power supply (switch off the mains input externally or disconnect the UPS from
the mains, e.g. by unplugging it).
Make sure that no fluids or foreign bodies enter the UPS.
3.6 Handling batteries
Warning
– danger of electric shocks and burns.
Batteries can cause electric shocks and are capable of producing high short-
circuit currents which can also inflict burns.
Unauthorised persons must be kept away from batteries.
Do not place batteries against heat sources and do not throw them into a fire as
they might explode!
Do not open or destroy batteries. The electrolyte thereby released is extremely
dangerous to persons and to the environment (danger of chemical burns to skin
and eyes, toxic).
Defective batteries must be disposed of in an environmentally-friendly manner.
Never throw batteries into the regular refuse.
The local waste disposal regulations must be observed.
3.7 Maintenance, servicing and faults
Warning
– danger of electric shocks.
The UPS remains connected to the battery circuit even after it has been
disconnected from the mains power supply and has a dangerous voltage
potential. Therefore always disconnect the battery circuit before carrying out
servicing or maintenance work and make sure that the equipment is isolated
from the supply.
Work on batteries may only be performed and monitored by personnel with
appropriate technical knowledge about the required precautions.
Unauthorised persons must be kept away from batteries.
When working on the UPS, the following precautions must be taken:
o
Remove wristwatches, rings and other metallic objects
o
Only use electrically-insulated tools
The UPS must not be dismantled.
