INSTALLATION PROCEDURES 3-2 Manual 0-2844
3.05 Primary Input Power
Connections
The CE CutMaster TM Power Supply operates on three
phase, 400VAC (± 10%), input power.
CAUTION
The primary power source and power cable must
conform to local electrical code and the recom-
mended circuit protection and wiring requirements
(refer to table in Appendix 1).
The Power Supply is equipped with a three-phase, four
conductor, input EMC power cable attached. Connect
the cable to the customer's power source as follows:
NOTE
The input power cable must not be modified in any
way as filtering beads are installed on the cable.
1. The outer covering of the cable is stripped back
approximately 3 inches (76 mm) at the factory to
expose the individual wires at the free end of the
cable.
2. Cut back the insulation on the individual wires
approximately 1/8 - 3/16 inch (3-5 mm).
3. Connect the ends of the individual wires to a cus-
tomer supplied plug or main disconnect per the
following:
NOTE
All the input cable wires must be connected for
three-phase operation.
• Blue wire to Line 2 (Live)
• Black wire to Line 3 (Live), refer to Note above
• Brown wire to Line 1 (Live)
• Green/Yellow wire to Ground (Earth)
4. (CE CutMaster 75, CE CutMaster 100 only): Con-
nect a customer-supplied grounding cable to the
grounding stud on the rear panel as required by
applicable Local and National Codes or local au-
thority having jurisdiction. Grounding stud is
identified with this symbol:
5. Connect the input power cable (or close the main
disconnect switch) to supply power to the system.

B. Checking Air Quality
To test the quality of air, place the RUN/SET switch to
SET position, place a welding filter lens in front of the
torch and turn on the gas. Any oil or moisture in the air
will be visible on the lens. Do not initiate an arc!
CAUTION
Air supply must be free of oil, moisture, and other
contaminants. Excessive oil and moisture may
cause double-arcing, rapid tip wear, or even com-
plete torch failure. Contaminants may cause poor
cutting performance and rapid electrode wear.
