Installing The Sensor; Safety Information - Pentair Goyen Mecair FFA Installation And Operation Manual

Where a cable run approaches the instrument from above, it must be run underneath the instrument and then
•
curved up to the cable gland.
Where a cable enters a cable gland, sufficient slack should be left in the cable so that a new connection can
•
be made if needed.
Leave sufficient slack in the sensor cable to allow the sensor unit to be removed and placed on the ground
•
or platform for servicing.
Support cables at appropriate intervals. Where possible, use cable trays.
•
NOTE: For EMC reasons (interference rejection and surge handling), all 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 requireme
The cable screen must be terminated correctly.
•
Any unused cable entry glands must be blanked using the appropriate device (one of the cable glands is blanked
•
ex works, see Figure 1 on page 5).
When connecting the unit, the screws securing the cover lid should be lightly coated with copper grease before
•
refitting and securing the lid. Do not over-tighten the screws.

6.3 INSTALLING THE SENSOR

6.3.1 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.
CAUTION!
Ensure that the sensor unit is only ever connected to the dedicated FFA control unit.
