2.2 Assembly Instructions

This section has step-by-step instructions on how to assemble the AMC-AMP-50A-EVM. Lugs come secured by default, but if the user needs to reattach during evaluation, follow step number one below.

  1. Connect the high-current input lugs to the IN+ and IN- pads with the supplied screw and hexnut.
    1. The lugs must not touch when secured.
    2. Make sure that the lugs are positioned such that the lugs make contact with the maximum amount of surface area of the PCB pad.
    3. The connectors must be tightly fastened to the current carrying cables such that the connectors can not be moved by hand. A torque wrench is recommended to provide symmetrical connection. A torque of approximately 40in-lbs is recommended.
  2. Solder additional shunt resistor if desired. See Section 3 for more information on shunt limitations.
  3. Modify isolated comparator adjustable trip threshold resistor (R20) if desired. The default trip voltage is ±72A. Refer to the AMC23C15 data sheet for more information.
