Rewire to 440V

The Model G9740/G9740Z/G9741/G9961 can be rewired from 220V to 440V. Before rewir- ing, purchase the Grizzly 440V conversion kit (#P97400120-11).

Please Note—The Model G9967/G9967Z cannot be rewired to 440V.

The 440V wiring conversion procedure requires rewiring the transformer, installing new overload relays for the feed and elevation motors, setting all the overload relay dials to the correct position, and rewiring the motors.

To rewire the planer:

1.Open the control panel so that you have access to the electronic components inside.

2.On the transformer, move the wire that is connected to the “220” terminal to the “440” terminal.

3.Remove the old feed motor relay and install the RHN-18 (1.7-2.5A) relay in its place.

4.Set the dial on the new relay to 2A.

5.Remove the old elevation motor relay and install the RHN-18 (1-1.7A) relay in its place.

6.Set the dial to 1A.

7.At the main motor overload relay (5-60A), set dial to the following amperage, depending on

your machine:
• G9740/G9740Z	10A
• G9741/G9961	13A

8.Change the wiring on all three motor terminal boxes to match the diagram on the inside of the terminal box cap (use the wiring diagram pages in the “Reference Info” section at the back of this manual if the diagram is missing from the inside of the cap).
