Chapter 1 Product Introduction

1.5.3 Battery Mode

Upon mains failure, rectifier overload or mains voltage out of range, the rectifier and internal charger will become

inoperative, and the battery will supply power to the load through the inverter. The inverter indicators are on together

with buzzer alarming, which notifies you that the UPS is in Battery mode.

Note

1. The battery has been fully charged before delivery. However, transportation and storage will inevitably cause some capacity

loss. Therefore, it is required to charge the battery for eight hours before putting the UPS into operation, so as to ensure the

adequate stand time for battery.

2. The battery cold start can also be used to start the UPS from the Battery (charged) mode upon mains failure. Therefore, the

battery power can be used independently for improving the system availability to some extent.

1.5.4 ECO Mode (For Single System Only)

In ECO mode, the load is powered by bypass when the bypass voltage is normal, and the load is powered by inverter

when the bypass voltage is abnormal. ECO mode is an energy-saving operation mode. For some power equipment

that insensitive to power grid quality, you can use the ECO mode for power supply through bypass to reduce the

power loss.

Note

1. In ECO mode, if the bypass failure or abnormal bypass voltage appears when the output is not overloaded, the UPS will transfer

to Normal mode. However, if the bypass failure or abnormal bypass voltage appears when the output is overloaded, the UPS will

not transfer to Normal mode, but shut down the bypass.

2. In ECO mode, the efficiency of the UPS is up to 98%.

1.5.5 Fault State

In Normal mode, the UPS will transfer to Bypass mode if the inverter failure or UPS overtemperature appears. In

Battery mode, the UPS will shut down and stop the output if the inverter failure or UPS overtemperature appears. In

Fault state, the fault indicators will turn on, the buzzer will keep beeping, and the corresponding fault information will

be displayed on LCD panel.

Note

In Fault state, if the bypass failure or abnormal bypass voltage appears when the output is not overloaded, the UPS will shut down

and be transfered to the inverter for power supply, such as radiator overheat. However, if the bypass failure or abnormal bypass

voltage appears when the output is overloaded, the UPS will not be transfered to the inverter for power supply, but shut down the

bypass.
