OPM_NPE_19X_600_1K5_2GB_V030 12 GE DE NetPro 19” 600-1500: User manual 3.0 (GB)

GE Digital Energy

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 (see 4, fig.1) 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 your dealer or consult

www.gedigitalenergy.com.

PROBLEM POSSIBLE CAUSE SOLUTION

UPS overload Reduce load, reset TCB

(4, fig. 1)

Thermal Circuit Breaker (TCB)

tripped

System failure Contact your dealer or consult

www. gedigitalenergy.com.

Most probably an overload See 3.3.7, reduce the loadLED 'on bypass' blinks

Overtemperature See 3.3.8

Allow the UPS to cool down

Line cord not connected Read 2.2

Connect line cord

Dead wall socket outlet, or

mains voltage out of limits

Contact qualified electrician

UPS overtemperature See 3.3.8

Allow UPS to cool down

UPS will not switch on (without

using 'battery start')

and the output has been off for

a few secs. (see also 3.2.5)

Tripped Thermal Circuit Breaker See above

UPS will not switch on after

installation, LED 'on' remains off

Batteries have been discharged

too deep during transport and/or

storage

Contact your dealer or consult

UPS overtemperature See 3.3.8

Allow UPS to cool down

Mains failure, battery

discharged

Wait until mains returns

Programmed shutdown in

progress

See 3.3.10

UPS received shut down

command from computer during

mains failure

Wait until mains returns

UPS switched off automatically

The load is < 5% of the max.

load and no mains power is

present.

(No-load shutdown function is

active, see 3.2.3)

Wait until mains returns

Battery test just after installation

or mains failure

Allow the UPS to recharge the

batteries

LED ‘replace battery’

illuminates, buzzer is silent

Battery test shows weak battery Read 6.2, replace batteries
