Installation Guide 

Shown below are the transmitter display and the field (signal) terminals, located at opposite ends of the 
enclosure. The transmitter enclosure and the display can be rotated for ease of reading regardless of 
transmitter orientation. 
 
An enclosure ground connection is located on the housing beneath the field terminal enclosure cap. The 
enclosure should always be grounded by a wire connected from this terminal to an earth ground, even 
when a ground may be provided by metal conduit protecting the loop wiring.

Rating, Approval, and Tag Plates 

These plates are fastened to the outside of the transmitter 
enclosure, as shown in Figure 7. The rating plate shows that 
transmitter’s model number, serial number, and performance 
data. The approval plate shows that transmitter’s approval and 
certification data. Always refer to these plates to confirm the 
model number, performance data and approval and certification 
data before installing or servicing a transmitter. Representative 
plates are shown in Figure 8. 
 
The tag plate is fastened with two screws so it can be 
removed for engraving.
