Control wiring
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. Following best EMC practice and use of
shielded glands is recommended.
Ensure that multi-strand wires are terminated with a crimp suitable to the
wire diameter, (applies to NEMA or SCADA model connections only, not sub-D
connector type terminations). Failure to do so may result in electric shock.
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.
