Introduction
ELECTRO STATIC DISCHARGE DOES INFLICT IRREPARABLE DAMAGE TO ELECTRONICS! BEFORE INSTALLING OR
OPENING THE UNIT, THE INSTALLER HAS TO DISCHARGE HIMSELF BY TOUCHING A WELL-GROUNDED OBJECT.
THIS UNIT MUST BE INSTALLED IN ACCORDANCE WITH THE EMC GUIDELINES (ELECTRO MAGNETIC COMPATIBILITY).
For installation, pay special attention to:
• Separate cable glands with effective IP67 (NEMA4X) seals for all wires
• Unused cable entries: ensure that you fit IP67 (NEMA4X) plugs to maintain rating
• A reliable ground connection for the sensor
• An effective screened cable for the input signal, and grounding of its screen to terminal 9 (GND) or at the sensor itself,
whichever is appropriate to the application
