Intended use

The embedded PC is a control system for use in machine and system engineering for automation, visualization and communication. The embedded PC 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.

The Embedded PC is designed for a working environment that meets the requirements of 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 specified otherwise. The specified limits for electrical and technical data must be adhered to.

In hazardous areas

Device modification CX2900-0107 is mandatory for operation of the embedded PC in hazardous areas, zone 2/22. The device modification includes a factory-installed retainer bracket for mechanically securing the connectors.

The device modification is mandatory for operating the embedded PC in the following hazardous areas:

1. For zone 2 atmospheres in which gas is present as a combustible material. Zone 2 means that an explosive atmosphere does usually not occur during normal operation, or only for a short time.
2. For zone 22 atmospheres in which dust is present as a combustible material. Zone 22 means that an explosive atmosphere in the form of a cloud does usually not occur during normal operation, or only for a short time.

The embedded PC must be installed in a housing, which ensures protection rating IP54 for gas according to EN 60079-15. A housing with protection rating IP54 is required for non-conductive dust. IP6X is required for conductive dust according to EN 60079-31.

Improper use

The embedded PC is not suitable for operation in the following areas:

• In hazardous areas, the embedded PC may not be used in other zones except for 2/22 and not without a suitable housing.
• 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.
