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 break-
er. 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 but is recommended. 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 shall hang in a gentle curve.
When connecting to a terminal block, the connection cable shell must be stripped 10-11 mm. The cable area must be
at least 0.5 mm
