• Please use only VDE-tested, CE-marked power cables to connect the
loads to the UPS system.
• When installing the equipment, it should ensure that the sum of
the leakage current of the UPS and the connected devices does not
exceed 3.5mA.
Operation
• Do not disconnect the mains cable on the UPS system or the building
wiring outlet (shockproof socket outlet) during operations since this
would cancel the protective earthing of the UPS system and of all
connected loads.
• The UPS system features its own, internal current source (batteries).
The UPS output sockets or output terminals block may be electrically
live even if the UPS system is not connected to the building wiring
outlet.
• In order to fully disconnect the UPS system, first press the OFF/Enter
button to disconnect the mains.
• Prevent fluids or other foreign objects from entering the inside of the
UPS system.
• WARNING: This is a category C2 UPS product. In a residential
environment, this product may cause radio interference, in which
case the user may be required to take additional measures.
Maintenance, service and faults
• The UPS system operates with hazardous voltages. Repairs may be
carried out only by qualified maintenance personnel.
• Caution - risk of electric shock. Even after the unit is disconnected
from the mains (building wiring outlet), components inside the UPS
system are still connected to the battery and electrically live and
dangerous.
• Before carrying out any kind of service and/or maintenance,
disconnect the batteries and verify that no current is present and no
hazardous voltage exists in the terminals of high capability capacitor
such as BUS-capacitors.
