7. INSTALLATION
7.1. Connection to the power supply
The equipment must be supplied with 230V - 50 Hz/60 Hz single-phase + earth.
The power supply must be fitted with a device (fuse or circuit breaker) corresponding to the I1eff value
indicated on the nameplate of the equipment.
The installation of a differential protection device is not compulsory except for the safety of the users.
7.2. Connection
For the protection of the users, the equipment must be correctly connected to the earthing installation
(INTERNATIONAL SAFETY RULES).
It is essential to establish a good earth connection via the green/yellow conductor of the power cable in
order to avoid discharges due to accidental contact with live parts in contact with earth. If the earth
connection is not made, there is a risk of electric shock to the machine casing.
Avoid placing the device in rooms with high dust concentration, humidity or excessive ambient
temperatures.
