SECTION 2: CIRCUIT REQUIREMENTS

220/440V Operation

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.

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 G0646/G0647 is prewired for 220V operation. If you plan to use your machine at 440V, you MUST have a quali- fied electrician perform the 440V conver- sion described on Page 13.

Power Supply Circuit Requirements

You MUST connect your machine to a grounded circuit that is rated for the amperage given below. Never replace a circuit breaker on an existing cir- cuit with one of higher amperage without consult- ing a qualified electrician to ensure compliance 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, consult a qualified electri- cian.

NOTICE

Phase Converter Precaution

The power from the manufactured leg of a phase converter may damage electrical components if connected to the wrong incoming power terminal on your machine. Only connect the manufactured leg to the T3 terminal of the main power switch (see Page 53 for identification).

NOTICE

Extension Cords (220V Only)

Using extension cords may reduce the life of the motor. Instead, place the machine near a power source. If you must use an extension cord:

•Use at least a 12 gauge cord that does not exceed 50 feet in length.

•Ensure that the extension cord contains a ground wire and plug pin.
