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.
