Please comply with all warnings and operating instructions in this manual
strictly. Save this manual properly and carefully read the following
instructions before installing the unit. Do not operate this unit before
reading through all safety information and operating instructions carefully:
Transportation
• Please transport the UPS system only in the original package to
protect against shock and impact.
Preparation
• Condensation may occur if the UPS system is moved directly from
cold to warm environment. The UPS system must be absolutely dry
before being installed. Please allow at least two hours for the UPS
system to acclimate to the environment.
• Do not install the UPS system near water or in moist environments.
4
• Do not install the UPS system where it would be exposed to direct
sunlight or near heat sources.
• Do not block ventilation holes in the UPS housing.
Installation
• Do not connect appliances or devices which would overload the UPS
system (e.g. laser printers) to the UPS output sockets.
• Place cables in such a way that no one can step on or trip over them.
• Do not connect domestic appliances such as hair dryers to UPS
output sockets.
• The UPS can be operated by any individuals with no previous
experience.
• Connect the UPS system only to an earthed shockproof outlet which
must be easily accessible and close to the UPS system.
• Please use only VDE-tested, CE-marked mains cable (e.g. the mains
cable of your computer) to connect the UPS system to the building
wiring outlet (shockproof outlet).
• 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 POWER
button to disconnect the mains.
• Prevent fluids or other foreign objects from entering the inside of the
UPS system.
