2.27 Main Power Input Wiring
Power input to the DMx can be any voltage from 100-230
VAC at 50/60 Hz. For single phase systems, the brown
wire of the seven-wire harness is connected to the Hot
source and the blue wire is connected to the Neutral
source, as shown to the right.
With a three phase supply, the DMx is a single-phase load.
Line voltage is applied using just two wires (Brown and
Blue). Avoid interconnection to power systems that are
not ground-referenced. Choose a connection between a
line (phase) and neutral, connecting the brown wire to
the line and the blue wire to the neutral, following the
illustrations below.
2.28 Detergent Signal Wiring
• Detergent signal input is optically isolated and draws no
more than 20mA.
• It is a universal voltage input that accepts voltage
between 24-250VAC nominal (± 10% fluctuation), or
24VDC nominal (± 20% fluctuation).
• Typical wiring locations are dispenser detergent power
source or the wash motor contacts in the dish machine
control panel. This power source is on when the
dishwasher is running the wash pump.
• Connect yellow (DC+) and white (DC-) colored wires
to detergent signal power source.

2.29 Rinse Signal Wiring
• Rinse signal input is optically isolated and draws no
more than 20mA.
• It is a universal voltage input that accepts voltage
between 24-250VAC nominal (± 10% fluctuation), or
24VDC nominal (± 20% fluctuation).
• Typical wiring locations are dispenser rinse power
source or the rinse solenoid valve circuit in the dish
machine control panel. This power source is live
whenever the dishwasher is rinsing.
• Connect red (DC+) and black (DC-) colored wires to
rinse signal power source.
