals and the ground is present before maintenance or
repair. In this product, the battery circuit is not isolated from the input voltage. Hazardous voltages may occur
between the battery terminals and the ground.
Batteries may cause electric shock and have a high short-circuit current. Please remove all
wristwatches, rings and other metal personal objects before maintenance or repair, and only use tools with
insulated grips and handles for maintaining or repairing.
When replace the 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. The
batteries must be rightly deposed according to local regulation.
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 disassemble the UPS system.
