INSTALLATION and SETTING
The Vacuum switch must be installed preferably in a vertical position with electrical connection upwards. The Vacuum switch can be damaged in the presence of impacts and high vibrations creating false contacts. The Vacuum switches have no protection, can be protected with caps and connectors. The degree of protection can be IP 54 or IP65, depending on the type (IP 67 special versions). On request, special, already wired, Vacuum switches are manufactured, with body in acc. stainless steel, degreased for use with oxygen, gold contacts for low currents. Our technical office is available for the most suitable solution for your application. Particular attention to the external environment in which the Vacuum switches are installed. do not use the standard models in environments where there is a flammable atmosphere due to the presence of gas or other contaminations that could make the use dangerous. In these cases use the explosion-proof or protected versions. Our technical office is available to recommend the most suitable solution.
