8.4.1 Disconnecting control input voltage (R and L) to safety relay
In applications where the emergency stop is a normal operation status, such as two-hand applications or
safety doors, the control current circuit (R and L) is switched instead of the control voltage. If possible, use
this circuit example in order to achieve the maximum lifespan.
Switching off the control supply voltage with a controlled motor always results in wear to the electronic
compact starter.
The safety relay and the electronic compact starter can be connected to the same supply. It is not necessary
to connect to two different supplies.
