•
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.
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.
•
Only persons are 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. 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 in this
manual 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 of 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.
