Support cables at appropriate intervals. Where possible, use cable trays.
•
NOTE: For EMC reasons (interference rejection and surge handling), all of the cable trays carrying signal cables
should be electrically continuous (i.e. the sections should be interconnected by heavy-gauge electrical
wiring) and they should be connected to Earth at multiple points along their length. Cable trays are
typically secured to grounded metal structures, which satisfies this requirement.
The cable screen must be terminated correctly.
•
Any unused cable glands must be blanked using an appropriate device.
•
When connecting the sensor, the 4 off screws securing the enclosure cover lid should be coated with a small
•
amount of copper grease before refitting and securing the lid. Do not over-tighten the screws.

5.3 MOUNTING THE SENSOR

5.3.1 Safety Information

CAUTION! – PROBE DAMAGE
Take care when handling the sensor to avoid bending or damaging the probe. Probe damage may result
in inaccurate measurements.
CAUTION!
Do NOT try to rotate the sensor by twisting its enclosure as this can seriously damage the sensor.
