AB-6600

 To wire between the microswitch and the screw terminals, lay the wires from the terminals to the 

microswitch though the bottom inside of the box.

  Connect the wires to the screw terminals using the round screw terminals (M4 size) as shown in Figure 19.

  Note:  If the wiring was done improperly, the terminal lugs or wires may interfere each other and the terminal cover cannot be attached.

  Note:  Insert the wires through bottom of the terminal cover opening and lay the wires in direction as illustrated by the arrow.

Fit the wires and crimp terminal lugs within this range considering the terminal cover attachment.

  If the knockout hole on the top of box is used, 

lay the wires along the inside wall of the box and 

connect the wires to the microswitch form the 
bottom side.

Example of wiring from the top side of box

Lay the wires along the inside wall of the box and connect the 

wires to the microswitch terminals form the bottom side of the 

terminal cover. Also the opposite side of the box illustrated in 

Figure 20. is applicable.

 Wire to the ground terminal (earth) as shown in 

Figure 21.

 

Note:  Detach the terminal screw and connect the ground 

wire using an insulated round crimping terminal (M4 

size)..

 

Note: Common for Model TY6800Z, TTY6800Z.
