Control wiring
13.1
Upper D-connector
Recommended control cable: 7/0.2mm 24AWG screened. Cable screen should be earthed with a 360 deg
connection to a conductive back- shell. This will be connected to pump mains EARTH via the D connector
body. Mains Earth is also available on pin 1 Upper D and pin 13 Lower D.
13.2
Lower D-connector
The 0V of this pump is DC isolated (floating) from the pump mains Earth. However, do not allow pump 0V to
exceed 10V from the pump mains earth through connection with remote equipment, to avoid overstressing
internal 0V to Earth EMI capacitors.
Never apply mains power to the D-connectors. Apply the correct
signals to the pins shown. Limit signals to the maximum values
shown. Do not apply voltage across other pins. Permanent damage,
not covered by warranty, may result.
Keep 4-20mA and low voltage signals separate from mains power.
Use separate glanded input cables.
Ensure that multi strand wires are terminated with a crimp, suitable
for the wire diameter. Failure to do so may result in electric shock.
