Whenever a malfunction occurs, first check external factors (e.g. connections, temperature, 

humidity or load) to determine whether the problem is caused by the unit itself or by its 

environment. Subsequently check the thermal circuit breaker: it may be tripped. If so: reset it 

and be sure that the UPS is not overloaded. 

The following chart is a simple troubleshooting checklist only. If the suggested solution does 

not succeed, or if the information is insufficient to solve the problem, please contact

PROBLEM 

POSSIBLE CAUSE 

SOLUTION 

 

 

 

UPS overload 

Reduce load, reset breaker 

Input Circuit Breaker tripped 

System failure 

Contact your dealer or consult 

www.gedigitalenergy.com 

UPS will not switch on 

Line cord not connected 

Connect line cord 

 

Dead wall socket outlet, or 

mains voltage out of limits 

Contact qualified electrician 

 

Tripped input circuit breaker 

Check whether UPS is not 

overloaded, reset breaker 

 

Battery voltage too low 

Allow UPS to recharge the battery 

 Batteries 

not 

connected 

Contact your dealer or consult 

www.gedigitalenergy.com 

UPS has no output 

UPS over-temperature 

Allow UPS to cool down 

 

Utility failure, battery depleted  Wait until utility power returns 

 

Input breaker tripped 

See above 

LED ‘Fault’ lights up, buzzer 

sounds continuously 

Internal UPS failure 

Contact your dealer or consult 

www.gedigitalenergy.com 

LED ‘Fault’ flashes 

Wiring fault (L-N reversed) 

Have site wiring checked by 

qualified electrician 

LED ‘Battery low’ lights up, 

buzzer beeps 2x/sec. 

Battery is close to being 

exhausted during utility failure 

The UPS output will be lost soon. 

Shut down the load in an orderly 

manner 

LED ‘Replace battery’ lights up, 

buzzer sounds continuously 

Battery test just after a utility 

failure (‘false alarm’) 

Allow the UPS to recharge the 

battery for approx. 8 hours, then 

repeat the battery test 

 

Battery is close to being worn 

out 

Allow the UPS to recharge the 

battery for approx. 8 hours, then 

perform battery test. If the alarm 

persists, consider battery 

replacement 

LED ‘Overload’ lights up, 

buzzer sounds continuously 

UPS is overloaded 

Reduce load, e.g. by unplugging 

non-critical load 

Buzzer sounds continuously: 

over-temperature 

Ambient temp. too high, or 

ventilation blocked 

Reduce ambient temperature, 

enhance ventilation 

 

Fan failure 

Have the fan replaced 

UPS cannot be linked to
