PRECAUTIONS: Classifications of cautionary statements .
WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in injury
or death.
Caution: Indicates a potentially hazardous situation which, if not avoided, could result in
damage to property.
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 it is connected. Electrical shock can cause serious or fatal injury.
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 cause serious or fatal injury.
WARNING: Be sure all wiring complies with the National Electrical Code and all regional and local
codes or CE Compliance. Improper wiring may cause a hazardous condition.
WARNING: Be sure the system is properly grounded before applying power. Do not apply AC
power before you ensure that grounds are connected. Electrical shock can cause serious or fatal
injury.
WARNING: Do not remove cover for at least five (5) minutes after AC power is disconnected to
allow capacitors to discharge. 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 unexpected motor shaft movement will not cause injury to personnel or
damage to equipment. Peak torque of several times the rated motor torque can occur during control
failure.
WARNING: Motor circuit may have high voltage present whenever AC power is applied, even
when motor is not rotating. Electrical shock can cause serious or fatal injury.
WARNING: If a motor is driven mechanically, it may generate hazardous voltages that are
conducted to its power input terminals. The enclosure must be grounded to prevent a possible
shock hazard.
WARNING: When operating a motor with no load coupled to its shaft, remove the shaft key to
prevent injury if it were to fly out when the shaft rotates.
WARNING: The motor shaft will rotate during the autotune procedure. Be certain that unexpected
motor shaft movement will not cause injury to personnel or damage to equipment.
WARNING: A DB Resistor may generate enough heat to ignite combustible materials. To avoid
fire hazard, keep all combustible materials and flammable vapors away from brake resistors.
WARNING: The user must provide an external hard–wired emergency stop circuit to disable the
control in the event of an emergency.
Caution: Suitable for use on a circuit capable of delivering not more than the RMS symmetrical
short circuit amperes listed here at rated voltage.
Horsepower
RMS Symmetrical Amperes
1-50 5,000
Caution: To prevent equipment damage, be certain that the input power has correctly sized
protective devices installed as well as a power disconnect.
