Installation Guidelines

Ensure the entire control system is safely powered down and isolated from electrical energy before performing any mechanical or electrical work.
Inspect the BECKHOFF EL3612 terminal housing and connection points for any signs of transit damage.
Mount the terminal onto a standard 35 mm DIN rail conforming to EN 60715, ensuring the locking mechanism engages securely.
Connect field sensors to the appropriate terminal points using solid or stranded conductors with proper stripping lengths and ferrule use where required.
Verify that all signal wiring and shield connections adhere to local electrical codes and EMC requirements.
Power on the EtherCAT network and verify proper diagnostic LED operation through the TwinCAT engineering environment before initiating normal system operation.
