Operation - Njoy Balder Series User Manual

Operation


Do not disconnect the earth conductor 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.

Due to the UPS is connected to batteries, its
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/ESCbutton 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 capacitors such as
BUS-capacitors.


Only persons who 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.
