Intended use

An EKxxxx Bus Coupler is a control system for use in machine and system engineering for automation, visualization and communication. The EKxxxx Bus Coupler is designed for installation in a control cabinet or terminal box and is used together with Bus or EtherCAT Terminals to receive digital and analog signals from sensors and output them to actuators or forward them to higher-level controllers.

An EKxxxx Bus Coupler has been developed for a working environment that satisfies protection class IP20. This involves finger protection and protection against solid foreign objects up to 12.5 mm, but not protection against water. Operation of the devices in wet and dusty environments is not permitted, unless otherwise specified. The specified limits for electrical and technical data must be adhered to.

Improper use

An EKxxxx Bus Coupler is not suitable for use in the following areas:

• Hazardous area.
• Areas with an aggressive environment, e.g. aggressive gases or chemicals.
• Living areas. In living areas, the relevant standards and guidelines for interference emissions must be adhered to, and the devices must be installed in housings or control boxes with suitable attenuation of shielding.
