CONNECTION

ATTENTION!
Connection to the grid must comply with the current regulations.
Make sure the mains voltage and frequency match the values given on the motor rating plate.
Danger due to electricity!
 Before starting work on the unit or system, take the following precautions:
- make sure the machine is NOT powered;
- take steps to prevent the power from being reconnected;
 The terminal box must not contain:
- foreign bodies;
- impurities;
- moisture.

The machines are supplied without control panel.

Wire sizes must be able to take maximum current absorbed by the electric motor.

The electric motor must be protected against the effects of short circuit, overload, phase failure and reconnection that can cause
overvoltages.

Before connecting to the grid, make sure to connect the earth wire to the respective electric motor terminal indicated by the
following symbol .

Use the openings in the cable clamps to run the power cables inside the terminal box.

After making the terminal box connections, tighten the cable clamp to secure the cables.


INVERTER POWERED ELECTRIC MOTOR

ATTENTION!
The performance of the unit may vary in case of power supply with inverter, and frequency or voltage different from the rated values. For
the performance of an inverter-powered unit with frequency or voltage different from the rated values, contact the FPZ After-Sales
Service.

Connect the electric motor thermal protectors, to protect the inverter-powered electric motor.

The power supply via inverter is always the responsibility of the installer, who must ensure compliance with the standards and the
installation procedures indicated by the inverter manufacturer.

ROTATION DIRECTION

The machines must be used respecting the rotation direction indicated by the
arrow on the electric motor fan cover.

To check the rotation direction, switch the motor on briefly and observe the
fan.

To change the rotation direction, invert the power cable connections,
leaving the earth connection unchanged.
