Insert the power module connected directly to the supply module or the
PM-A
socket of the adapter into the fuse base with the aid of a slip-on handle with cuff.
Result:
The power module now draws its supply voltage from the bus bar and
also passes it on to the supply module, whose software starts directly
afterwards.
CAUTION
Even when switched off, the power switch (thyristor switch) does
not represent a galvanic isolation. For this reason, it must always
be assumed that the outgoing cable is energised!
With a voltage tester (for example, Duspol), the mains voltage can
be measured on the cable at any time. Only under load (for
example due to the load resistance integrated in the voltage
tester), does the voltage drop to a much lower value.
