Permitted use
For safety reasons the instrument must be installed and used according to the instruction provided and in particular, under normal conditions, parts
bearing dangerous voltage levels must not be accessible. The device must be adequately protected from water and dust as per the application and
must also only be accessible via the use of tools (with the exception of the frontlet). The device is ideally suited for use on household appliances
and/or similar refrigeration equipment and has been tested with regard to the aspects concerning European reference standards on safety. It is
classified as follows:
• according to its manufacture: as an automatic electronic control device to be incorporated;
• according to its automatic operating features: as a 1 B-type operated control type;
• as a Class A device in relation to the category and structure of the software;
• device with pollution grade 2;
• as a device with class D fire resistance;
• overvoltage category grade II;
• device made with class IIIa material;
Unpermitted use
Any other use other than that permitted is de facto prohibited. It should be noted that the relay contacts provided are of a practical type and
therefore subject to fault. Any protection devices required by product standards or dictated by common sense due to obvious safety reasons should
be applied externally.
