NOTE
When a system contains paralleled Unidrive SPMC/Us, the rectifier's
status outputs must be daisy chained to the status inputs of the next.
Providing the system is fused correctly, the method used to monitor the
rectifier status must have the ability to disable the system within 500ms.
A PLC can be used to monitor the status output of the rectifier. PLC input
impedance must be no greater than 10kΩ. Status signals are not
latched.
