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 input fuse: it may be blown. If so: replace the fuse (see 5.2) 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
