Safety Notice | This equipment contains voltages that may be as high as 600 volts! Electrical shock can |
| cause serious or fatal injury. Only qualified personnel should attempt the |
| procedure or troubleshoot this equipment. |
| This equipment may be connected to other machines that have rotating parts or parts |
| that are driven by this equipment. Improper use can cause serious or fatal injury. Only |
| qualified personnel should attempt the |
PRECAUTIONS
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. Only qualified personnel should attempt the
WARNING: Be sure the system is properly grounded before applying power. Do not apply AC power before you ensure that all grounding instructions have been followed. Electrical shock can cause serious or fatal injury.
Caution: | Install MOV protection for the control. See Appendix D for information. | |
Caution: | Do not remove keypad cable with power applied to unit. Disconnecting the keypad | |
| cable with power applied will damage the control. | |
Caution: | Shearpin trip feature is not equivalent to short circuit overcurrent protection | |
| required by NEC. Instantaneous overcurrent protection must be provided by | |
| circuit interrupting device (fuse or breaker). | |
Caution: | Suitable for use on a circuit capable of delivering not more than the RMS | |
| symmetrical short circuit amperes listed here at rated voltage (with fuses specified | |
| in Section 2). |
|
| Rated Amperes | RMS Symmetrical Amperes |
| 5,000 | |
| 10,000 | |
| 18,000 | |
| 30,000 | |
| 42,000 | |
Caution: | Do not “Megger” test the motor while it is connected to the | |
| Failure to disconnect motor 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. Do not megger any part of the control. | |
Caution: | Do not connect power factor correction capacitors to motor terminals. If power | |
| factor correction capacitors are necessary, contact Baldor. | |
Caution: | If a brake motor is used, the initial starting voltage may not be sufficient to release | |
| the brake. It may be necessary to provide separate power for the brake release | |
| coil. |
|
Caution: | Do not connect AC incoming line power to the Motor terminals T1, T2 and T3. | |
| Connecting AC power to these terminals may result in damage to the control. | |
