3-6. Operating Mode Description

Operating mode Description

Online mode

When the input voltage is within acceptable

range, UPS will provide pure and stable AC

power to output. The UPS will also charge the

battery at online mode.

ECO mode

Energy saving mode:

When the input voltage is within voltage

regulation range, UPS will bypass voltage to

output for energy saving. The UPS will also

charge the battery at ECO mode.

Frequency Converter mode

When input frequency is within 40 Hz to 70 Hz, the UPS can be set at a constant output frequency, 50 Hz or 60 Hz. The UPS will still charge battery under this mode.

Battery mode Bypass mode Standby mode

When the input voltage is beyond the acceptable range or power failure, the UPS will backup power from battery and alarm is sounding every 5 seconds.
When input voltage is within acceptable range but UPS is overload, UPS will enter bypass mode or bypass mode can be set by front panel. Alarm is sounding every 10 seconds.
UPS is powered off and no output supply power, but still can charge batteries.

Fault mode

When a fault has occurred, the ERROR icon and the fault code will be displayed.

Remedy Remove excess loads from UPS output.

The UPS shut down automatically because of overload at the UPS output. The UPS shut down automatically because short circuit occurs on the UPS output. A UPS internal fault has occurred. There are two possible results: 1. The load is still supplied, but directly from AC power via bypass. 2. The load is no longer supplied by power. Batteries are not fully charged
Batteries defect

Remove excess loads from UPS output and restart it.
Check output wiring and if connected devices are in short circuit status. Contact your dealer
Charge the batteries for at least 5 hours and then check capacity. If the problem still persists, consult your dealer. Contact your dealer to replace the battery.

The short circuit occurs on the charger output.
The charger does not have output and battery voltage is less than 10V/PC.

Check if battery wiring of connected external pack is in short circuit status. Contact your dealer.

5. Storage and Maintenance
Operation
The UPS system contains no user-serviceable parts. If the battery service life (3~5 years at 25°C ambient temperature) has been exceeded, the batteries must be replaced. In this case, please contact your dealer.

Storage

Be sure to deliver the spent battery to a recycling facility or ship it to your dealer in the replacement battery packing material.
21

Before storing, charge the UPS 5 hours. Store the UPS covered and upright in a cool, dry

location. During storage, recharge the battery in accordance with the following table:
