3.7 Power Supply Output Connections
Refer to Figure 6 and Figure 7 for the physical location of all connections. Remove the
access panel as shown in Figure 6 to begin; replace when installation is complete.
When making brass fitting connections, use two opposing wrenches and only tighten
enough to make water or gas seals. The fittings are subject to damage if over tightened.
Power Supply Electrode Lead
1) Route the 1/2" lug of the Power Supply electrode lead through the opening in
the rear of the Power Supply and connect it using the supplied hardware to
the terminal labelled with the symbol shown. The lug must be installed flat
against the terminal as shown.
2) Route the 5/16" lug of the Power Supply electrode lead through the strain
relief on the ASC. Remove the bolt, lock washer, and ring terminal from the
cathode manifold and install the lug flat against the brass cathode manifold.
Replace the ring terminal, lock washer, and bolt.
Work Ground Lead
3) Route one end of the work ground lead through the opening in the rear of the
Power Supply and connect it with the provided hardware to the terminal
labelled with the symbol shown.
4) Connect the other end of the work ground lead to the star ground point for the
cutting system. Make sure that good metal-to-metal contact is made.
Power Supply Nozzle Lead
5) Route the 1/2" lug of the Power Supply nozzle lead through the opening in the
rear of the Power Supply and connect it using the supplied hardware to the
terminal labelled with the symbol shown.
6) Route the 1/4" lug end of the Power Supply nozzle lead through the strain
relief on the ASC. Connect it to the terminal on the PCB as shown using the
supplied hardware.
Coolant Supply Hose
7) Connect one end of the coolant supply hose to the fitting on the Power Supply
labelled with the symbol shown. The fitting has right hand threads.
8) Connect the other end of the coolant supply hose to the fitting the ASC
labelled with the symbol shown. The fitting has right hand threads.
Coolant Return Hose
9) Connect one end of the coolant return hose to the fitting on the Power Supply
labelled with the symbol shown. The fitting has left hand threads.
10) Connect the other end of the coolant return hose to fitting on the ASC
labelled with the symbol shown. The fitting has left hand threads.
PS Interconnect Cable
11) Connect the PS interconnect cable to the connector labelled P1 on the Power
P1
Supply and to the corresponding connector labelled P1 on the GC.
The Power Supply provides 24VDC to power the GC through this cable. The
24VDC is protected by a 3.5A circuit breaker.
