1. Factory set to 380V. 400V or 415V can be selected by service engineer at site.
2. Factory set to 50Hz. 60Hz can be selected by service engineer at site. Note that the system frequency can be
changed only when the UPS is on bypass. It is strictly prohibited to change the system frequency when the UPS
is on inverter.

3. External bypass fuses are mandatory for the declared short-circuit current protection value. Maximum
allowable value of projected short-circuit current at the input terminals of the fuses. If no external bypass fuses
are fitted, the short-circuit current value must be assumed to be 20kA
