Wiring	Wiring and power supply requirements can be dependent upon the approval
	certification. As with all FOUNDATION fieldbus requirements, a conditioned
	power supply and terminating resistors are required for proper operation. The
	standard 2051 pressure transmitter terminal block is pictured in Figure 2-13.
	The terminals are not polarity sensitive. The transmitter requires 9-32 Vdc to
	operate. Type A FOUNDATION fieldbus wiring 18 awg twisted shielded pair is
	recommended.
	Avoid running instrument cable next to power cables in cable trays or near
	heavy electrical equipment.

It is important that the instrument cable shield:

•be trimmed close and insulated from touching the transmitter housing

•be connected to the next shield if cable is routed through a junction box

•be connected to a good earth ground at the power supply end

Do not connect the power signal wiring to the test terminals. Voltage may burn out the reverse-polarity protection diode in the test connection.
