INSTALLATION
Leads and Hoses Track
A means of supporting the leads and hoses from the power supply, water pump, and gas supply to the console
must be provided. In a typical installation, with an X-Y cutting machine, the leads and hoses are carried on a track
down the center or the side of the machine. Several types of these hanging systems are commercially available.
Equipment Supplied and Accessories
Table II (pages 5-10 and 5-11) breaks down what is included in the PAC500 single and two torch systems. A listing
of the required and optional accessories is also included. Although standard lead and hose lengths are specified,
other lengths are available to suit individual requirements. Refer to Section 6 Parts List for additional information.
Installation Instructions
This section outlines, in sequence, the necessary steps to install the PAC500 Plasma Cutting System. Follow these
instructions step by step. Do not skip ahead or do more than one step at a time. When a licensed workman is
needed to do a particular job, such as wiring the power supply to the disconnect box, have the job inspected before
proceeding.
An electrical and plumbing interconnection diagram for the PAC500 Plasma Cutting System is shown in figure 1
(page 5-12).
Control Console
1. Mount the control console on the cutting machine and secure with clamps or screws.
Power Supply
1. Unpack the power supply and insect for shipping damage.
2. Connect a ground strap from the grounding stub mounted inside the power supply to a high quality earth
ground.
3. Connect the leads from the disconnect switch box to the input terminals. Refer to the power supply instruction
manual for more details.
4. Connect a 4/0 welding cable from the positive (+) terminal on the power supply to the cutting table. The cable
clamp must be tightly secured to a clean, oxide free area on the cutting table. A loose connection can cause
operating difficulties. Use two 4/0 cables in parallel if the current exceeds 500 amperes.
5. Connect a 4/0 welding cable from the power supply negative (-) terminal to the 1/2-13X3/4 brass bolt on the
cathode block in the plasma console (refer to figure 7, page 5-17). This cable should be passed through the
1-5/8 bushing (feedthru). Two parallel 4/0 cables should be used if the current exceeds 500 amperes.
