 MC-70L and Control Box Combinations

  Only one driver can be connected to the model CB-105 control box. 

  Connect the control box between the power pack and the screwdriver.

 

How to Wire the MC-70L Power Pack

There are two plus-minus pairs of terminals on the back of the power 

pack's case for connection of the trunk-line wires.

Caution

1.  When connecting the trunk-line wire, be sure the red wire goes to 

the plus terminal and the black wire to the minus terminal.

2.  Use no more than the 20 meters of trunk-line wiring provided. A 

longer lead would result in delivery of insufficient voltage that can 

cause driver malfunction.

Connecting procedure

1.  Use U-Element to connect the trunk-line wire to the control box. 

Allow a suitable amount of trunk-line wire, then connect a female 

terminals of branch wire to a male terminals of CB-105, making sure 

both wires are the same color.

2.  Connect the driver's power cord to the control box output connector.

It is recommended that the U-Element (included with the power unit) be 

used to attach a branch wire to the main wire. 

1.  Holding the slot at the bottom of the element open, push the trunk-line wire into the 

groove.

2.  Insert the cut area of the branch wire through the upper hole from the right and push it 

in all the way to the opposite end. 

3.  Use pliers to forcefully push U-Element flat with plastic body.

4.  Snap on the insulation cover.
