• For ambient temperatures higher than +70 °C, use suitable heat-

resisting cables or wires, cable entries and sealing facilities for Ta =

+5 K above surrounding.

• The maximum diameter of external lead wire is 1.5 mm

 stranded

and solid.

• The creepage distance and clearances of 3 mm for terminals are to be

upheld after external wiring.

WARNING

Explosive atmosphere

‣

In an explosive atmosphere, do not open the device when voltage is

supplied (ensure that the IP 66/67 housing protection is maintained

during operation).

Safety

instructions:

Special conditions

• The temperature of the enclosure shall not 100 °C.

• Install the sensor, type TTSP, in temperature assemblies with

terminal head and extension parts, which shall have a degree of

protection of at least IP54 in compliance with EN/IEC 60079-0 and

EN/IEC 60079-7 and its ultimate application.

• For assure that the temperature assembly has a degree of protection

of at least IP54 the user has to provide a thermowell or equivalent

component at the process side.

• Sensors are to be mechanically protected by thermowell.

• The thermometer must be installed and maintained 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.
