A hazard of personal injury from automatic restart exists
with 2-wire control. 2-wire control uses maintained Run
contacts that act as both Run (closed) and Stop (open)
devices. Opening the Stop contact (terminal 20) will stop
the drive. If this contact is reclosed, any fault will be reset.
If a valid Start command is still present, the drive will
restart. Only use 2-wire control for applications outlined in
NFPA79, "Under Voltage Protection."
If a 3-wire device (i.e. HIM) is also used, pressing the HIM
Stop key will also stop the drive. Releasing the Stop key
will clear any faults that are present, but the drive will not
restart without cycling the Start contact.
