8.3.3 Disconnecting control supply voltage (U
S
) to safety relay
Switching off the control voltage supply (U
S
) with a controlled motor always results in wear to the electronic
compact starter. This type of switching off should only be used if no more than 10,000 shutdowns can be
expected over the systems entire lifetime.
The safety relay and the electronic compact starter can be connected to the same supply voltage.
It is not necessary to connect to two different supplies.
