5. CONFIGURATION
Any configuration modification must be applied with UPS connected to AC line but in OFF or STAND-BY mode.
This UPS can be configured to work under some different modes. Some important functions can also be configured in CONFIGURATION
MODE:
a) Normal Mode: Also known as AC MODE. Under this mode UPS works as ONLINE UPS. UPS outlets are supplied by AC power
generated by UPS inverter circuit offering a clean power to your devices.
b) ECO Mode: Under this mode UPS works as OFF-LINE UPS. UPS outlets are supplied by AC input source. UPS supervises input
source to switch to ONLINE mode only when input source is out of range This is not a recommendable mode for those critical
applications that require ONLINE UPS.
Default mode set as factory is NORMAL MODE (Online UPS).
c) Output Voltage: It can be configured to any of 4 available values:
In 120Vac Models: 110Vac, 115Vac, 120Vac, 127Vac,
In 220Vac Models: 208Vac, 220Vac, 230Vac ó 240Vac
d) Output Frequency: It can be selected to 50Hz or 60Hz. Default configuration allows auto-selection to match with frequency of
input AC source. NOTE: When conversion frequency mode is activated UPS power capacity could be reduced
e) Programmable Outputs: There are 2 groups of outlets:
 Standard Outlets: They work as expected in any UPS. This kind of outlets under battery keep powered until batteries reach very
low level or up to UPS receives power off command from software.
 Programmable Outlets: If programmable outlets function is configured, programmable outlets can be powered off by internal
timer before UPS detects very low battery level. Most common application for programmable outlets is for connecting non critical
devices to them so that backup time can be longer for those critical devices connected in standard outlets.
6. OPERATION
This is UPS is ONLINE DOUBLE CONVERSION type and it has been designed to offer the most clear power without switching transitions or
dead times. In that way your hardware but also your valuable data will be safe when your PC related equipment is connected to OPTIMA
series UPS.
Power output is sine-wave type same as supplied by AC main source.
Depending of AC input source, this UPS can work under one of two following modes:
Stand-By Mode: UPS goes to Stand-By mode when it is just connected to AC input source. BYPASS mode must not be previously
activated. If BYPASS is activated, UPS will go to BYPASS mode just after UPS is connected to input source.
Normal AC Mode (Online) : It is the default mode when AC input source is OK and ON button is selected. If ON button is not selected, UPS
will remain in stand-by mode or bypass (if bypass has been configured as ENABLE)
Under normal online mode, power output is generated by UPS inverter. Inverter takes power from AC/DC converter feed by AC input
source. AC input source is only used under this mode to recharging batteries when necessary.
Battery Mode: Also known as Inverter Mode. It is the mode when AC input source is out of range or black-out is detected by the UPS.
Under this mode power output is generated by UPS inverter that takes power from batteries.
There is no dead time (transition time is ZERO ms) related to switching from normal mode to battery mode since load is always powered
from inverter. This is main characteristic of an ONLINE UPS.
BYPASS Mode: Bypass is a working state where UPS supply outlets directly from input AC source. In this mode Inverter does not supply
outlets from inverter.
Bypass mode can be forced by user from Online mode by selecting ON & SELECT buttons at same time during 5 minutes. It can be also
activated by configuring BYPASS as enable in configuration menu and connecting UPS to AC source without activating ON button.
Bypass mode can be also forced in automatic way by UPS in case it detects external overload or internal failure.
ECO Mode: This UPS also offer a third operation mode name ECO MODE. Under this mode (selectable by LCD configuration menu) UPS
works as OFF-LINE UPS. Load is powered from AC input and UPS only switch to battery mode when input is out of range or in black-out
status. Transition time from ECO mode to Battery mode is not zero. Typically is about 4ms that is why ECO Mode is not recommended for
critical applications.
