WARNING: Do not touch any circuit board, power device or electrical connection before you
first ensure that power has been disconnected and there is no high voltage present from this
equipment or other equipment to which itis connected. Electrical shock can cause serious or fatal
injury. Only qualified personnel should attempt the start-up procedure or troubleshoot this
equipment.

WARNING: Be sure that you are completely familiar with the safe operation of this equipment.
This equipment may be connected to other machines that have rotating parts or parts that are
controlled by this equipment. Improper use can causeserious or fatal injury. Only qualified
personnel should attempt the start-up procedure or troubleshoot this equipment.
WARNING: Do not use motor overload relays with an automatic reset feature. These are
dangerous since the process may injure someone if a sudden or unexpected automatic restart
occurs. If manual reset relays are not available, disable the automatic restart feature using externalcontrol wiring.

WARNING: Do not remove cover for at least five (5) minutes after AC power is disconnected
to allow capacitors to discharge. Dangerous voltages are present inside the equipment. Electrical
shock can cause serious or fatal injury.
WARNING: Improper operation of control may cause violent motion of the motor shaft and driven
equipment. Be certain that unexpectedmotor shaft movement will not cause injury to personnel
or damage to equipment. Certain failure modes of the control can produce peak torque of several
times the rated motor torque.
