Pay attention to the adherence to VDE-guidelines! In case measurements are to 
be done at the live parts of the circuit, the circuit must then be connected to a 
safety-isolating transformer. 
 
In no case should measurements be conducted on the circuit, when it is directly 
connected to the mains (risk to life!). Although the circuit is simply a replica, in 
case of non-functioning it should be checked only by an expert, because he is 
adequately familiar with the applicable safety regulations. 
2.2
 For the first start-up (functional test) please use a separate mains supply, 
whose voltage is fed via the rectifier D1 (“+”, at the plus-marking of D1 and “-” at 
the minus marking of D1).
