Electrical connection
ATTENTION
All electrical work must be carried out by a suitably qualified and competent
person in accordance with local and national safety regulations.
The machine must only be operated at the voltage, frequency and fuse rating shown on the
data plate.
Check that the power supply voltage is within a range of +/-10% of its nominal value.
The frequency of the power supply voltage should not differ by more than 1% of its
nominal value.
The electrical safety of the machine can only be guaranteed when correctly earthed.
Equipotential bonding is required.
Ensure that electrical systems are effectively earthed.
The earth conductor should be connected to the earth terminal
identified by the standard symbol.
If the machine is hard wired to the power supply, connection
should be made via a mains switch with all-pole isolation. The main
switch must be designed to operate at the rated current.
For increased safety, it is recommended to protect the machine with a suitable residual
current device (RCD) with a trip current of 30 mA (DIN VDE 0664).
The machine should be disconnected from the power supply when not used for prolonged
periods.
The power supply on site must be sufficient in cross-section and protected in accordance
with current local regulations.
