Njoy Balder Series User Manual page 4

•
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 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
06
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.
•
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. (only for
