Instructions For Connection

To The Power Supply

And The Electrical Ground

This machine must be connected to the electrical ground to protect the operator from electric shock. The machine has an approved power cord with two main conductors and one earthing conductor. Connect the plug to a receptacle as shown in Figure 2.

The green (or green and yellow) conductor in the cord is the ground wire. Never connect this wire to any terminal other then the ground terminal.

Make sure you have the correct frequency and voltage before connecting the power cord to an outlet. The machine has a plug as shown in Figure 2. If a receptacle connected to the electrical ground as shown in Figure 2 is not available, have one installed by an electrical contractor. Do not use an adapter.

WARNING: This machine will operate only on AC frequency and electrical voltage shown on the nameplate. Make sure you have the correct frequency and voltage before connecting the power cord to an outlet. If you are not sure, consult your electrical contractor.

WARNING: Have worn, cut or damaged cords and plugs replaced by an authorized service person.

After using this machine, follow these instructions:

-Store the cord on the hook.
