Grounding Instructions
In the event of a malfunction or breakdown,
grounding provides a path of least resistance
for electrical current to reduce the risk of electric
shock. A permanently connected machine must
be connected to a grounded metal permanent wir-
ing system; or to a system having an equipment-
grounding conductor. All grounds must be verified
and rated for the electrical requirements of the
machine. Improper grounding can increase the
risk of electric shock!
Serious injury could occur if you connect
machine to power before completing setup
process. DO NOT connect to power until
instructed later in this manual.
Connection Type
A permanently connected (hardwired) power sup-
ply is typically installed with wires running through
mounted and secured conduit. A disconnecting
means, such as a locking switch (see following
figure), must be provided to allow the machine
to be disconnected (isolated) from the power
supply when required. This installation must be
performed by an electrician in accordance with all
applicable electrical codes and ordinances.

Extension Cords
Since this machine must be permanently con-
nected to the power supply, an extension cord
cannot be used.
Voltage Conversion
The voltage conversion MUST be performed by
a qualified electrician. To perform the voltage
conversion, rewire the motors to the new voltage,
according to the provided wiring diagram. If the
diagram included on the motor conflicts with the
one in this manual, the motor may have changed
since the manual was printed. Use the diagram
provided on the motor.
Note About 3-Phase Power: DO NOT use a
static phase converter to create 3-phase power—
it can quickly decrease the life of electrical com-
ponents on this machine. If you must use a phase
converter, only use a rotary phase converter.
You can find the Model G7978, a compati-
ble phase converter from on our website at
www.grizzly.com.
G7978—15 HP Rotary Phase Converter
This rotary phase converter allows you to operate
3-phase machinery from a single-phase power
source at 100% power and 95% efficiency.
