WARNING!
Physical injuries and damage to equipment
Electrical connection errors of the float switches can destroy
the reed contacts. This can lead to a malfunction in the plant
and thus lead to injury to personnel or damage to equipment.
▶
No direct operation in circuits with inductive loads.
▶
No direct operation in circuits with capacitive loads, e.g.
PLC, PCS or cable lengths > 50 m.
▶
Do not exceed the permissible switching power.
DANGER!
Physical injuries
With float switches with connection cable without protective
conductor connection, it is possible for the switch to become
live in the event of a malfunction. Any contact can result in
physical or even fatal injury.
▶
Only operate these switches at safety extra-low voltage
in accordance with IEC 60364 (VDE0100) or fit them
so that the float switch is electrically connected to the
equipotential bonding.
Electrical protection class
Depending on the electrical connection, the instruments are designed
in protection class II. The appropriate protection class of the electrical
connection is given in the respective data sheet.
Protection class II:
Protective insulation, no protective conductor connection
