The 74101-852-53 board kit is a spare part kit that includes a PCB or printed circuit board. It has the alternative catalog number 1336-BDB-SP3D and it is produced by Allen-Bradley as a replacement for faulty gate drive modules in Allen-Bradley 1336 series adjustable frequency drives which belong to the PLUS, FORCE, PLUS II, and IMPACT product lines. Specifically, the 74101-852-53 board is compatible with Series A and up 15 Horsepower rated drives from the 1336 PLUS II series which have an input rating of 460 Volts AC and 15 Horsepower rated drives from the 1336 PLUS, IMPACT, and FORCE series which have input ratings of 460 Volts AC. The drive frame compatible with the 74101-852-53 board kit is Frame B and one kit is needed per drive.

The technicians involved in the repair and maintenance of Allen-Bradley 1336 series AC drives must be familiar with drive systems and associated machinery. Serious injury may result if an oscilloscope and other test equipment are used improperly. Therefore, Allen-Bradley does not recommend the use of an oscilloscope for measuring high voltages. Instead, an isolated measuring device with a high voltage probe should be used. The troubleshooting guidelines and necessary precautions are detailed in the relevant drive manuals from Allen-Bradley. The installation and maintenance of AC drives and accessories like the 74101-852-53 board kit should be performed according to these guidelines while following the recommended precautions. Failure to do so could lead to serious injury or equipment damage. Furthermore, national and local electrical codes should be followed during the installation and maintenance of the AC drives and associated equipment. Equipment damage and injury may occur if these codes are ignored.
