Operating Mode and Instructions
An online UPS provides stable power that is not affected by an unstable main
power supply (ex. grid power). Through the online UPS, grid power can provide a
clean, noise-free power supply environment.
The online architecture offers three types of power supply methods depending
on the power environment.
Normal Mode: When grid power is normal, once RECT has been turned on at
the main power supply then the battery is charged in DC/DC mode while the
required power is supplied via INV at the same time.
Bypass Mode: In the event of UPS overload, INV failure or module
overheating, the power supply circuit switches from INV to the auxiliary (AUX)
output.
Battery Mode: When the UPS detects a failure in the main power supply then
power is provided from the battery instead. The touch screen at the front of the
module will also display current battery level to remind the user.
BRIC30S/BRIC30N offers not only the three above power supply modes but
also an Economy mode and Converter mode for special environments.

Operating Mode
4.1.1.
Normal Mode:
In Normal mode, grid power is passed through RECT then used to
charge the battery and provide power through the INV simultaneously.
Different output voltages settings can be set in VFI mode. The three
options are 380/220V, 400/230V and 415/240V. These can be
fine-tuned by
±
8V.
4.1.2.
Economy Mode:
Economy Mode (ECO Mode) effectively improves overall efficiency.
In ECO Mode grid power is routed through the AUX SCR to the load. At
the same time, grid power continues to charge the battery in DC/DC
mode through RECT following the same setup as VFI Mode. INV is also
kept ready to switch power supply modes at any time. If VFI mode is set
then power can be quickly routed from AUX to INV.
Attention: In ECO Mode the power supply frequency and voltage
will be less stable. Please check the load requirements and use
ECO Mode with care.
4.1.3.
Converter Mode:
Converter Mode allows the user to provide a power supply with
constant voltage and constant frequency based on their power
requirements. The frequency can be set to 50HZ or 60HZ. The voltage
options are 380/220V, 400/230V and 415/240V. These can be
fine-tuned by
±
8V. When Converter mode is used, in the event of grid
power failure then power is provided from the battery in Back-up mode.
In the event of the battery running low, UPS overload, INV failure or
module overheating, the entire system will shut down.
4.2.
Single Unit Operation
Check that the power supply voltage matches the UPS specifications. Make
sure the unit is properly grounded.
Before turning on grid power, make sure that the UPS module is properly
closed and in an insulated environment to avoid accidental electrocution.
