SB1041 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
Cycle	60 Hz
Phase	3-Phase
Circuit Rating	15 Amps
Plug/Receptacle Type	Hardwire

Grounding Requirements

In the event of certain types of malfunctions or breakdowns, grounding provides a path of least resistance for electric current—in order to reduce the risk of electric shock.

For 110V Connection (SB1040 Prewired)

This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug (similar to the figure below). The plug must only be inserted into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances.

For 220V 1-Phase Connection (SB1040)

Use the plug type listed in the Circuit Requirements for this voltage. The listed plug (similar to the figure below) has an equipment- grounding wire to safely ground the machine. The plug must only be inserted into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances.
