Electrical protection class
Depending on the electrical connection, the instruments are designed
in protection class II. The appropriate protection class of the electrical
EN
connection is given in the respective data sheet.
Protection class II:
Protective insulation, no protective conductor connection
Connection with inductive load
With inductive loads, the float switches should be protected by
connection to an RC element or a free-wheeling diode.
