9.1 Electrical installation
The electrical installation may only be carried out by qualified personnel.
Machines with frequency-controlled motors can be incompatible with certain types of earth leakage circuit
breaker. It is important to know that the machines are designed to provide a high level of personal safety,
which is why items of external equipment such as earth leakage circuit breakers are not necessary. If you
still want to connect your machine across an earth leakage circuit breaker, please remember the following:
• contact a skilled, authorised installation company to ensure that the appropriate type of breaker is chosen
and that the dimensioning is correct
• for maximum reliability, connect only one machine per earth leakage circuit breaker
• it is important that the earth wire is properly connected.
In instances where the machine is not equipped with an omni-polar switch, one must be installed
beforehand.
In accordance with the wiring rules: mount a multi-pole switch prior to the machine to facilitate
installation and service operations.
The connecting cable should hang in a gentle curve.
