5. ELECTRICAL CONNECTIONS
Personal safety
– unit integrity
To prevent injuries to persons or damage to things, the unit electrical connection
must be done by qualified electricians in compliance with safety procedures.
Before doing the electrical wiring, make sure the line is not powered and cannot be
turned on by external personnel.
The unit is equipped with an equipotential protection circuit in compliance with standard EN
60204-1 1998. In order to have an effective protection system against indirect contacts, the power
line must be outfitted with a circuit breaker that will automatically interrupt power in the event of
an insulation failure, in compliance with the regulations 413.1 of standard IEC 364-4-41.
Unless otherwise indicated on the identification plate, the electrical wiring must be done with a 3P +PE
cable with adequate section and characteristics in compliance with the applicable standards. The unit is
shipped from the factory with a 5 metre long 1.5 mm2 4G cable. If necessary, a 5G cable can be supplied
in replacement.
We recommend stopping the purifier when the machine tool is not running in order to:
- avoid useless electricity consumption
- avoid uselessly generating noise
- increase filter working life.
5.1. Power cord replacement:

Loosen the cable clamp on the back of the unit (a).

Loosen the 4 front screws on the control panel and remove the front cover.

Insert the power cable until you reach the control panel.

Fit a pin fork terminal on the three phase terminals and a spade terminal on the protection terminal.
Insert three phase wires on the connecting terminals of the motor protector switch L1
– L2 – L3 and
tighten them with max. torque of 2 Nm.

Make sure the motor protector switch calibration matches the electrical power data indicated on the
plate.

Insert the protection cable in the yellow/green terminal and tighten the screw.

Reassemble the front cover and loosen the screws.

Tighten the rear cable gland and check that the cable is sealed securely.

Connect the power supply cable to the mains supply using proper components that comply with the
applicable standards.

When installation is completed, release the two latches and lift the top part of the unit to check the
impeller.

In compliance with safety regulations, in sequence push the start and stop buttons and make sure
the rotation of the impeller (rotation is clockwise on the extraction side) matches that of the arrow on
the impeller case.

If the arrow and the direction of the impeller rotation do not match, after having sectioned the
power line, invert the two-phase power supply connection.

Restart the unit and check that the rotation direction matches the arrow.
