N O T E:
1. Factory set to 38 0 V, 400V or 415V can be selected b y service eng ineer at site.
2. Factory set to 50H z or 60 H z can be selected by service engineer at site. Note that th e system
freq u ency can be changed only w hen the U PS is on bypass. It is strictly p rohibited to change the
system freq uency when the U PS is on inverter.
