Remote models without relay modules
Interfacing the pump with other devices is by means of two IP66 rated five pole M12
connectors mounted on the front of the pump. M12 connectors with flying lead cables can
be purchased as an accessory from Watson-Marlow. The function of each of the leads is
labelled.

It is the user’s responsibility to ensure the safe and reliable operation of the pump under
remote and automatic control.
Never apply mains power to the five pole M12 connectors. Apply the
correct signals to the pins, as shown below. Limit signals to the
maximum values shown. Do not apply voltage across other terminals.
Permanent damage may result.
All input and output terminals are separated from mains circuits by
reinforced insulation. These terminals must only be connected to
external circuits that are also separated from mains voltages by
reinforced insulation as a minimum requirement.
