-8- Extreme Duty Planers
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).
