MASTERYS BC+ 60-80 kVA - Ref.: IOMMASBCXX0F-EN 00
10.3 CONVERTER MODE
In converter mode the UPS can supply a fully stabilised sinusoidal output voltage with a different frequency from the
input power line (50 Hz or 60 Hz is available as output frequency value).
NOTE: only set this mode on UPS units with the auxiliary mains (AUX MAINS) disconnected! Do
not set this mode on UPS units with common mains lines as it could damage the load!
10.4 OPERATION WITH MAINTENANCE BYPASS
If the internal maintenance bypass is activated using the appropriate procedure, the load is powered directly from the
maintenance bypass, while the UPS is separated from the power supply and can be switched off.
This operating mode can be selected for maintenance to be carried out on the system, so that the necessary actions
can be performed by service personnel without having to disconnect the power supply to the load.
10.5 OPERATION WITH MOTOR GENERATOR (GENSET)
The UPS can be operated in conjunction with a generator (GENSET) over the ADC+SL card (refer to 'Standard
features and option' chapter). With a generator, the frequency and voltage ranges of the auxiliary mains can be
increased to accept the instability of the GENSET and at the same time to avoid operation from the battery or risks of
out-of-synchronisation switching on to the bypass.
