3.7.2

Variant with connecting plugs

Warning!

The mains cable must be plugged / drawn into the mains inlet socket of 
the generator only with the generator switched off.
The supply voltage to the high voltage generator is connected directly to 
the mains power supply with the mains power plug via a terminal connec-
tor or a grounding-type plug.
