Installation Guidelines

• Mounting: Ensure the unit is mounted on a flat, vibration-free surface within an enclosure that meets the required ingress protection standards for your environment.
• Cooling: Maintain adequate clearance around the unit to allow for natural convection cooling; avoid mounting above heat-generating equipment.
• Wiring: Keep input and output signal wiring separate from high-voltage power lines to minimize electromagnetic interference (EMI). Use shielded cables for analog or high-speed input signals if applicable.
• Grounding: Connect the protective earth terminal to a common ground point to ensure noise immunity and electrical safety.
• Polarity: Verify the correct DC voltage polarity before applying power to the controller to prevent permanent damage to the internal circuitry.
