  • Page 4: General Information

    GENERAL INFORMATION Thank you for selecting a Bodine Type ABL Encased Brushless DC Motor Control. Your new control will provide the same excellent performance and reliability that have been a Bodine tradition since 1905. Bodine Electric Company takes pride in the quality of its products and in satisfying its customers.
  • Page 5: Specifications

    A built-in shutdown circuit disables the control during over-voltage, under-voltage, or invalid commutation sensor state conditions. Specific Bodine motor sizes which can be used with these controls are listed in the Chart in Figure 3.
  • Page 6: Important Safety Precautions

    Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture and intended use of the products. Bodine Electric Company assumes no liability for the customer’s failure to comply with safety requirements and practices.
  • Page 7 Check the items you received against your purchase order. Carefully examine the control (and any optional kits or parts) for shipping damage. Parts errors should be reported to Bodine. Shipping damage claims should be made to the freight carrier. Before installation, review the application to confirm that the proper motor and control have been selected.
  • Page 8 Do not insert anything into a product’s ventilation openings. Servicing Emergency field repairs must be made only by authorized Bodine service representatives. Repairs made by persons not authorized by the Bodine Electric Company will void the warranty. Field repairs must be limited to replacing an entire printed circuit board assembly.
