11.2 HORIZONTAL INSTALLATION ON FOOT
The units can be installed with the working axis horizontal
as follows:
Using a special foot for horizontal fixing
Non-compliance with the unit's intended use can
cause serious injury.
Regularly check the fixing of the unit to the support structure.
Excessive vibration of the unit can seriously damage the machine.
ATTENTION !
Check the motor rotation direction. (see par. 5.2 ROTATION DIRECTION)
11.3 ELECTRIC MOTOR
Danger due to electricity!
Improper behaviour can cause serious injury.
Work on the electrical equipment (installation, maintenance) must only be carried out by qualified and authorised electricians!
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;
- open the terminal box only after making sure the power is disconnected!
The terminal box must not contain:
- foreign bodies;
- impurities;
- moisture.
Close the terminal box with the lid and seal the openings of the cable glands to prevent dust, water and moisture from entering.
Check the seals regularly.
If a faulty unit is touched there is risk of electric shock!
Install the motor circuit breaker.
Have an electrician regularly check the electrical equipment.
ATTENTION!
In case of various motor starts in the space of an hour, there are limitations which can seriously damage the unit if ignored.
Regarding this, refer to the electric motor instruction manual.
11.3.1
CONNECTION
ATTENTION!
Incorrect connection of the motor can seriously damage the unit.
The power supply of the motor and any auxiliary equipment must use wires of suitable thickness in order to avoid abnormal overheating
and high voltage drops.
Make sure the supply voltage and frequency match the rating data.
Connect the earth wire of the motor to the terminal marked with the following
symbol
always before connecting to the mains and check the leakage capacity. The
earth wire is identified by its colour (yellow/green).
Connect to the mains by referring to the diagram in the terminal box.
Use the openings in the cable glands to run the power cables inside the terminal box.
Once the terminal board connections are done, tighten the cable gland to secure the
cables.
The electrical connection terminals must be tightened to prevent high contact resistances
and consequent overheating.
Ensure the insulation gaps and distances between the different wires as required by the standards.
All screws used for closing the terminal board must be tightened down. Damaged screws must be immediately replaced with
screws of equivalent or better quality.
