protection (at least IP54).

 The device may only be operated in environments not exceeding degree of pollution 2.

 In hazardous areas, operate the rotary switch of the device only in a de-energised state.

 The connections on the signal circuits are provided for connection to low-energy electrical

circuits and equipment (IEC/EN 60079-15 ch. 13). Otherwise, external measures must be

implemented in order to prevent the rated voltage being exceeded by more than 40%.
