Model G0820 (Mfd. Since 12/16)
Before the machine can be connected to the
power source, an electrical circuit and connec-
tion device must be prepared per the
POWER
SUPPLY section in this manual; and all previous
setup instructions in this manual must be com-
plete to ensure that the machine has been assem-
bled and installed properly. The disconnect switch
installed by the electrician (as recommended) is
the primary means for disconnecting or connect-
ing the machine to the power source.
Power Connection
Electrocution, fire, shock,
or equipment damage
may occur if machine is
not properly grounded
and connected to power
supply.
Note About Phase Converters: Avoid using a
static phase converter to supply 3-Phase power
for this machine, as it could damage or decrease
the life of sensitive electrical components. If you
must use a phase converter, only use a rotary
phase converter that is sized at least 50% larger
than the largest HP rating of this machine. If
using a phase converter to supply power, only
connect the manufactured leg or "wild wire" to the
"S" terminal (see location
on this page). The S
terminal can handle power fluctuations because it
is wired directly to the motor.
NOTICE
The Model G0820 is prewired for 220V. If
you plan to operate the machine at 440V,
refer to 440V Conversion on Page 16 for
detailed instructions).

4. Make sure wires have enough slack so they
are not pulled tight or stretched.
5. Re-install junction box cover, and perform
