CONDITIONS OF ACCEPTABILITY- For the use as an equipment in type of protection increased safety, and for Zone 2 (EPL Gc), andClass 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.

* The temperature sensor assembly is shown for illustration purpose only.
The remote mount or direct mount sensor, or its assembly with TMT142
is not covered by this certificate.

Applicable requirements see CSA certificate 80047477
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.
