Why does my EATON ELLIPSE PRO 1600 IEC UPS turn off by itself?

Question

Accepted Answer

Your EATON ELLIPSE PRO 1600 IEC UPS turns off automatically for several reasons, usually related to its overload protection, battery depletion, or an internal fault. Each shutdown is accompanied by specific alert signals visible on the LCD screen and audible via the sound alarm, which allow you to identify the exact cause.

Overload on the protected outlets: If the total power of the devices connected to the protected outlets (19) exceeds the nominal capacity of 1600 VA / 960 W, the output circuit breaker (20) automatically trips. You will see button 6 flashing green and hear a sound alarm every 3 seconds. Unplug the device causing the overload and reset the circuit breaker by pressing its button located at the back of the UPS. Ensure that the cumulative current does not exceed the amperage values indicated on each outlet.

Battery autonomy depleted: During a power outage, if its duration exceeds the available autonomy of your lead-acid battery, the UPS automatically turns off and then restarts when the power returns. After a complete discharge, it takes several hours for the battery to regain its nominal autonomy. On first use, wait at least 8 hours of charging before relying on full autonomy. To optimize performance, keep the UPS plugged into the electrical network continuously, which maintains the battery in good condition.

Battery lifespan: Your ELLIPSE PRO 1600 IEC contains a lead-acid battery with a typical lifespan of 4 years, varying according to the operating temperature (0 to 35 °C) and the number of discharge cycles. An aged battery gradually loses its capacity and may lead to premature shutdown. If the UPS turns off quickly during a power outage after several years of use, have the battery replaced through EATON's customer service.

Internal fault or overheating: An internal fault is indicated by the fault symbol (12) that appears on the LCD screen accompanied by a continuous sound alarm. In this case, the protected outlets are no longer powered. Ensure that the UPS operates in a correct ambient temperature (between 0 and 35 °C) and that its vents are not obstructed. An excessively hot environment causes shutdown for protection. Make sure the UPS has free space around it for proper air circulation.

EcoControl function activated: If you have configured the EcoControl function via the provided configuration software, the EcoControl outlets automatically turn off when the main application connected to the Master outlet is turned off. Check in the software settings if this function is activated (it is disabled by default).

If the problem persists despite these checks, contact EATON customer service with the model number ELLIPSE PRO 1600 IEC for a thorough diagnosis and possible repair.
