• 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 exceed +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.
