2.4 Operation
1. Do not disconnect the mains cable on the UPS system or the building wiring
socket outlet during operations since this would cancel the protective earthing
of the UPS system and of all connected loads.
2. The UPS has its own internal power source (batteries). The output terminals
may be live even when the UPS is not connected to the AC supply.
3. Ensure that no fluids or other foreign objects can enter the UPS system.
2.5 Maintenance and Service
1. Caution - risk of electric shock.
Even after the unit is disconnected from the mains power supply (building
wiring socket outlet), components inside the UPS system are still connected to
the battery and are still electrically live and dangerous. Before carrying out any
kind of servicing and/or maintenance, disconnect the batteries and verify that
no current is present.
2. Only persons adequately familiar with batteries and with the required
precautionary measures may exchange batteries and supervise operations.
Unauthorized persons must be kept well away from the batteries.
3. 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
