For Class I, Zone 2, ATEX rated Transmitter Model TB8-xx-xx-xx-03
these are to be treated as non-incendive field wiring.
6.3.4.5 Sensor Head to Transmitter Cable Connections (Section #3)
The sensor head to transmitter cable is used to transmit sensor data
and information between the transmitter and the sensor head, and
provides power to the electronics mounted in the sensor cover.
Note: The armored cable is equipped with a shield wire on the
supplied cable gland nut. This shield wire is connected to any of the
SHD terminals in Section #3 of the terminal board.
The sensor head to transmitter cable is furnished with a connector
attached to the sensor head end. The transmitter end is cut to length
and terminated at installation.
The connector on the sensor head end of the cable will be one of two
similar-looking connectors but of noticeably different size. The two
connector types are not interchangeable. The cable delivered with the
passive sonar meter should have a connector which is matched to the
one on the sensor head.
The sensor head to transmitter cable can be either run in cable trays
or through conduit in accordance with local practice.
Sensor Head End Cable Attachment - Once the cable is run, attach
the connector on the sensor cable end to the mating connector on the
sensor cover. Align the keyway on the sensor connector and latch in
place.
Transmitter End Cable Attachment - Note: Each wire pair may be
numbered on the white wire only. Care should be taken to ensure the
black non-numbered conductor stays matched with its numbered
white conductor.
CAUTION
Ensure each numbered white conductor and its corresponding
black conductor remain as a set to ensure proper operation of
the meter.
WARNING
For Class I, Division 2 applications, the SENSOR HEAD TO
TRANSMITTER CABLE must be installed in accordance with
National Electrical Code requirements for Non-incendive circuits.
