Important Safety Warning
Please comply with all warnings and operating instructions in this manual strictly. Save this manual properly and
read carefully 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 the environment.
o Do not install the UPS system near water or in moist environments.
• Do not install the UPS system where it would be exposed to direct sunlight or near heater.
• Do not block ventilation holes in the UPS housing.
Installation
• Do not connect appliances or devices which would overload the UPS system to the UPS output sockets.
o Place cables in such a way that no one can step on or trip over them.
o 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 con-
nected loads.
• The UPS system features its own, internal current source (batteries). The UPS output sockets or output ter-
minals block may be electrically live even if the UPS system is not connected to the building wiring outlet.
o In order to fully disconnect the UPS system, first press the OFF/Enter button to disconnect the
mains.
o Prevent no fluids or other foreign objects from inside of the UPS system.
Maintenance, Service, and Faults
• The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified mainte-
nance 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.
