Although the battery had been fully charged at factory before delivery, the transport
and storage may result in loss of capacity , hence charging the battery for 8 hours is
required before installing the UPS , so as to ensure adequate battery backup time.
3.1.4 ECO Mode
ECO mode is the economic operation mode. For the load equipment which is less
critical , users can select ECO mode to power the equipment to reduce the power
consuming. When the bypass voltage is normal, the bypass powers the load and the
inverter supplies no load, bypass indicator on the Control Panel is on

, as
shown in Figure 3-4.

Note
Under ECO mode, if bypass power falls out of the bypass voltage range and there is no
overload , the UPS will switch into inverter mode; however if there is an overload and
bypass power fails or the bypass voltage is beyond the range the UPS will not go into
inverter working mode and bypass will be shut off , load will be disrupted. .
3.1.5 Failure Mode
In the event of inverter fault, internal overtemperature or other faults in Normal mode,
the UPS transfers to Bypass mode; however if this occurs in Battery mode, the UPS
shuts down.
In the event of UPS fault, the fault indicator on the LCD panel turns red, as shown in
Fig. 3-4. Meanwhile, the buzzer beeps (except battery and charger fault), and the LCD
screen displays corresponding fault information, see Appendix 1.
