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. 3.3.5.a/b) and be sure that the
UPS is not overloaded.
The following chart is a simple troubleshooting checklist. If the suggested solution does not succeed, or if
the information is insufficient to solve the problem, please contact your dealer or consult
