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.

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.
