Page 10: Mounting
VEGATOR 636 Ex signal conditioning instrument with plug-in socket for mounting on carrier rail according to EN 50022. Transparent cover The front plate of VEGATOR 636 Ex can be provided with a lead-seal- able transparent cover to protect the instrument against unauthorised or inadvertent adjustment. See the following figure on how to remove the transparent cover. - Page 11 The plug-in socket is provided with coded pins that can be inserted to prevent accidental interchanging of the various instrument types. With a VEGATOR 636 Ex in Ex version, the supplied coded pins (type coded pin and Ex coded pin) must be inserted by the user according to the below chart.
