Installation
 The RS 485-IS coupler should be installed inside the hazardous area of the hazardous area (zone 2)
in a suitable housing that provides at least IP 54 protection. The ambient conditions also have to be
taken into account. There must be a manufacturer's declaration for zone 2 available for the housing
(in accordance with EN 60079-15).
 If a temperature of > 70 °C is reached in the cable or at the cable entry of this housing under
operating conditions, or if a temperature of > 80 °C can be reached at the junction of the conductors
under operating conditions, the temperature-related properties of the cables must correspond to the
temperatures actually measured.
Commissioning
 Only field devices which are certified for the PROFIBUS RS 485-IS interface may be connected to the
RS 485-IS coupler.
