Special Consideration for the Ground Connection
If you choose to make your own cable you must properly ground the cable on both ends to ensure
electromagnetic integrity and compliance with CE regulations. Figure 4 identifies the
components of a cable designed to connect to a Type “D” connector on the pressure switch.

Figure 4: Components of a Cable to Connect to a Type “D” Connector
On the connector end of the cable, Figure 5 shows how the metal braided shield is folded back
over itself to expose the wires. Then the metal shell of the connector is clamped over the metal
braided shield to form a good contact point.
