Do not remove or dismantle a pressurized controller! Removing or dismantling a pressurized prestage or spool valve of an ND9300H leads to uncontrolled pressure release. Always shut off the supply air and release the pressure from the pipelines and equip- ment before removing or dismantling the controller.
Attach the bracket (1) to the actuator. The shaft meets the IP66 protection class according to EN 60529 coupling of the ND9300H must fit into the ear (2) in any position when the cable entry is plugged accord- so that the pointer is located in the position ing to IP66.
