ENGLISH 8. Troubleshooting UPS overtemperature LED is On. 1 beep every 3 seconds. The UPS does not start. Input bad wiring / Output bad wiring The UPS internal temperature is too high or a fan has failed. At the warning level, the UPS generates the alarm but remains in the current operating state. If the temperature rises another 10°C, the UPS transfers to Bypass mode or shuts down if Bypass is unusable. The input source is not connected correctly. The Remote Power Off (RPO) switch is active or the RPO connector is missing. Input/Output cables are not connected to the correct terminal blocks. If the UPS transferred to Bypass mode, the UPS will return to normal operation when the temperature drops 5°C below the warning level. If the condition persists, shut down the UPS. Clear vents and remove any heat sources. Allow the UPS to cool. Ensure the airflow around the UPS is not restricted. Restart the UPS. If the condition continues to persist, contact your service representative. Check the input connections. If the UPS Status menu displays the "Remote Power Off" notice, inactivate the RPO input. Connect correctly the Input/Output cables. Led is On. Beep continuous. MBP disconnected The HotSwap MBP is no more connected to the UPS. If the HotSwap MBP is connected to the UPS, check that the detection connector is correctly plugged. 9PX3K3U_EN Page 39
