Factory set to 380 V - 400 V or 415 V can be selected by service engineer at site.
2
Factory set to 50 Hz - 60 Hz 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.
