Class I, Division 2 applications, the field transmitter TMT142 shall not be connected or disconnected
unless the area is known to be non-hazardous.
- If the field transmitter TMT142 was used in a Zone 2 (EPL Gc) or Class I, Division 2 application it is
not allowed to use it in Zone 1 (EPL Gb), Zone 0 (EPL Ga) or Class I, Division 1 applications in thefuture.
- Final acceptance of this equipment when installed is subject to the jurisdiction of the local inspection
authority.
- The end user shall ensure appropriate earthing of the metallic field housing upon installation.
- The equipment shall only be powered by limited energy circuits such as Class 2 SELV circuits.

Installation Notes TMT142 (Increased safety/Div. 2 installation with wiring methods)- CSA approved apparatus must be installed in accordance with manufacturer’s instructions.
- Install per Canadian Electrical Code or National Electrical Code (NFPA 70) Wiring methods
for Division 2 or Zone 2.
- Temperature Sensor assembly must be CSA certified for appropriate area classification andtype of protection.
- Use supply wires suitable for 5°C above surroundings.
- Keep tight when circuits alive.
