ELECTRICAL AND PNEUMATIC CONNECTIONS
WARNING
All operations required for the electrical connections of the equipment must be carried out
exclusively by a qualifi ed electrician.
Before connecting the air supply system, make sure the machine is set up as in fi g. 4:
pedal totally downwards.
- The electrical supply must be suitably sized in relation to:
• the machine input power as specifi ed in the corresponding machine data plate;
• the distance between the machine and the power supply hook-up point, so that voltage drops
under full load do not exceed 4% (10% during start-up) compared with the rated voltage specifi ed
on the data plate.
- The operator must:
• fi t a power plug on the power supply lead in compliance with the relevant safety standards (A fi g 5);
• Connect the machine to an effi cient grounding circuit in compliance with the relevant electric stan-
dards, provided with a circuit breaker (residual current set to 30mA);
• fi t fuses to protect the power supply line, rated as indicated on the general wiring diagram in this
manual.
- In order to prevent the machine from being used by unauthorized personnel, it is advisable to
disconnect the power supply plug when the machine remains idle (switched off) for long periods.
WARNING
A good grounding connection is essential for correct operation of the machine.
NEVER connect the earth wire to a gas or water pipe, telephone line or any other unsuitable
objects.
Check that the pressure and fl ow-rate provided by the compressed air system are compatible with
those required for proper operation of the machine - see “Technical Data” section. For correct machine
operation the compressed air supply line must provide a pressure range from no less than 8 bar to
no more than 16 bar.
Connect the compressed air system by means of a supply pipe connected to the intake of the air
treatment unit on the REAR SIDE of the machine base.
Check that there is air lubrication oil in the Lubricating unit; refi ll if there is little or no oil. Use SAE20 oil.
The customer must provide an air cut-off valve upstream of the air treatment and regulating device
supplied with the machine.
WARNING
Connection 1 should be considered as an emergency valve to
disconnect the machine from the air line (fi g.6)
