Installation Guidelines
-
Mounting: Mount the unit horizontally. Maintain at least 50 mm (2 inches) of clearance on all sides for adequate ventilation, except for the right side where expansion modules are connected.
-
Debris Protection: Keep the protective debris strip on top of the unit during installation to prevent foreign objects from entering the circuitry. Remove only after wiring is complete.
-
Wiring: Ensure all wiring complies with local electrical codes. Disconnect all power before installing or removing expansion modules to prevent electrical damage.
-
Grounding: Proper chassis grounding is essential for electromagnetic compatibility and operational safety.
-
Environment: Install in an enclosure rated for the operating environment. Use climate control (fans or heaters) to maintain the specified operating temperature range.
