Terminal Strip
Cable
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.
