Handling Precautions

This section provides handling precautions for the EtherCAT Slave Unit.
• Always turn OFF the Controller before you mount or dismount a Unit or connect or disconnect cables.
• Provide separate conduits or ducts for the I/O lines to prevent noise from high-tension lines or power
lines.
• Prevent wire clippings, cutting chips or other materials from getting inside the Unit. They could cause
scorching, failure, and malfunction. Pay particular attention to this during installation and take mea-
sures such as covering with a cover.
