SECTION 2: CIRCUIT REQUIREMENTS

220V Operation

Serious personal injury could occur if you connect the machine to power before com- pleting the setup process. DO NOT connect the machine to the power until instructed later in this manual.

Electrocution or fire could result if machine is not grounded and installed in compliance with electrical codes. Compliance MUST be verified by a qualified electrician!

Full Load Amperage Draw

This machine draws the following amps under maximum load:

Amp Draw

7.5 Amps

Power Supply Circuit Requirements

You MUST connect your machine to a grounded circuit that is rated for the amperage given below. Never replace a circuit breaker on an existing cir- cuit with one of higher amperage without consult- ing a qualified electrician to ensure compliance with wiring codes. If you are unsure about the wiring codes in your area or you plan to con- nect your machine to a shared circuit, consult a qualified electrician.

Minimum Circuit Size

15 Amps

-10-

Minimum Cord Requirements

For 220V connection, use a stranded-copper flex- ible cord that meets the minimum requirements listed below, does not exceed 50 ft., and has an insulation type that starts with "S." A qualified electrician MUST determine the best cord to use in your environment depending on exposure to moisture, heat, and oils.

Cord Requirements

14/3 AWG, 300VAC

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. We recommend using the plug shown in Figure 2.

Figure 2. NEMA 6-15 plug and receptacle.

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.
