5.2 AMBIENT CONDITIONS
The machine must be placed in an working area, the environmental conditions of which
do not exceed the following limit values:
Temperature:
+5…+40°C (41…104°F)
Relative humidity of air:
85% or less
Electromagnetism
Surrounding appliances should not cause such
electromagnetic perturbations, which exceed the
general standards established for workshop machinery
.
Altitude:
max. 2200m / 7200ft
5.3 CONNECTION OF THE MACHINE TO THE SOURCES OF ENERGY
5.3.1 CONNECTION TO THE ELECTRIC NETWORK
a
DANGER! Disconnect the electric current to the supply cable before
starting to carry out the connection - fatally dangerous voltage.
a
DANGER! Even if the main switch is in “0” (OFF) position, the switch
and the supply cable still are alive - fatally dangerous voltage
a
DANGER! Only a qualified and authorized person is allowed to carry
out the connection of the F-400 machine to the mains.
The terminals for connection of the external supply cable of the F-400 machine are
located in the electric box. Pay special attention to the correct earthing of the machine.
Check that the working voltage indicated on the machine and the supply voltage
coincide. Also check that the current value of the overload circuit breakers corresponds
to the current value of the motors. The machine can be supplied for a voltage range of
200-240V/50Hz/60Hz and of 380V-480/50Hz/60Hz. Check the correct connection with
the help of the circuit diagram delivered with the machine. This circuit diagram will be
found in the pocket of the electric box door. Compare the diagram with the nameplate of
the machine.
¨
NOTE! If the residual-current circuit breaker is wanted to use
with machine power supply system, a pulsating DC type (type A) is
recommended to be used. The EMC-filters of the machine may cause
disturbance tripping for regular (type AC) residual-current circuit breakers.
