During a Stop condition, any slight movement of the shaft or magnetic disc could activate the
control relay and start the motor if the Motor Auxiliary, Normally Open Contact (MS Aux n.o.) is
not wired in series. To prevent starting the motor accidentally, always use the proper
LOCKOUT TAG OUT procedures. Failure to observe this warning could result in an injury to
persons or damage to equipment.
