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

Please use only VDE-tested, CE-marked power cables to connect the loads to
z
z
the UPS system.
When installing the equipment, it should ensure that the sum of the leakage cur-
z
z
rent of the UPS and the connected devices does not exceed 3.5mA.
Temperature Rating - Units are considered acceptable for use in a maximum
z
z
ambient of 40°C (104°F).
For PLUGGABLE EQUIPMENT, the socket-outlet shall be installed near the
z
z
equipment and shall be easily accessible.
Caution:
The unit is heavy. Lifting the unit requires a minimum of two people.

1.4 Operation

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

The REPO and USB circuits are an IEC 60950-1 safety extra low voltage (SELV)
z
z
circuit. This circuit must be separated from any hazardous voltage circuits by re-
inforced insulation.

1.5 Maintenance, Service and Faults

The UPS system operates with hazardous voltages. Repairs may be carried out
z
z
only by qualified maintenance personnel.
Caution - risk of electric shock. Even after the unit is disconnected from the
z
z
mains (building wiring outlet), components inside the UPS system are still con-
nected to the battery and electrically live and dangerous.
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.
