cutter allowing an extra two inches of wire between
the motor and the connection points. Strip 1/4" of
wire insulation from the end of each wire. Crimp a
supplied ring tongue connector to the end of each
wire, making sure the wire is fully inserted into the
ring tongue connector. The wire should not stick out of
the connector by more than 1/16 (1.5 mm) of an inch.
Attach the ring tongues to the motor connection points
on the terminal board as described above. Refer to
