Power Supply Circuit Requirements
The power supply circuit for your machine MUST
be grounded and rated for the amperage given
below. Never replace a circuit breaker on an exist-
ing circuit with one of higher amperage without
consulting a qualified electrician to ensure compli-
ance with wiring codes.
If you are unsure about
the wiring codes in your area or you plan to
connect your machine to a shared circuit, con-
sult a qualified electrician.
Minimum Circuit Size (220V) .................50 Amps
Minimum Circuit Size (440V) .................30 Amps
Serious personal injury could occur if you
connect the machine to the power source
before you have completed the setup pro-
cess. DO NOT connect the machine to the
power source until instructed after setup.
220/440V Operation
Electrocution or fire could
result if this machine is
not installed to code. You
MUST ensure compliance
by checking with a quali-
fied electrician!
NOTICE
The Model G0677 is prewired for 220V oper-
ation. If you plan to use your machine at
440V, you MUST have a qualified electrician
perform the 440V conversion described on
Page 12.
Minimum Cord Requirements
For 220V or 440V connection, an electrician
MUST hardwire the machine. The electrician who
hardwires the machine will determine the appro-
priate wire to use inside the conduit.
Phase Converter Precaution
We do not recommend using a static phase con-
verter with this machine. If you must use a phase
converter, use a rotary-type phase converter.
When using a phase converter, the power from the
manufactured power leg can fluctuate. Connect
the manufactured power leg to the T terminal (see
Page 63) to prevent damage to the transformer.
The wire from the T terminal can handle some
fluctuation because it goes directly to the motor.
The power going to the R and S terminals goes to
the transformer and must be consistent to prevent
damage to electrical components.
