“Special conditions for safe use” (only for zone 2 applications)
• The Analogue Data Transmitter type IM31-**Ex-* has to be installed in a suitable housing
according to IEC 60079-15 in such a way, that a degree of protection of at least IP 54 according
to IEC 60529 is reached.
• Using the switches on the front side as well as the connecting and disconnecting of energised
non intrinsically safe circuits is only permitted if no explosion hazardous atmosphere exists.
• For the supply circuit arrangements have to be taken externally, that the rated voltage is
exceeded not more than 40% by transient disturbances.
