The power supply has been preset at the factory for 95 – 125 VAC or
200 – 250 VAC single phase operation, depending upon the voltage
supply available at your location. However, the laser can be switched on
site from 95-125 VAC to 200-250 VAC. In addition, the fuses must be
changed to match the voltage setting.
Figure 3-1: Voltage Switch
WARNING: Make sure that the switch is flipped to the correct
voltage. In addition, both fuses must be changed to match the
current voltage setting.
The AC power entry module located on the back of the power supply
holds two power line fuses. For 95 – 125 VAC operation two 10
amp/250V, 5 x 20 mm, time lag, high breaking capacity fuses are
installed. For 200 – 250 VAC operation two 6.3 amp/250V SPT 5 x 20
mm time lag, high breaking capacity fuses are installed. Acceptable
fuses are:
