Caution
For changing the input/output voltage or fuses the isolation transformer should not be connected. The wrong
fuses and position of the input/output voltage selector may cause major damage on connected peripherals.
1. Before using the Isolation Transformer you must check the input/output voltage settings to meet the
ratings of the line power available in your location or country.
2.
For changing the input/output voltage, remove the label by means of a small socket wrench.
3. Switch both voltage selectors (input as well as output voltage) to 115V or 230V. Consider that changing
the input/output voltage also requires to change the fuses!
Figure 8-35 change input/output voltage
4. For changing the fuses, open the fuse protection at the power inlet block with a small screwdriver,
remove the fuse holder and exchange fuses.
Figure 8-36 exchange
fuses
115V (100-130V) -> 4AT
