Requirements

SMKDSP1.5/2-5.08 Phoenix Contact

• Two core shielded cable

• Cable outer diameter: 0.35˝ to 0.47˝ 9-12mm

(Required for correct installation with Cable

Gland option)

• Wire Gauge: 14-22 AWG (multi-strand or solid)

Note:

• When transporting and / or mounting do not apply excessive shock

or use device as a step.

• The piping should be of proper length so as not to apply load to the

connection point on the transmitter.

• At the time of mounting or when bleeding air from the device be sure

to open the equalizing valve with a flathead screwdriver so that ex-

cessive pressure (more than the allowable maximum differential pres-

sure) is not applied to the differential pressure sensor. Maximum torque

to apply to equalizer valve is 0.75 ft-lbs ±5%.

7. WIRING

7.1 Cable/Wire Specifications

Use appropriate cable described below which is suitable for power

supply requirements and ground to housing.

7.2. Wiring Instructions

• To reduce potential for noise do not run pressure transmitter cable /

wires alongside (same conduit as) high voltage (line power) lines.

For optimum results use dedicated conduit for GC52 cable / wires.

• If using the Cable Gland termination option must use cable within

previously noted diameters to maintain environmental ratings.

• When connecting shield / drain wire, only connect one end which

should be at the receiver ground.

• Wiring stripping instructions, remove cable jacket 2-3˝ and strip wires

±0.25˝. Shield / drain wire should not be exposed at the pressure

transmitter termination.

• Remove cover and carefully remove the display to access the termi-

nal strip, take care not to mishandle the display and associated elec-

tronics.
