FM approved Associated Apparatus
or supply with suitable barrier

Installation Notes TM411, TM412- FM approved apparatus must be installed in accordance with manufacturer’s instructions.
- Install per temperature transmitter’s control drawing when supplied with transmitter.
- Warning: Substitution of components may impair suitability for Class I, Division 2.
- Warning: The thermometer must be installed so, that even in the event of rare incidents, an ignition source due
to impact or friction between the enclosure and iron/steel is excluded.

- Installation should be in accordance with ANSI/ISA RP 12.6.01 “Installation of Intrinsically safe
systems for Hazardous (classified) locations” and the National Electrical Code (ANSI/NFPA 70).
- FM approved associated apparatus or barrier is required.

NONINCENDIVENIClass I / Div. 2 / Groups ABCD
- Depending on location install per National Electrical Code (NEC) using wiring methods described inarticle 500 through article 510.
- Intrinsic safety barrier not required.
- Warning: Do not disconnect equipment unless power has been switched off or the area is known to be nonhazardous.
- Nonincendive field wiring installation
The Nonincendive Field Wiring Circuit Concept allows interconnection of Nonincendive Field Wiring Apparatus
with Associated Nonincendive Field Wiring Apparatus or Associated Intrinsically Safe Apparatus or AssociatedApparatus not specifically examined in combination as a system using any of the wiring methods permitted for
unclassified locations, when Voc £ Vmax, Ca ³ Ci + Ccable, La ³ Li + Lcable.
For transmitter’s or sensor’s Nonincendive Field Wiring parameters see parameters below.
For these current controlled circuits, the parameter Imax is not required and need not to be aligned withparameter Isc and It of the Associated Nonincendive Field Wiring Apparatus or Associated Apparatus.
(* The head transmitter TMT180 is only suitable for Class I, Division 2.
