SAFETY NOTICE
Continued
WARNING: Do not use start/stop, inhibit or enable functions as a safety disconnect. Use only an AC line disconnect
for that purpose. Failure to observe this warning could result in severe bodily injury or loss of life.
Caution: Disconnect motor leads (A1 and A2) from control before you perform a Dielectric Withstand test on the motor.
Failure to disconnect motor from the control will result in extensive damage to the control. The control is tested
at the factory for high voltage / leakage resistance as part of Underwriter Laboratory requirements.
Caution: Do not connect AC power to the Motor terminals A1 and A2. Connecting AC power to these terminals
may damage the control.
Caution: Baldor recommends not to use Grounded Leg Delta transformer power leads that may create ground
loops. Instead, we recommend using a four wire Wye.
Caution: Suitable for use on a circuit capable of delivering not more than 5,000 RMS symmetrical short circuit
amperes listed here at rated voltage.
Caution: Adjusting the current limit above 150% of the motor nameplate rating can cause overheating and
demagnetization of the PM motor.
Caution: Do not leave the motor in a locked rotor condition for more than a few seconds since motor damage may occur.
Caution: Shunt wound motors may be damaged if field windings remain energized for an extended period of
time without armature rotation.
Receiving
Each control is thoroughly tested at the factory and carefully packaged for shipment.
When you receive your control, there are several things you should do immediately.
1. Observe the condition of the shipping container and report any damage immediately to the
commercial carrier that delivered your control.
2. Verify that the part number you received is the same as the part number listed on your purchase order.
3. Do not unpack until ready for use.
