Connecting Power Cord to Lathe

Electrocution or death will occur if you attempt this procedure with the power cord connected to the power source. The cord must be disconnected from power before performing this procedure.

These instructions are for setups where the lathe will be connected to the power source with a power cord and plug, as opposed to a hardwire setup.

To connect power cord to the lathe:

1.Unlock and open the main electrical cabinet door, and install a strain relief in the location shown in Figure 14.

2.Thread the power cord through the strain relief, and up to the main power switch shown in Figure 14.

3.Connect the incoming L1, L2, L3 and ground wires to the main power switch terminals, as illustrated in Figure 15.

4.Make sure the cord/wires have loose slack between the strain relief and terminal connections, then tighten the strain relief to secure the power cord.

Note: The strain relief must be tightened against the outermost jacket of the cord. Avoid over- tightening the strain relief or it may crush the cord and cause a short.

5.Test the strain relief to ensure it is properly tightened by pulling the cord from outside the box with light-to-moderate force. When the strain relief is properly tightened, the cord will not slide.

6.Close and lock the main electrical box door.

Hardwiring Lathe to Power Source

Hardwire setups require power supply lines to be enclosed inside of conduit, which is securely mounted and constructed in adherence to applicable electrical codes.

A hardwire setup for this machine must be equipped with a locking disconnect switch as a means to disconnect the power during adjustments or maintenance, which is a typical requirement for lock-out/tag-out safety programs (commonly required by OSHA).

Figure 16 shows a simple diagram of a hardwire setup with a locking disconnect switch between the power source and the machine.
