The procedure in Table 15 shows the steps for connecting power to the

 

 

 

transmitter. For loop wiring and external wiring diagrams, refer to the

 

 

 

installation drawings presented in Section 5. Detailed drawings are

 

 

 

provided for transmitter installation in non-intrinsically safe areas and

 

 

 

for intrinsically safe loops in hazardous area locations. If you are using

 

 

 

the transmitter with Honeywell’s TPS system, see the previous TPS

 

 

 

reference.

 

 

 

• All wiring must comply with local codes, regulations, and

 

ATTENTION

 

 

 

 

ordinances.
