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.
