Electrical Connections, Grounding Instructions

Electrical Connections

Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

The Jointer is equipped with either a single phase, 230 volt motor; or a three phase, 230/460 volt motor. The single phase unit is factory wired for 230 volts. You may either install a UL/CSA listed plug suitable for 230 volt operation, or “hard-wire” the jointer directly to a service panel. The circuit for the machine should be a dedicated circuit.

The three phase motor is pre-wired for 230 volt. It may be re-connected for 460 volts by changing the connections as illustrated in the diagram in the motor wiring box (see “Converting from 230 Volt to 460 Volt”). You may either install a UL/CSA listed plug suitable for the specific voltage, or “hard-wire” the jointer directly to a service panel.

If the jointer is to be hard-wired to a panel, make sure a disconnect is available for the operator. During hard-wiring of the machine, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the jointer will be connected. Place a warning placard on the fuse holder or circuit breaker to prevent it being turned on while the machine is being wired.

Grounding Instructions

This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.

Improper connection of the equipment- grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes, is the equipment- grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Repair or replace a damaged or worn cord immediately.
