3.05 Filling Master Power Supply
Coolant
NOTE
Only the Master Power Supply requires coolant.
DO NOT install coolant in the Slave Power Sup-
ply or the second Master Power Supply if used.
The ambient temperature of the environment where the
Power Supply will be located determines the coolant to
be used. The Standard Torch Coolant supplied with the
system can be used in ambient temperatures down to 10° F
(-12° C).
Optional Super Torch Coolant should be used in areas
where the ambient temperature drops down to -27° F (-33° C).
CAUTION
Use only Thermal Arc Torch Coolant. Use of any
other coolant can result in torch damage, insuffi-
cient thermal protection, and/or pilot arc interfer-
ence.
1. Locate the coolant deionizer bag and remove from
the plastic shipping bag.
2. Remove the coolant filler cap from the reservoir at the
top rear of the Power Supply.
3. Place the deionizer bag into the basket in the coolant
reservoir.

4. Carefully pour enough of the supplied Thermal Arc
Torch Coolant into the reservoir to fill it to the FULL
mark on the rear panel.
NOTE
After operating the system more coolant may need
to be added. Allow the pump to operate for ten
minutes to properly purge any air from the coolant
lines before using the system.
5. Reinstall the reservoir coolant filler cap.
3.06 Input Power Connections
The Power Supply accepts input voltages from 200V to
575V, 50 or 60 Hz, three-phase power. Every Power Sup-
ply is factory wired for 460V input. For any other input
voltage, the Power Supply must be reset.
NOTE
Refer to Section 3.07, Voltage Selection.
A. Electrical Connections
The power source must conform to local electric code and
the recommended circuit protection and wiring require-
ments shown in Appendix 1.
