INSTALLATION AND OPERATION MANUAL – OWNER'S RECORD PEM MANUAL – PARTICULATE EMISSION MONITOR
•
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
.
