Whenever metal cable glands are used in hazardous areas, always
use the grounding tags and connect the wire from those tags to one of
the terminals marked “SHD” on the terminal blocks. This will ground
the exposed metal cable gland.
6.3.4 Transmitter Output, Sensor and Sensor Head Connections
6.3.4.1 Transmitters With Non-Pluggable Terminal Blocks
The following figure shows the layout of the transmitter terminal strip
board. This board is divided into three sections.
The Section#1 terminal blocks are for transmitter outputs. These
signals are not certified non-incendive field wiring.
The Section #2 terminal blocks are for external sensor inputs
(pressure and temperature). These signals are not certified non-
incendive field wiring.
The Section #3 terminal blocks are for the cable interface to the
sensor head. This consists of 12 twisted pairs of conductors plus a
cable drain wire (shield). For Class I, Division 2 rated Transmitter
Model TB8-xx-xx-xx-02 these are to be treated as non-incendive field
wiring.
The recommended torque for the terminal screws is 4.4 to 5.3 lb
f
-inch
(0.5 to 0.6 Nm).
