1 Introduction 1.2 Application Thermostats are used to control and monitor thermal processes. Panel-mounting thermostats operate according to the fluid or gas expansion principle. The electrical switching element is a micro switch. The devices of the EM type series are available as safety -temperature monitors STW and safety temperature limiters STB. In the event of a malfunction, the STB switches the monitored machine line to an operational safe status.
1 Introduction 1.4 Safety information H Filling fluid can emerge in the event of a measuring system break. A hazard to health is excluded as per the present information. Physical and toxic features of the expansion means, which could emerge in the event of a measuring system break: Control range with scale limit value °C Hazardous reaction < +200 Fire and explosion hazard Ignition temperature °C Explosion limit Vol.% no +355 0.

3 Installation 3.3 Capillary / temperature probe / sheath 3.3.1 General information A Bending/kinking or cutting the capillary of the panel-mounting thermostats will lead to a permanent device failure! The minimum admissible bending radius of the capillary is 5 mm. The temperature probe must be installed in JUMO sheaths, otherwise, the approval of the panel-mounting thermostats will become null and void. Ensure that the temperature probe is completely submerged in the medium to be measured.

3 Installation A Design 10, 15, 21, 60, 65: only use in pressureless medium. H Ensure that the temperature probe (2) is completely submerged in the medium because otherwise, greater switching point deviations will occur. For connection types 20, 21 and 22, the temperature probe is fixed in the sheath with the clamping piece ( 1 ).
4 Installation 4.1 Standards and information ■ Only allow electricians to carry out the electrical connection. ■ The choice of cable, the installation and the electrical connection of the device must conform to the requirements of VDE 0100 "Regulations on the Installation of Power Circuits with Nominal Voltages below 1000 V" and/or the appropriate local regulations. ■ If contact with live parts is possible while working on the device, it must be completely isolated from the supply.
