WARNING
This document is intended for authorised Smeg technical staff and must be used in combination with the technical
documentation; it describes the power connection conversion procedure.
Only “standard” 400V three-phase units with neutral (400V 3N~ 7.0kW) can be converted on site to the
corresponding 230V single-phase version (230V~ 2.8kW).
The technical data plates of these devices state the two possible electrical connections and the standard configuration
(400V 3N~) is marked with an asterisk.
After the power conversion, tests must be performed to check the appliance's electrical safety and the operation of its
inputs and outputs; the complete “in -service test record” checklist must also compiled (in accordance with the SR
quality procedure).
The illustrations and photographs below are guideline. Always refer to the latest electrical wiring diagram, available at
www.smegtech.com.

3CONVERSION PROCEDURE
WARNING
Before performing any operation, disconnect the device from the electricity and water supplies and make sure that
there is enough space in front of the device - at least 1m2.
ILLUSTRATION
PROCEDURE
1. Remove the bottom door (or "bottom plinth”). Undo
the screws at the sides which secure the bottom door.
2. Disconnect the earth wire fixed to the left-hand corner
of the part and pull the door outward.
3. Remove the "drip guard".
. Undo the fixing screws at the sides
. Lift up the bottom edge of the guard and pull it
outward
4. This gives access to the components on the front cross-
bar;
in particular, you will need to work on:
. power cable
. fuse terminal clamps (for 1160 and 4060)
. wires connecting the fuse terminal clamps to the
power supply terminal board
. power supply terminal board connections
. jumpers on voltage change terminal board

ILLUSTRATION
PROCEDURE
5. On WD4190 and GW4190 you must remove the top of
the device, to access:
.to fuses
.to the mains switch (SZ)
placed in the right-hand side cabinet.
The top is fixed to the machine at the rear by means of
two screws, crosshead.
6. key to main components:
. fuse terminal clamps
. power supply terminal board
. voltage change terminal board “XCT” (configuration
shown is 400 V 3N~)
7. The first component to be replaced (or adapted by
cutting the unused wires) is the power cable.
(PAY ATTENTION: on WD4190 and GW4190 the power
cord is placed in the side cabinet).
If replacement is necessary, proceed as follows:
. Unscrew the fixing screws which secure the terminals at the
end of the cable and release the terminals;
. Connect the new power cable to the old one (still in place)
using adhesive tape;

ILLUSTRATION
PROCEDURE
. Loosen the cable gland on the rear cross-bar and pull the
whole of the old cable out of the back of the appliance;
. Leave about 30 cm of the new cable (including the stripped
part) on the front cross-bar to allow the contacts to be restored;
. Connect the terminals of the new power cable to the fuse
terminal clamps and connect the earth wire to the power supply
terminal board (check that if the cable is pulled, the earth wire
is always the last one to become taut).
Front view MAINS SWITCH “SZ”
8. On WD4190 and GW4190 only, the power cord is
housed in the side cabinet and ends within the
terminals of the mains switch "SZ".
Apply the same prescriptions as above.
Rear view
9. On WD4190 and GW4190: it is necessary to act on the
mains switch TERMINALS ("Mains Switch"):
maintaining, in the case of single-phase, only the
phase L1 and the neutral N.
The adjacent images: front and rear view of the mains
switch. On 0160, 1160, 4060 models, the electric switch is
not installed.
10. Use the fuse holder - power supply terminal board connection wires to create the configuration required,
checking it using the electrical wiring diagram and a tester.
. 400V 3N~ - three-phase 400V with neutral
. FUSES 16 A
In this configuration, the neutral is connected directly to
the terminal board and not to the fuse holder.
. 230V 1N~ - single-phase 230V
. FUSES 16 A
In this configuration, the neutral is connected to the fuse
holder.
11. Modify the power supply terminal board to create the electrical configuration required, as shown in the

electrical wiring diagram.
400V 3N~ - three-phase 400V with neutral
wiring side:
. connection of L1, L2, L3, N as shown on connection data
plate.
230V 1N~ - single-phase 230V
wiring side:
. L1 and L3 connected to the same terminal clamp: L1
. L2 and N connect to the same terminal clamp
12. Move the jumpers on the voltage change terminal board (“XCT” in the diagram) to create the power
connection required.
a. 400V 3N~ - three-phase 400V with neutral
The tank heating elements are star-connected (the
jumpers form the centre of the star).
b. 230V 1N~ - single-phase 230V

PROCEDURE
13. Final check on connections
. Check that the connections made are mechanically and electrically secure.
. Use the tester to check the connections made and that they correspond to the electrical wiring diagram.
14. Close the appliance:
. Perform the tests to check the appliance's safety
following the company procedure.
. Supply electricity to the appliance.
. Use the technical application to check that the device's
inputs and outputs function correctly.
. Set the type of connection (3=three-phase, 1=single-
phase) in the SET-UP menu, following the procedure
provided in the user manual.
. Perform a complete wash cycle including operation of
the heating elements, to check that the appliance
functions correctly.
