The SP-142507 spare parts kit from Allen-Bradley is specifically designed for the 1336VT Drives series, featuring a main control board ideal for replacing faulty PCBs in these drives. This kit supports drives with power ratings from 3 to 250 horsepower and is compatible with input ratings between 380 to 460 volts AC. Installation requires careful removal of the existing board, with subsequent steps in reverse order for the new board setup, ensuring all connections are properly resecured before restoring power.
