♦ Do not block the air vents of the unit! Keep children away
from the unit and ensure that objects are never inserted
through the air vents!
♦ Do not connect household appliances such as hairdryers to
the UPS! Also take care when working with motor loads. It is
essential to avoid back-feeding the inverter, e.g. if the load is
intermittently operated in regenerative mode.
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 o

under the supervision of a specialist familiar with
batteries and the necessary safety precautions!
Only authorised persons are allowed in the

When replacing the batteries, the following must be observed:
Only ever use identical maintenance-free sealed lead
batteries with the same data as the original batteries.
Danger! Explosive!
Never throw batteries into open fire.
Never open or damage batteries. (Electrolyte
may leak out and damage skin and eyes. It may
be toxic!)
Batteries can cause electric shocks and high
short-circuit currents.
Take the following safety precautions when working with the
batteries:
♦ Take off watches, rings and other metallic objects!
♦ Always use tools with insulated handles!
