6.6.3 Mode"OFF-LINE"(ECO- or BYPASS MODE)
In the "OFF-Line Mode”, the load is supplied from the mains through the static bypass. Using the
control panel the UPS may be easily transferred to "Bypass Mode”.
When the UPS is operating in "Bypass Mode”, the efficiency of the system is higher. In the event of a
mains failure the load will automatically be transferred from mains to inverter within 5 msec (this is
valid for single and parallel systems). The battery charger remains active in the "Bypass-Mode”.
The "Bypass-Mode”, is recommended only if the loads can tolerate interruptions of 3-5 ms (transfer
time from Bypass Mode to ON-LINE Mode).
NOTE
TO HAVE THE MOST ESSENTIAL SECURITY LEVEL, WE RECOMMEND TO
RUN THE UPS ON NORMAL OPERATION MODE, MEANS ON-LINE MODE
