Installation Guidelines

• Secure the EtherCAT Box using its integrated mounting points on a flat, stable surface.
• Ensure all M8 and D-sub connectors are properly seated and tightened to maintain the IP65/66/67 protection rating.
• Use shielded EtherCAT cables for communication to comply with EMC standards (EN 61000-6-2/EN 61000-6-4).
• The module supports downstream power connection via an M8 female socket; ensure total current requirements do not exceed limits.
• Operate within the specified ambient temperature range of -25 to +60 degC to avoid performance degradation.
