(1) Safety feedback function: restarting is possible only if the power contactors K1 and K2 are at rest.
(2) Voltage suppressor adapted to the voltage and contactor type. Increases the life of contacts S1 and S2 and limits the interface emissions.
(3) This contactor arrangement is implemented to avoid short circuits on the safety wires. If used with a 24 VDC configuration, K1 must be connected to the common line.
