Installation Notes TMT82- FM Approved Apparatus must be installed in accordance with manufacturer instructions.
- Use supply wires suitable for 5°C above surroundings.
- Only simple apparatus should be terminated to the sensor connection.

Simple apparatus are components as defined by the NEC (1.2 V, 0.1 A, 0.25 mW or 20 µJ).
- Warning: Substitution of components may impair intrinsic safety or suitability for Class I,ATerminal for connecting

INTRINSICALLY SAFENONINCENDIVE, FIELD WIRINGINTRINSICALLY SAFE
IS
Class I / Div. 1 / Groups ABCD
- 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 must meet the following parameters:
Uo £ Ui
Io £ Ii
Po £ Pi
Ca ³ Ci + Ccable La ³ Li + Lcable
Transmitter entity parameters (terminal 1 and 2) are as follows:
Ui or Vmax £ 30 V DC
Ci = 0Ii or Imax £ 130 mA
Li = 0Pi£ 800 mW
- Voc + Voc of Handheld device < Vmax, Isc + Isc of Handheld device < Imax,
Po + Po of Handheld device < Pi, Ca > Ci + Ccable + Ci of Handheld device,
La > Li + Lcable + Li of Handheld device, when Programming Handheld device is used.
NONINCENDIVE
NIClass I / Div. 2 / Groups ABCD
- Depending on location install per National Electrical Code (NEC) using wiring methods describedinarticle 500 through article 510.
Intrinsic safety barrier not required. Vmax £ 35 V DC.
- Warning:
Do not disconnect equipment unless power has been switched off or the area isknown to be non-hazardous.
- Nonincendive field wiring installation
The Nonincendive Field Wiring Circuit Concept allows interconnection of Nonincendive Field
Wiring Apparatus with Associated Nonincendive Field Wiring Apparatus or AssociatedIntrinsically Safe Apparatus or Associated Apparatus not specifically examined in combination asa system using any of the wiring methods permitted for unclassified locations, when Voc £ Vmax,
Ca ³ Ci + Ccable, La ³ Li + Lcable.
Transmitter Nonincendive Field Wiring parameters are as follows:
Ui or Vmax £ 35 V DC
Ci = 0Li = 0Ii or Imax = see following note below
For these current controlled circuits, the parameter Imax is not required and need not to bealigned with parameter Isc and It of the Associated Nonincendive Field Wiring Apparatus or
Associated Apparatus.
