NI Installation instructions
• The transmitter must be installed in an enclosure providing a degree of protection of at least IP54
according to IEC60529 that is suitable for the application and is correctly installed.Cable entry
devices and blanking elements shall fulfill the same requirements.
• If the enclosure is made of non-metallic materials or of painted metal, electrostatic charging shall
be avoided.
• Use supply wires with a rating of at least 5 K above the ambient temperature.
WARNING: Substitution of components may impair suitability for Class I, Division 2
AVERTISSEMENT: la substitution de composants peut nuire à l'aptitude à la Classe I, Division 2.
WARNING: Do not disconnect equipment unless power has been switched off or the area is
known to be safe.
AVERTISSEMENT: Ne débranchez pas l'équipement sauf si l'alimentation a été coupée ou si la
zone est connue pour être sûre.
Non Incendive field wiring installation
The non incendive field Wiring Circuit concept allows interconnection of Nonincendive Field wiring
Apparatus with Associated Nonincendive Field Wiring Apparatus or Assosicated Intrinsically Safe
Apparatus or Associated Apparatus not specially examined in combination as a syatem using any
of the wiring methods permitted for unclassified locations, Voc < Vmax, Ca ≥ Ci + Ccable , La ≥ Li
+ Lcable.
