Connection methods
Wire modification
• Remove insulation from wire attached to wire kit connector.
• Remove insulation from locally purchased cable. Use crimp type insulated butt
connector to join field cable and wire kit wire.
• Connect the wire with connecting wire with solder.
IMPORTANT: Be sure to insulate the connection between the wires.
Locally purchased
External connect kit (option)
Solder and insulate the connected parts.
