Power Hook-Up - Challenge CHAMPION 305 Instructions And Parts Manual

6.9 Power Hook-Up

For satisfactory operation, be sure that your cutter is wired for the correct phase and voltage and has
adequate power. The correct electrical specifications for your machine are shown on the serial plate.
Check the machine serial plate before connecting the power. For future reference, transfer this
information to the front cover of this manual.
Watch Setup Voltage- Inadequate power to the cutter can be a major source of problems. Too many
machines on the same circuit will reduce the power to each machine. Inadequate voltage will cause
overheating, loss of power, and in extreme cases, failure to operate. Test line voltage when the shop
is at actual working levels. A dedicated line with a lockable disconnect is required to provide adequate
power for this machine.
power panel before working on the cutter. Lock it out to prevent accidental power up. (See
Power Lockout Procedure page 6).
Important: You must have an adequate size circuit and heavy enough wiring for this machine. The
circuit size should be a minimum of 20% greater than the amperage rating on the machine nameplate.
If a wire is run over 75 feet (23 meters), the next size wire should be used. Check local electrical codes.
