5-2. Maintenance
The UPS system operates with hazardous voltages. Repairs may only be carried
out 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 check that no current is present and no hazardous voltage exists in the high
capability capacitor terminals such as BUS-capacitors.
Only persons who are sufficiently 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.
Check that no voltage between the battery terminals and the ground is present
before maintenance or repair. The battery circuit of this product 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 maintenance and repair
work.
