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.

Caution: To prevent equipment damage, be certain that the electrical service is not capable of delivering more than the maximum line short circuit current amperes listed in the appropriate control manual, 240 VAC, 480 VAC or 600 VAC maximum per control rating.

Caution: Before you proceed, be sure to read and become familiar with the safety precautions at the beginning of this manual. If you have any questions, seek expert advise before you proceed. Do not proceed if you are unsure of the safety precautions or any procedure.

Caution: Be sure all packing materials are removed from the board. Conductive foam may be present on the connectors to prevent static build up during shipping. This can prevent proper circuit operation.

Caution: Static electricity damages electrical components. This board has static sensitive components installed. Be sure to comply with ESD (Electro Static Discharge) procedures when handling circuit boards and components.
