WARNING! Electrical installation should be completed by a qualified electrician.
All local and national electrical regulations are to be observed.
Conductivity Probe Wiring
Although the conductivity probe wiring is pre-wired to the controller, you
must make the connection to the probe installed on the washer.
1) Route the probe wires to the conductivity probe location and cut to fit if
required.
2) Strip the wire ends and crimp on the ring terminals provided.
3) Connect ring terminals to each of the probe connections, sandwiching
each ring terminal between the nuts and washers provided (as shown at
right). Ensure all connections are tight and secure.
Main Power Input Wiring
Power input to the EvoWash can be any voltage from 100-240 VAC
at 50/60 Hz. For single phase systems, the brown wire of the six-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 EvoWash 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.
Main Power Input Wiring: Three Phase AC Power
Note! An accessible
neutral is required.
Connect between line
and neutral ONLY.
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 24-249VAC
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 w/yellow (DC-) colored wires to
detergent signal power source.
Rinse Signal Wiring (Optional)
WARNING! If a rinse pump is not installed, cap off
and insulate the unused rinse signal wires.
•
Rinse signal input is optically isolated and draws no more
than 20mA.wires to detergent signal power source.
•
It is a universal voltage input that accepts voltage between 24-249VAC 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 purple (DC+) and white w/purple (DC-) colored wires to detergent signal power source.
