♦ Condensation may occur if the UPS is brought from a
cold environment into the room where it is to be
installed. The UPS must be absolutely dry prior to start-
up. As a result, leave it to acclimatise for at least two
hours.
♦ Never connect the mains input and the UPS output!
♦ Ensure that no fluids or foreign bodies can penetrate
the UPS!
♦ Do not block the air vents of the unit! Make sure, for
example, that children do not insert any objects in the
ventilation openings!
♦ Do not connect household appliances such as
hairdryers to the UPS!
♦ The mains connection should be near the unit and
easily accessible to facilitate disconnecting the AC
input or pulling out the plug!
♦ During operation, do not disconnect the mains
connection cable from the UPS or from the socket
outlet in the building (shockproof socket), otherwise the
protective grounding of the UPS and all the loads
connected to it will be cancelled.
Danger! Electric shocks!
Even after the mains voltage has been
disconnected, the components within the UPS
remain connected to the battery and can thus
cause electric shocks. It is therefore imperative
to disconnect the battery circuit before carrying
out any maintenance or repair work!
If it is necessary to replace the battery or carry
out maintenance work, this must be done by or
under the supervision of a specialist familiar with
batteries and the necessary safety precautions!
Only authorised persons are allowed in the
vicinity of the batteries!
