• If the UPS is brought from a cold environment into the
installation area, condensation can occur. Before the UPS is
used for the first time, it must be absolutely dry. This requires
a waiting time of at least two hours.
• Never connect the mains power input with the UPS output!
• Make sure that no liquids or foreign objects penetrate the
enclosure!
• Do not cover the vents on the device! Make sure that
children, for example, never insert anything into the vents!
• Never connect any household appliances, e.g. a hair dryer,
to the UPS! Also be careful when operating the device with
power loads. Any feedback to the inverter, e.g. due to short-
term generator operation of the load, must be avoided at all
costs.
• The power outlet should be in the direct vicinity of the device
with easy access to make it easier to activate the AC input or
pull out the plug!
• While the device is in operation, do not pull the plug from the
UPS or from the household outlet (grounded power outlet).
This will cancel the ground for the UPS and all of the load
segments connected.
Danger of electric shock!
Even when the mains power supply has been
disconnected, parts inside the UPS are still
connected to the battery and can give you an
electric shock. Before attempting any maintenance
or service work, always disconnect the battery
circuit!
Battery replacement and servicing must be done or
at least supervised by a qualified technician who is
familiar with the batteries and the safety precautions
that have to be taken!
Do not allow unauthorized access to the
batteries!
When replacing the batteries, please note: Use only identical,
maintenance-free, valve regulated lead batteries with the same
specification as the original batteries.
