To implement selective shutdown of one single motor starter, use a fail-safe F-DQ device or
the signal of a fail-safe sensor. The motor connected to the motor starter is shut down with a
direct connection of fail-safe sensors on the BaseUnit (BU30-MS6).
The sensor connected to the fail-safe digital input on the motor starter's BaseUnit requires
the same ground potential as the ground connection "M" on the motor starter's BaseUnit.
