Adjusting mains voltage for toroidal mains transformer
Before putting the Bosch Emissions Analysis into operation, you
must check that the set voltage of the toroidal mains transformer
is the same as that of the mains voltage. The Bosch Emissions
Analysis is factory-set to 230V.
! The transformer mains voltage may only be set by authorized
Service personnel. The Bosch Emissions Analysis must be
off circuit.
1.
Remove housing cover.
2.
Remove connection cable 5 of the toroidal mains transformer
(see diagram) from the mains input connector.
3.
Connect the required connection cable (see diagram) to the
mains input connector.
Possible settings (see table):
230V (factory setting), 245V, 125V, 110V, 95V.
4.
Close housing cover.
5.
Perform safety test as per regulations in country of use (e.g.
to VDE in Germany).
