2. 2 Certificates and approvals
CE mark, declaration of conformity
The devices are designed and tested to meet state-of-the-art safety requirements in accordance
with sound engineering practice. They have left the factory in a condition in which they are safe
to operate. The devices comply 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 described in these Operating
Instructions is therefore in conformity with the statutory requirements of the EU Directives. The

Hygiene standard
The TTR35 temperature switch meets the requirements of Sanitary Standard no. 74-03.
