Site Requirements

In This Section, You'll Learn:

About the site requirements of this machine (including electrical and power requirements).

Before operating the machine in any way, you must read and understand this section.

General Site and Space Requirements

When choosing a location for your machine, you must verify that it meets all requirements outlined in this section.

Site Requirements

You must verify that the area:

• Allows for unrestricted access to machine controls.

• Conforms to the following:

  • Primary Power Required Single-Phase 115 Vac, 50/60 Hz

  • Recommended Circuit Amperage Dedicated 15 A breaker

NOTE: For more information, see "Electrical and Power Requirements".

• Has clean, dry, compressed air.

• Has one continuous slab sufficient to support the weight of the machine, accessories, and any additional equipment.

• Is a dry, properly ventilated, and well-lit internal space that conforms to the following temperature and humidity requirements:

  • Operating Temperature Range 40°F-100°F (5°C-38°C)

  • Humidity Range 5%-95% (non-condensing)

• Provides for unobstructed machine motion and operation.

Space Requirements

The area must meet the following space requirements. Allow more space to access the rear of the machine for maintenance and repairs.

• Machine Size 42" × 36" (1.1 m × 0.9 m)

• Machine Height 72" (1.8 m)

Typical System Footprint 62" × 52" (1.6 m × 1.3 mm)

Electrical and Power Requirements

You must verify that the site conforms to the following electrical and power requirements.

Electrical Requirements

A certified electrician must make all electrical connections, and it's your responsibility to verify that the electrical installation of the machine meets all local regulations and electrical codes.

• Primary Power Required Single-Phase 115 Vac, 50/60 Hz

• Recommended Circuit Amperage Dedicated 15 A breaker

Power Requirements

If the site conforms to the electrical requirements, verify that it meets the following power requirements:

• No Electrical Noise Primary power must be provided by a dedicated circuit, which must be isolated from electrically-noisy devices like welders or plasma torches. The machine should be isolated from inductive loads from items like vacuum cleaners or air compressors.

• No Ground Fault Circuit Interrupter Power for the machine must not be protected by a ground fault circuit interrupter (GFCI), as it interferes with the operation of the variable frequency drive (VFD) spindle controller.

• Proper Grounding You must properly ground the power input to the machine. Examine the continuity between bare metal on the machine frame and true earth ground (a water pipe or similar) to verify that it's properly grounded.

• Correct Plug Pattern The machine is shipped with a NEMA 5-15P plug, designed for use with a NEMA 5-15R receptacle.

Options for Non-Conforming Sites

For sites that don't conform to the specified "Electrical and Power Requirements" (page 4), you may consider the following. You must consult with an electrician to determine the suitability for your site.

Step-Down Transformer Used at sites where 115 Vac service is not possible. You must make sure that the step-down transformer has sufficient capacity to supply the machine, accessories, and any 115 Vac auxiliary equipment. We recommend the Step-Up/Step-Down Transformer (PN 32009).
