7.2 Grounding

Grounding the positioner is extremely important and highly recommended. Two 
grounding points are provided, one internal and one external. If the cable used 
is shielded, it is recommended that the shield be grounded at one end only. The 
ungrounded end should be carefully isolated.

Figure 7-2 Grounding Screws

Electrical Connection

The PD100 is equipped with screw terminals intended for connection of the control 
signal and feedback signal.

Be sure to supply the rated voltage and current indicated in this manual (see 
Section 2 - Technical Specifications. Failure to do so may cause serious damage or 
malfunctioning of the positioner. Despite the polarity indications, reversing them 
does not alter the positioner’s operation. 

When it is necessary to open the positioner’s cover in a damp place, great care must 
be taken. This may cause serious damage or malfunction of the electronic circuitry. 

 
Before installing the positioner, check the area classification. Never use a General 
Purpose positioner in an area classified as an explosive atmosphere.
