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
