Power Supply Output Connections
Perform the following steps to connect the output of the power supply to the impulse
start console and the work table. See Figure 4 on the next page.
Power Supply Electrode Lead
1. Route one end of the #1/0AWG power supply electrode lead through the upper
strain relief on the rear of the power supply and connect it to the electrode terminal.
2. Route the other end of the power supply electrode lead through the strain relief on
the impulse start console and connect it to the cathode manifold.
Power Supply Nozzle Lead
1. Route the larger ring terminal end of the #10AWG power supply nozzle lead through
the bushing on the rear of the power supply and connect it to the nozzle terminal.
2. Route the smaller ring terminal end of the power supply nozzle lead through the
strain relief on the impulse start console and connect it to the pilot terminal on the
printed circuit board.
Power Supply CTP Sensor Lead
1. Route the ring terminal end of the #14AWG power supply CTP sensor lead through
the bushing on the rear of the power supply and connect it to the CTP terminal.
2. Route the FASTON end of the power supply CTP sensor lead through the strain
relief on the impulse start console and connect it to the CTP sensor lead with
FASTON connector.
Work Ground Lead
1. Route one end of the #1/0AWG work ground lead through the bottom strain relief on
the rear of the power supply and connect it to the work terminal.
2. Connect the other end of the work ground lead to the star ground point on the cutting
table.
The star ground point is generally referred to as the common ground point on the
cutting table where all subsystems of the machine are grounded. This point is then
connected to a driven earth ground rod that should be as close as possible to the
star ground. The ground rod should have no other wires connected to it. The
ground rod should be at least 3/4 inches in diameter and should be driven into the
earth’s permanent moisture layer. The length of the ground rod varies from
installation to installation and should be installed according to local and national
codes. Refer to the National Electrical Code, Article 250, Section H, Ground
Electrode System for additional information.
