Note
With the function of Battery cold start, the UPS may start without utility. See more detail in
section 5.1.2.
2.3.3 Bypass Mode
If the inverter overload capacity is exceeded under Normal mode, or if the inverter
becomes unavailable for any reason, the static transfer switch will perform a transfer
of the load from the inverter to the bypass source, with no interruption in power to the
critical AC load. Should the inverter be asynchronous with the bypass, the static
switch will perform a transfer of the load from the inverter to the bypass with power
interruption to the load. This is to avoid large cross currents due to the paralleling of
unsynchronized AC sources. This interruption is programmable but typically set to be
less than 3/4 of an electrical cycle, e.g., less than 15ms (50Hz) or less than 12.5ms
(60Hz). The action of transfer/re-transfer can also be done by the command through
monitor.
Fig. 2-6 Bypass mode operation diagram
2.3.4 Maintenance Mode (Manual Bypass)
A manual bypass switch is available to ensure continuity of supply to the critical load
when the UPS becomes unavailable e.g. during a maintenance procedure. (See
Fig.2-7).

Danger
During Maintenance mode, dangerous voltages are present on the terminal of input, output and
neutral, even with all the modules and the LCD turned off.
2.3.5 ECO Mode
To improve system efficiency, UPS rack system works in Bypass mode at normal
time, and inverter is standby. When the utility fails, the UPS transfers to Battery Mode
and the inverter powers the loads.
Fig.2-8 ECO Mode operation diagram
Note
There is a short interruption time (less than 10ms) when transfer from ECO mode to battery mode,
it must be sure that the interruption has no effect on loads.

Product Introduction
2.3.6 Auto-restart Mode
The battery may become exhausted following an extended AC mains failure. The
inverter shuts down when the battery reaches the End of Discharge Voltage (EOD).
The UPS may be programmed to “System Auto Start Mode after EOD”. The system
starts after a delay time when the AC mains recovers. The mode and the delay time
are programmed by the commissioning engineer.
2.3.7 Frequency Converter Mode
