4. INSTALLATION

4.1 CONNECTION TO THE MAIN SUPPLY
This unit must be connected to a single-phase 230V - 50 Hz/60 Hz + ground.
Main supply must be protected by fuses or circuit breaker according to the value I1eff written on the specifications of the
power source.
It is strongly suggested to use a differential protection for the operator's safety.

4.2 CONNECTION TO EARTH

For the operator's protection, the power source must be correctly grounded (according to the International Protection
Norms).
It is absolutely necessary to set a good earth connection with the green/yellow wire of the power cable. This will avoid
discharges caused by accidental contacts with grounded pieces. If no earth connection has been set, a high risk of electric
shock through the chassis of the unit remains possible.
