When the temperature switch is mounted, the temperature must
neither drop below the allowed operating temperature (environment,
medium) nor exceed it, even when taking convection and heat
radiation into account.
Depending on the type of application, the electrical connection must
be protected from mechanical damage.

6.2 Electrical connection

Cables and wires
Leads with bare ends must be finished with end splices.
■
Cables used must comply with the respective requirements in
■
terms of stability and temperature.
Connecting cables must be run so that any mechanical damage is
■
prevented.
Only connect circuits with the same voltage and type of protection
■
to the switch contacts and connecting cables.
