4. Make sure that the operational mains supply is loaded evenly (mains
symmetry). You will find the connection variants (A, B, C) in the above
table.
5. The terminal for the protective conductor "PE" must be connected.
Potential equalization missing!
Serious faults or disturbances can be caused in the
machine and the electronic circuit if the terminal (PE)
is not connected.
-> Always connect terminal .
6. Close the plug (2) and connect it to the main switch.
