Summary, continued

You connect RTD leads to the TC terminals 1, 2, 3, and 4 as appropriate

 

for the given probe type.

 

You connect thermocouple leads to terminals 1 (–) and 3 (+), observing

 

polarity.

 

Each transmitter includes an internal ground terminal to connect the

 

transmitter to earth ground or a ground terminal can be optionally added to

 

the outside of the electronics housing. While it is not necessary to ground

 

the transmitter for proper operation, we suggest that you do so to minimize

 

the possible effects of “noise” on the output signal and provide additional

 

protection against lightning and static discharge damage. Note that

 

grounding may be required to meet optional approval body certification.

 

Refer to section 1.2 CE Conformity (Europe) Notice for special

 

conditions.

 

Transmitters are available with optional lightning protection if they will be

 

used in areas highly susceptible to lightning strikes.

 

Barriers must be installed per manufacturer’s instructions for transmitters

 

to be used in intrinsically safe installations (see control drawing 51404251

 

in Section 13 for additional information).
