8 - Troubleshooting
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 fig. 3.3.3 a/b) 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.
