5. CONNECTIONS
5.1. OPERATION IN HIGH EFFICIENCY MODE
The UPS has a selectable, programmable economy operating mode that can increase overall efficiency by up to 98% for energy
saving purposes. With this mode of operation, specific daily or weekly time intervals can be selected and programmed to power
the applications directly from the auxiliary mains. If there is a power cut the UPS will automatically switch onto the inverter and
continue to supply power to the load by drawing energy from the battery.
This mode does not provide perfect stability in frequency and voltage like the ON LINE mode. Thus the use of this mode should
be carefully evaluated according to the level of protection required by the application.
5.2. OPERATION IN CONVERTER MODE
In converter mode the UPS can supply a fully stabilised sinusoidal output voltage with a different frequency from the input power
line (50Hz or 60Hz is available as output frequency value).
IMPORTANT!
Only set this mode on UPS units with the mains power (MAINS) and auxiliary mains (AUX MAINS) separate, and 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!
All cables must be securely connected.
