Operation; Maintenance, Service And Faults - Delta INX Series User Manual

Please use only VDE-tested, CE-marked mains cable (e.g. the mains cable of
z
your computer) to connect the UPS system to the building wiring outlet (shock-
proof outlet).
Please use only VDE-tested, CE-marked power cables to connect the loads to
z
the UPS system.
When installing the equipment, it should ensure that the sum of the leakage cur-
z
rent of the UPS and the connected devices does not exceed 3.5mA.

1.4 Operation

Do not disconnect the mains cable on the UPS system or the building wiring
z
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
z
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
z
to disconnect the mains.
Prevent no fluids or other foreign objects from inside of the UPS system.

1.5 Maintenance, Service and Faults

The UPS system operates with hazardous voltages. Repairs may be carried out
z
only by qualified maintenance personnel.
WARNING:
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 bat-
z
teries 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 pre-
z
cautionary measures may replace batteries and supervise operations. Unauthor-
ized persons must be kept well away from the batteries.
WARNING:
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!
