G0450 at 440V

 

Power Connection

 

 

 

 

 

 

Serious personal injury could occur if you connect your machine to the power source before you have completed the set up pro- cess. DO NOT connect the machine to the power source until instructed to do so.

220V Pre-Wired

The Model G0450 is prewired for 220V 3-phase operation, but can be rewired for 440V 3-phase operation if needed.

Amperage Draw

The Model G0450 has a 15 HP motor that will draw the following amps at 440V 3-phase:

Main Motor at 440V

............................... 20

Amps

Feed Motor at 440V

............................ 0.65

Amps

Circuit Requirements

Only connect your machine to a circuit that meets the requirements below. Always check to see if the wires and circuit breaker in your circuit are capable of handling the amperage draw from your machine, as well as any other machines that could be operating on the same circuit. If you are unsure, consult a qualified electrician.

Minimum Circuit Requirement 440V

30 Amp

Minimum Cord Requirements

A cord is not provided with your machine. For 440V 3-phase operation, use the following type of cord (not to exceed 50 ft.):

Cord

4 wire

Gauge

8 Gauge

A fire may occur if your particular electrical configuration does not comply with local and state codes. The best way to ensure compli- ance is to check with your local municipality or a qualified electrician.

Because of the high amperage draw from this machine, we recommend that you hardwire it directly to your circuit breaker and install a locking shut-off lever (see Figure 3) near the machine as a way to quickly disconnect the power and pre- vent accidental starting.

Figure 3. A power disconnect is preferable to

high current plugs and receptacles.

Phase Converter

with G0450

When using a phase converter, the power from the manufactured power leg (sometimes called the wild wire) can fluctuate. Connect the manu- factured power leg to the L2 terminal to prevent damage to the transformer. The wire from the L2 terminal can handle some fluctuation because it goes directly to the motor. The power going to the L1 and L3 terminals goes to the controls and must be consistent to prevent damage.
