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.
