4. Mains Voltage Selection (only to be carried out by a qualified service technician)
After adjusting the mains voltage, operating the DPP 4004/4012 power supplies with 115 V is also
possible.
The adjustment has to be carried out before the operation:
- Remove the cover plate.
- Insert the flat wire bridge on the printed board assembly 86245 into the 115V~ position (red
conductor).
- With the DPP 4004 additional switching of a switch-mode power supply is necessary. The
correspondent switch is located inside the switch-mode power supply (see yellow label). Remove
the front panel (4 screws). Using a suitable screwdriver (size 1), the mains voltage selector
switch which is located behind the perforated coverage – has to be set to the 115V~ position.
A silvery label stating different voltages is located on the right inside of the enclosure. After switching
the appliance to 115V operation, the corresponding label has to be removed and attached to the rear
panel, so that it covers the imprinted marking 230V~ below the mains connector.
The following only applies to the DPP4012:
Exchanging the mains fuses to operate the appliance with 115 V ~ AC:
- Replace the mains fuse (T2,5A/H for 230 V operation) located in the fuse socket (5) with a
T5A-type fuse. The label on the rear panel T2,5A/H which is located below the fuse socket (5) has to
be replaced by the T5A-label.
Lock the top cover plate and the front panel in place.
