4.04 Control Box Installation
Determine where the Control Box should be located in relationship to where the gouging will take place. It is not
recommended to carry the Control Box on any travel system other than the Victor Arcair Titan ® Machine Carriage
due to the added weight of the Control Box and the weight of the power cables coming from the DC Power Supply.
The Control Box can be secured to a stationary surface with the mounting brackets on both sides. Refer to "Table
3-2: Control Box Features" on page 3-2 for the mounting brackets and "Figure 3-4: RIGHT Side of Control Box"
and "Figure 3-5: BACK of Control Box" on page 3-3 for bracket locations.
NOTE
DO NOT force connections. All connectors should be fastened easily. Be sure to tighten connections
as you go through each step. Avoid crimping hoses or wires.
WARNING
Select the receptacle voltage that correctly matches the plug and power requirements of the Carriage
System.
WARNING
Confirm that the Power Supply and Control Box Power In switches are OFF.
