3�4 Mains connection
Connecting high power devices to the mains could have negative repercussions on mains power quality. Zmax
maximum line impedance demands may arise when connecting such devices. It is the responsibility of the installer
or user to ensure that the device is connected to a line of correct impedance. It is advisable to consult your local
electricity supplier.

Connect a plug of adequate capacity for the current consumption I1 indicated on the data plate. Make sure that the
yellow/green conductor of the power cable is connected to the plug’s earth contact.
It is essential to use the device only if connected to a power supply with an earth conductor. Using the device
connected to the mains without an earth conductor or to a socket without a contact for this conductor constitutes
very serious negligence.
The manufacturer declines all responsibility for damage to people or property that may occur.

The capacity of the overload cut-out switch or fuses, positioned between the power supply network and the device,
must
be adequate for current I1 consumed by the machine. Check the device’s technical data.
CAUTION: If mains power extensions are used, the cable supply cross-section must be at least 2.5 mm².
Do not use extensions longer than 30 m.
The power source can be supplied by a motor generator.
Follow the values indicated in table 1 when choosing the motor generator power.
