How to Use Gearheads

Before Using an AC Motor or Gearmotor

Motor Connection

Lead Wire for Power Supply
For power supply, use a thicker lead wire than the motor lead wire.
Motor frame size: 1.64 inch (42mm): AWG 24
Motor frame size: 2.36 inch (‚0mm) or larger: AWG 20

Motors with Terminal Boxes

World K Series 6W Type

	Inside Terminal Box	Recommended crimp terminals
Compact, light weight and in-line arrangement of terminal blocks for ease of connection.

Installing Terminal Box
	When installing the terminal box, be sure to use a rubber gasket in order to maintain a tight seal. Cable entry is possible at any of the four sides of the terminal box. Undo the screws which attach the terminal box to the motor case, position the terminal box so that the outlet faces in the desired direction and refasten the screws.

World K Series 25W ~ 90W Type V Series, BH Series and BHF 200W
The material of the terminal box is PBT resin with excellent insulation performance. Also, a terminal block which is certified by European safety standards are utilized. *When connecting cables to the terminal block, loosen the screw on the insertion port for the lead wire and insert the lead wire with a screw driver. Then tighten the screw securely.

Conduit Box Type

Conduit Type Box is available for induction motors.

Open the terminal box and connect the wires.
Use applicable cable ground and conduit for conduit opening.
After connecting, close the terminal box with the terminal cover.

How to Connect a Capacitor
Note: When motors are running, a voltage of almost twice the motor power supply voltage is applied across the terminals of the capacitor. The terminals must therefore be insulated to ensure safety. Use the capacitor cap provided to insulate the terminals.

2-terminal type		4-terminal type

		For lead wire connection with 4-terminal capacitor, use one lead wire per terminal.

Grounding

Lead Wire Type and Terminal Box for 6W Type
Any one of the four mounting bolts may be used to attach the ground wire to the motor case when installing the unit. If necessary, remove all paint that may impede conductivity around the bolt mounting hole.

World K Series, V Series and BH Series			Conduit Box Type
Connect the ground wire to the ground terminal inside the terminal box.			Conduit box mounted motors have a ground lead wire (green wire). Connect the ground wire to this green lead wire.

Contact Capacity
Connect a CR circuit (surge suppressor) like that in the drawing in order to protect the contacts.
