Possible cause: Batteries not fully charged.

Solution: Charge batteries for at least 8 hours and then check their charge level. If problem persists, contact distributor or seller or, failing that, our TSS.

Possible cause: Batteries defective.

Solution: Contact distributor or seller or, failing that, our TSS for battery replacement.

Possible cause: No voltage at input.

Solution: Check for mains voltage.

Possible cause: Input power cables badly connected.

Solution: Check input power cables firmly connected to mains and UPS.

Possible cause: Input cable connected to IEC output connector on UPS.

Solution: Correctly connect input cable to respective IEC connector.

Possible cause: UPS turns off automatically due to short circuit at output.

Solution: Check output wiring and that connected loads not short-circuited.

Possible cause: Voltage of batteries too high or charger faulty.

Solution: Contact distributor or seller or, failing that, our TSS.

Possible cause: Voltage of batteries too low or charger faulty.

Solution: Contact distributor or seller or, failing that, our TSS.

Possible cause: The UPS turns off automatically due to overload at output.

Solution: Disconnect the excess loads from the output sockets and restart it.

Possible cause: Charger does not provide output and battery voltage less than 10 V per element.

Solution: Disconnect excess load from output sockets and restart device.

Possible cause: EPO (emergency power off) function activated.

Solution: Close EPO signal circuit (fit connector with jumper) to deactivate it.

Possible cause: Internal or external batteries badly connected.

Solution: Check all batteries properly connected.

Possible cause: UPS overloaded.

Solution: Disconnect excess load from UPS output sockets.

Possible cause: The UPS is overloaded and connected loads are powered directly from the mains through the Bypass.

Solution: Disconnect excess load from UPS output sockets.

Possible cause: After repetitive overloads, the UPS is locked in Bypass mode and connected loads are powered directly from the mains through the Bypass.

Solution: Disconnect the excess loads from the output sockets, shut down the device and restart it.

Possible cause: Neutral to earth fault detection. Phase and neutral input cables inverted.

Solution: Disconnect input plug from AC power socket and invert connection of phase and supply neutral (rotate plug 180º).

Possible cause: Internal fault in UPS.

Solution: Contact distributor or seller or, failing that, our TSS.
