Electrical connection

Dangerous electrical voltage! Connection of the machine as well as electrical
inspections, maintenance and repair may only be carried out by qualified personnel
or under the supervision and supervision of a qualified electrician!
1. Check that the neutral connection and protective earthing are functioning properly
2. Check that the supply voltage and current frequency correspond to the specifications of
the machine
A deviation from the value of the supply voltage of ± 5% is permissible.
A short-circuit fuse must be provided in the power supply system of the machine!
3. Find the required cross-section of the supply cable (it is recommended to use a cable type
H07RN (WDE0282), taking measures to protect against mechanical damage) in a current
capacity data sheet.
4. Make sure that the power source is protected by a residual current circuit breaker.
5. Connect the unit only to a properly grounded outlet.
6. When using an extension cable, make sure that it is dimensioned appropriately for the
connected load of the machine (the connected load can be found in the technical data).
You can find the correlation between cable cross-section and cable length in specialist
literature or consult an electrician.
