5 Wiring
!CAUTION
►Switch off power supply before installing or connecting the device. Failure to observe this
may result in destruction of parts of the electronics.
►When installing Ex-approved devices in a hazardous area, please take special note of the
instructions and connection schematics in the respective Ex documentation added to these
