1 Safety instructions
1.1 Designated use
The Thermophant®T is a temperature switch for monitoring, displaying and regulating process
temperatures. The device has been safely built with state-of-the-art technology and meets the
applicable requirements and EC Directives. It can, however, be a source of danger if used
incorrectly or for anything other than the designated use.
1.2 Installation, commissioning and operation
Installation, electrical connection, commissioning, operation and maintenance of the measuring
system must be carried out by trained, qualified specialists authorised to perform such work by
the facility's owner-operator. The specialist must have read and understood these Operating In-
structions and must follow the instructions they contain. The device may only be modified and
repair work carried out if this is explicitly permitted in the Operating Instructions. Damaged de-
vices which could be a source of danger may not be commissioned and must be labelled and
identified as defective.
1.3 Operational safety
The measuring device meets the general safety requirements according to EN 61010-1 and the
EMC requirements according to IEC/EN 61326 in addition to the NAMUR recommendations
NE 21, NE 43 and NE 53.
• Functional safety
The Thermophant®T temperature switches were developed according to the standards IEC
61508 and IEC 61511-1 (FDIS). The device version with PNP switch output and additional
analog output is equipped with fault detection and fault prevention facilities within the
electronics and software.
•Ex-area
The Thermophant®T is not approved for use in Ex-areas.
1.4 Return
The following procedures must be carried out before a device is returned to Endress+Hauser:
• Always enclose a fully completed “Declaration of Contamination” form with the device. Only
then can Endress+Hauser transport and examine a returned device. A copy of the “Declara-
tion of Contamination” can be found on the second last page of these Operating Instructions.
• Remove all fluid residues. This is particularly important if the fluid is hazardous to health, e.g.
flammable, toxic, caustic, carcinogenic, etc.
#Warning!
Do not return a measuring device if you are not absolutely certain that all traces of hazardous
substances have been removed, e.g. substances which have penetrated crevices or diffused
through plastic.

2 Device identification
2.1 Nameplate
To identify your device, compare the complete order code and the version information on the
delivery papers with the data on the nameplate.
A0008138
Fig. 1: Nameplate for device identification (as example)
!Note!
The release number indicates the change status of the device. A change in the last two figures
does not have any affect on the compatibility - see also →Chap. 8.
2.2 Certificates and approvals
CE mark, declaration of conformity
On leaving the factory, the device was in perfect condition from the point of view of safety. It
complies with the standards EN 61010 -1 "Protection Measures for Electrical Equipment for
Measurement, Control, Regulation and Laboratory Procedures" and with the EMC requirements
of IEC/EN 61326. The device meets the legal requirements of the EU Directives. The
manufacturer confirms a positive completion of all tests by fitting the unit with a CE mark.
Hygiene standard
The TTR35 temperature switch meets the requirements of Sanitary Standard no. 74-03.
Endress+Hauser confirms this by applying the 3–A symbol (not valid for process connection
conical metal-metal).
