the wire. To make the connection, strip about ¼” of the insulation off the wire, and follow the
diagram below.

Insert a small screwdriver into either the hole shown in the diagram.
2.
Insert the stripped end of the wire into the hole shown in the diagram.

Before connecting power to the machine, be sure to check the position of the
voltage selector switch located next to the transformer on the relay board.
Improper positioning of this switch will cause system failure.
