• 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 individual with no previous experience.
• Connect the UPS system only to an earthed shock-proof outlet which must be easily accessible and close to the UPS system.
• Please use only VDE-tested, CE-marked, ISI-marked mains cable (e.g. the mains cable of your computer) to connect the UPS system to the building wiring outlet (shock-proof outlet). Please use only VDE-tested, CE-marked, ISI-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 3.5 mA.
• UPS is designed for linear load applications.

Operation

• Do not disconnect the mains cable in the UPS system or the building wiring outlet (shock-proof 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 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 into the UPS system.

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 still connected to the battery may be 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. Only persons adequately familiar with batteries and with the required precautionary measures may replace batteries and supervise operations. Unauthorized persons must be kept well away from the batteries.
• Caution – Risk of electric shock. If the battery circuit is not isolated from the input voltage, hazardous voltages may occur between the battery terminals and the ground. Before touching, please verify that no voltage is present. Batteries may cause electric shock and have a high short-circuit current. Please take the precautionary measures specified below and any other measures necessary when working with batteries:
• remove wristwatches, rings and other metal objects
• use only tools with insulated grips and handles.
• When changing batteries, install the same number and same type of batteries.
• Do not attempt to dispose off batteries by burning them. This could cause battery explosion.
• Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It may be toxic. Please replace the fuse only with the same type and amperage in order to avoid fire hazards.
• Do not dismantle the UPS system.
• Connect UPS to short circuit protected building wiring.
• The UPS system has internal fuses on both DC & AC inputs. Those devices do not protect the upstream cables connected to DC & AC inputs and upstream breakers or fuses shall be set up in accordance with AC & DC wires ratings to meet the local national electrical code standard.
