Converting Voltage To 440V - Grizzly G0866 Owner's Manual

Converting Voltage
to 440V
The Model G0866 is prewired to operate on
220V power, but it can be converted for 440V
operation using the optional conversion kit (Model
G440VG0866), which contains two replacement
overload relays. 440V conversion consists of:
1) disconnecting the machine from the power
source, 2) moving a wire on the transformer from
the 220V to the 440V terminal, 3) replacing the
main and feed motor overload relays, and 4)
rewiring the motors for 440V operation. Wiring
diagrams are provided in the back of this manual
beginning on Page 75 showing the Model G0866
wired for both 220V and 440V. Refer to these
when following this procedure.
All wiring changes must be done by an electri-
cian or qualified service personnel. If, at any time
during this procedure assistance is needed, call
Grizzly Tech Support at (570) 546-9663.
