■ Activation switch
In the wiring diagrams, the activation switch has the designation [K]. This represents a
component such as a manually operated switch, an emergency stop push button switch, or
the contacts of a safety relay or safety PLC.
• In case a manually operated activation switch is used, the switch must be of a type that
can be locked out to the open position.
