Notes for Operation

When using the XN emergency stop switches in safety-related part
of a control system, observe safety standards and regulations of the
relevant country or region. Also be sure to perform a risk assessment
before operation.

Wiring

Tighten the M3 terminal screws to a torque of 0.6 to 1.0 N·m.

Contact Bounce

When the button is reset by pulling or turning, the NC main contacts
will bounce. When pressing the button, the NO monitor contacts will
bounce.
When designing a control circuit, take the contact bounce time into
consideration (reference value: 20 ms).

LED Illuminated Switches

An LED lamp is built into the contact block and cannot be replaced.

Handling

Do not expose the switch to excessive shocks and vibra tions, for
example by operating the switch with tools. Other wise the switch may
be deformed or damaged, causing malfunction or operation failure.
