Power Connection Device

The type of plug required to connect your machine to power depends on the type of service you cur- rently have or plan to install. For 220V single- phase operation we recommend using the plug shown in Figure 2. For 220V three-phase opera- tion we recommend using the locking disconnect switch shown in Figure 3.

Extension Cords

Using extension cords may reduce the life of the motor. Instead, place the machine near a power source. If you must use an extension cord:

Use at least a 14 gauge cord that does not exceed 50 feet in length!

The extension cord must also have a ground wire and plug pin.

A qualified electrician MUST size cords over 50 feet long to prevent motor damage.
