4.5 Compressed air circuit hook-up
Connection to the line can be made by means of a rubber or Rilsan (Din 74324) hose with a
suitable fitting. We recommend to use a supply hose with an internal diameter of not less than
10 mm.
The working pressure of the user’s net must be, with full load not less than 7/8 bar/atm.
Hook up the line to the slide valve mounted on the FRL air treatment unit and check by moving
the black collar, that the pressure on the gauge reads 7/8 bar/atm.
If necessary, turn the knob on the FRL air treatment unit (DWG. A1.16) to bring the pressure to
the indicated level.
The filter’s function is to filter the dust and moisture out of the air, which may otherwise damage
the valves and pneumatic actuators. When condensate and impurities reach the maximum level
in the container, empty the container by means of the relevant breather.
The approximate air consumption, calculated on the maximum work load is 20.7 lt/work cycle.
During the first few jobs, check that the pressure reading on the gauge does not fall below 6
bar/atm.
4.6 Connection of the electric equipment
Do not hook up the machine to the electricity mains until it has been properly positioned and
fully assembled.
The machine is supplied with the net power supply characteristics requested by the customer.
Before connecting to the mains, check the voltage on the machine ratings plate.
CAUTION:
CHECK THE MACHINE POWER SUPPLY VOLTAGE CAREFULLY.
TO AVOID CAUSING DAMAGE TO THE ELECTRONIC-ELECTROTECHNICAL
COMPONENTS, THE VOLTAGE MUST COMPLY WITH THE FOLLOWING CONDITION:
Va = Vt +/- 5% Vt.
Whereby: Va = actual power supply voltage
Vt = machine rating plate voltage
The user's electricity network must comply with IEC 64-8 standards (CENELEC HD 384, IEC
364-4/41).
The network must have:
- a unipotential ground circuit;
