SECTION 2: POWER SUPPLY

Availability

Before installing the machine, consider the avail- ability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocu- tion, fire, or equipment damage, installation work and electrical wiring must be done by a qualified electrician in accordance with all applicable codes and standards.

Electrocution, fire, or equipment damage may occur if machine is not correctly grounded and connected to the power supply.

Full-Load Current Rating

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

G0453 Full-Load
Current Rating at 220V	15 Amps
G0454 Full-Load
Current Rating at 220V	25 Amps

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid over- loading the machine during operation and make sure it is connected to a power supply circuit that meets the requirements in the following section.

G0453 220V Circuit Requirements

This machine is prewired to operate on a 220V power supply circuit that has a verified ground and meets the following requirements:

Nominal Voltage		220V/240V
Cycle		60 Hz
Phase		1-Phase
Circuit Rating		20 Amps
Plug/Receptacle		NEMA 6-20
Cord	3-Wire, 12 AWG, 300VAC, “S”-Type

G0454 220V Circuit Requirements

This machine is prewired to operate on a 220V power supply circuit that has a verified ground and meets the following requirements:

Nominal Voltage		220V/240V
Cycle		60 Hz
Phase		1-Phase
Circuit Rating		30 Amps
Plug/Receptacle		NEMA L6-30
Cord	3-Wire, 12 AWG, 300VAC, “S”-Type

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power sup- ply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

For your own safety and protection of property, consult a qualified electrician if you are unsure about wiring practices or electrical codes in your area.

Note: The circuit requirements listed in this man- ual apply to a dedicated circuit—where only one machine will be running at a time. If this machine will be connected to a shared circuit where mul- tiple machines will be running at the same time, consult a qualified electrician to ensure that the circuit is properly sized for safe operation.
