SAFETY NOTICE
Continued
WARNING: If possible, do not adjust trim pots with the main power applied. Electrical shock can cause serious or
fatal injury. If adjustments are made with the main power applied, an insulated adjustment tool must
be used to prevent shock hazard and safety glasses must be worn.
WARNING: Do not use this drive in an explosive environment. An explosion can cause serious or fatal injury.
This drive is not explosion proof.
WARNING: When the Enable jumper is installed, the drive and motor will start and run when AC power is applied,
when power is restored after a momentary power loss, or after an overload or TCL fault is reset. The
user must ensure that automatic start up of the driven equipment will not cause injury to operating
personnel or damage to the driven equipment. The user is responsible for providing suitable audible or
visual alarms or other devices to indicate that the drive may start at any moment. Failure to observe
this warning could result in severe bodily injury or loss of life.
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.
