Notes on Wiring
Crimping Terminals
• When using crimping terminals, be sure to use insulated terminals to prevent electric
shocks.
Without Crimping Terminals
• Insert the wire until the insulation comes into contact with the terminal metal part.
• Strip the insulation so that the wire is longer than the width of the wire clamp.
• When connecting two wires, use wires of the same length.
• To prevent damage, ensure to use plain washers when installing.
