1. Make sure that the clearance around the plasma power supply is adequate.

For adequate ventilation, Hypertherm recommends a minimum separation
distance of 1 meter (3.3 feet) between the plasma power supply and any
other objects or equipment.
2. Make sure that the ambient temperature where the plasma power supply is located is within the
acceptable temperature range for cutting system operation (See
Table 1
on page 27.)

If the temperature where your plasma power supply is located is above the
temperature limit, you can experience reduced performance and
over-temp diagnostic codes.
3. While all of the fans continue to operate, allow the cutting system to cool.
4. Without removing the external side panel on the plasma power supply, look through the
ventilation trusses on the plasma power supply to examine both magnetic fans inside.

Look through the ventilation trusses on the front of the plasma power
supply to locate the 2 magnetics (254 mm / 10 inch) fans inside. It is
not
necessary to remove the external panels to view the magnetics fans.
Magnetic fans are near the front and bottom.
WARNING
ELECTRIC SHOCK CAN KILL
Disconnect electrical power before doing any maintenance.
All work requiring removal of the plasma power supply panels must be
done by a qualified technician.
See the Safety and Compliance Manual (80669C) for more safety
precautions.
