Power Supply

Requirements

Availability

Before installing the machine, consider the availability 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 electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes.

Serious injury could occur if you connect the machine to power before completing the setup process. DO NOT connect to power until instructed later in this manual.

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.

SB1046PF Full-Load Rating	19.23 Amps
SB1047PF Full-Load Rating	19.23 Amps
SB1048PF Full-Load Rating	19.23 Amps
SB1056F Full-Load Rating	19.23 Amps
SB1057F Full-Load Rating	19.23 Amps
SB1058F Full-Load Rating	19.23 Amps

For your own safety and protection of property, consult an electrician if you are unsure about wiring practices or applicable electrical codes.

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 overloading the machine during operation and make sure it is connected to a power supply circuit that meets the requirements in the following section.

Circuit Requirements

This machine is prewired to operate on a 440V power supply circuit that has a verified ground and meets the following requirements:

Nominal Voltage	440V/480V
Cycle	60 Hz
Phase	3-Phase
Circuit Rating	30 Amps

Connection... Hardwire with Locking Switch

A power supply circuit includes all electrical equipment between the main breaker box or fuse panel in your building and the incoming power connections inside the machine. This circuit must be safely sized to handle the full-load current that may be drawn from the machine for an extended period of time. (If this machine is

Note: The circuit requirements in this manual are for a dedicated circuit—where only one machine will be running at a time. If this machine will be connected to a shared circuit where multiple machines will be running at the same time, consult a qualified electrician to ensure the circuit is properly sized.
