3 KOMPONENTS HAVE TO BE CHANGED
Change the bridge on the STP4 to 380V or 415V
The transformer STPSP must be soldered to the right connec-
tions
380V: middle connection of transformer - two wires
415V: end connection of transformer - one wire
Attention!
Before starting of the power source you have to
check the output voltages on the STPSP X14 / X15,
4 x 9,6V +/- 10%.
If this voltages are not allright the power module can be
destrojed.
CHANGING OF MAINS VOLTAGE RANGE TO
380 / 415V
