Snapping the switch onto a grounded rail connects it to the
ground potential. In an environment particularly prone to EMI,
noise immunity can be increased through the additional
ground connections on the power connector.
Alarm contacts
FL SWITCH 300 switch provides contacts (R1 and R2) to
provide an external alarm in the event of a failure. If either
power supply fails (≤12V) or a port fails (LNK), the internal dry
contacts close.
This device is designed for SELV and PELV
operation according to IEC 61140/EN 61140.
