Installation Guidelines

• Mounting: The unit is designed for DIN-rail mounting. Ensure it is secured in a well-ventilated control cabinet to allow for proper heat dissipation.
• Wiring: Connect inputs and outputs using appropriate wire sizes. Since these are solid-state (transistor) outputs, ensure that the connected load does not exceed the maximum current rating specified for the module to prevent internal damage.
• Grounding: Ensure a high-quality connection to the cabinet's protective earth (PE) point to minimize electromagnetic interference and ensure operational safety.
• Power: Verify that the 24V DC supply is stable and properly fused according to your electrical documentation to protect the base unit from power surges.
