XNX EC Sensor Remote Mounting Kit
The remote sensor mounting kit is used to mount the XNX EC
sensor up to 50 feet away from the transmitter� To mount the
sensor remotely, follow this procedure:
1� Unscrew the weatherproof cover, loosen the retainer
locking screw and unscrew the sensor retainer�
2� Remove the sensor by pulling without twisting�
3� Plug the remote sensor cable connector into the bottom of
the transmitter�
4� Route the cable to the location where the remote sensor is
to be mounted�
5� Optional: make a loop of cable at the junction box� This
will provide some slack for any future re-terminations�
6� If necessary, cut the cable to the required length�
Caution:
Take care not to cut the cable too short. Once cut,
additional lengths of cable cannot be added as this would invalidate
the intrinsically safe certification.
Warning: Enclosures of remotely mounted sensors contain
aluminum. Be careful to avoid ignition hazards due to impact or
friction when installed in Zone 1 locations.
