Electrical connection
of the liquid soap supply system
The power supply of the liquid soap supply system has to be connected to an external electrical source.
Only authorized workers with a valid qualification must execute the electrical connection on the machine
according to the valid local standards. The correct connection way can be found on the wiring diagram
that is located inside the cabinet in a plastic bag. Do not connect the liquid soap pump system in the
washer.
For electric connection of supply control signals is available on the back side of the machine the terminal
box with LED signalization of activation of the respective pump, see figure 26, pos.3. At the terminal box
there is a label for electric connection. Detail connection of signals could be also found on the electric
scheme of the machine. Signals for supply pumps control are 24V AC. Maximum current for control circuits
of pumps must be limited to 10mA. Lead the cable for connection of pumps control signals through the plastic
cable bushing, pos.2. After connection of conductors to the respective positions of the connector “P”
(screw clamps), fix up the cable by tightening the cable bushing against disconnection and close the box
with the cover. For details about liquid soap supply system programming, see Programming manual.
