Fuses

The MAC 2000 Profile II comes with two:
• 20 AT (time delay) main fuses for use with AC supplies of 100 - 120 volts.
• 15 A main fuses for use with AC supplies of 200 - 250 volts.
Install the appropriate fuses in the holders near the power switch.

Power supply adjustments

The MAC 2000 Profile II (identified as such by the label on the base of the product) comes with an electronic or
magnetic ballast and an auto-sensing, auto-ranging switch-mode power supply. Manual adjustments are not necessary
unless you have the magnetic ballast version.
Magnetic ballast configuration
In magnetic ballast models the ballast must be tapped correctly
for the local AC voltage and frequency. The wrong setting can
cause overheating, damage, and poor performance. The factory
settings are printed on the serial number label.
