8.4.1 Transmitter Housing Cable Entry
Power, sensor signal, and input /output signal cables enter the
transmitter housing through cable glands. The cable glands also
provide strain relief for the cables. Always ensure they are fully
tightened. The following figure illustrates where each of the cable
glands are installed.
Figure 32 Transmitter Housing Cable Gland Holes
Note: On those transmitters installed in Class I Division 2 areas,
cable glands rated for NEMA 4X (minimum rating) must be used. Any
unused cable gland holes must be sealed with NEMA 4X rated hole
plugs. Also, the four cover sealing screws on the transmitter cover
must be securely tightened in order to ensure a proper seal.
