7.0Electrical 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 JWL-1440VS Lathe is rated at 115/230V power, and is pre-wired for 115 volt. The lathe comes with a plug designed for use on a circuit with a grounded outlet that looks similar to the one pictured in A, Figure 8.

Before connecting to power source, be sure switch is in off position.

It is recommended that the lathe, when operated on 115 volt power, be connected to a dedicated 20 amp circuit with a 20 amp circuit breaker or time-delay fuse marked “D”. When operated on 230 volt power, it is recommended that the lathe be connected to a dedicated 15 amp circuit with a 15 amp circuit breaker or time-delay fuse marked “D”. Local codes take precedence over recommendations.

7.1Grounding instructions

1. All Grounded, Cord-connected Tools:

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. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.

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. Failure to comply may cause serious or fatal injury.

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug.

Repair or replace damaged or worn cord immediately.

2.Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating less than 150 volts:

This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in A, Figure

8.An adapter, shown in B and C, may be used to connect this plug to a 2-pole receptacle as shown in B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. This adapter is not permitted in Canada. The green-colored rigid ear, lug, and the like, extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box.

3.Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating between 150 - 250 volts, inclusive:

This tool is intended for use on a circuit that has an outlet that looks like the one illustrated in D, Figure

8.The tool has a grounding plug that looks like the plug illustrated in D. Make sure the tool is connected to an outlet having the same configuration as the plug. No adapter is available or should be used with this tool. If the tool must be reconnected for use on a different type of electric circuit, the reconnection should be made by qualified service personnel; and after reconnection, the tool should comply with all local codes and ordinances.

7.2Voltage conversion

To switch the incoming power leads for 230 volt operation:

1.Remove the junction box cover on the motor and reconnect the leads according to the diagram inside the cover. A similar diagram is found at the back of this manual. (Note: In the event of discrepancies, the diagram inside junction box takes precedence.)

2.Remove the 120V plug on the end of the motor cord and replace it with a UL/CSA listed plug rated for 240V.
