screws.

C. Machine Systems (Shielded Leads)
Systems ordered with Shielded Machine Torch will in-
clude a Computer Control (CNC) Control Cable. The
CNC Control Cable allows the Power Supply to interface
with a computer or other control device.
NOTE
Refer to Appendix 5 for CNC Control Cable Inter-
face Signal Diagram.
Connect the CNC Control Cable and Torch Leads to the
Power Supply as follows:
1. Open the Access Panel to gain access to the Torch
Bulkhead Panel.
2. Remove the hardware attached to the power sup-
ply end of the leads assembly with a tie wrap.
3. Feed the connector on the end of the CNC Control
Cable through the rubber boot on the front panel of
the Power Supply (see NOTE).
NOTE
Feed the Control Cable through the rubber boot first
as there will not be enough space inside the rubber
boot for the connector if the Coolant and Gas Leads
have been fed through the rubber boot first.
4. Connect the CNC Control Cable connector to the
Control Cable connector on the Torch Bulkhead
Panel.
5. Feed the end of the Torch Leads through the rubber
boot.
6. Refer to the illustration. The Leads Assembly in-
cludes two leads shields; each shield includes two
ring-tongue connectors. Connect the Torch Leads
Shield Wires as follows:
a. Remove one nut and star washer from the torch
leads shield stud on the Torch Bulkhead Panel.
b. Place the ring lugs from the inner (RED) Torch
Leads Shield Wires over the shield stud on the
Torch Bulkhead Panel.

the wires to the shield stud on the power sup-
ply chassis.
