Electrical connection (PROFIBUS PA)

ATTENTION!

During the electrical connection of the inherently safe circuits, always observe the

data in the attached Certificate of Conformity!

Use screened cable for connecting the bus and the binary input in order to assure reliability and EC

conformity. The cable screens can be attached using the clamping screw (on the post between the M20

bushings). The cable screens must be attached at both ends. On the outside of the housing there is a

further screw for further connection to a suitable earthing (grounding) point.

To make electrical connections, open the cover of the SIDE Control

(PROFIBUS PA) by

unscrewing the 2 screws.
