Power Connection
The Powermax1650 is a universal power supply that configures itself to operate with AC voltages from 200 to 600
3PH (230-400 3PH for CE model). Use a line disconnect switch for each power supply so that the operator can turn
off the power supply quickly in an emergency. Locate the switch so it is easily accessible to the operator. The
interrupt level of the switch must be equal to or exceed the continuous rating of the fuses. Use slow-blow fuses
rated per local and national electrical codes.
Engine Drives
When using an engine drive to power the Powermax1650:
• The engine drive must be dedicated to powering the plasma cutting system.
• Engine drive operation:
1. Set the engine drive output to 3 phase AC.
2. Plug the Powermax1650 power cord into the power outlet.
3. Set the engine drive to the maximum output (see table below).
• Use unshielded consumables if you experience difficulty cutting thicker material (non-CE systems only).
