The 1797-PSIE comes with a protection factor of IP65. When the power supply outputs have been exposed to non-intrinsically safe signals, the 1797-PSIE, cannot be used in intrinsically safe installations. This module is applicable for installation in Zone 1 where the permissible ambient temperature is f -20…70 °C; Zone 22 that corresponds with the category 3D acc. to directive 94/9 EC and is marked with a type label accordingly. When used with an ambient temperature of 60 Degree Celsius, power supply leads must be designed for service temperature of 80 Degree Celsius.
