PREVENTIVE MAINTENANCE
I
NTRODUCTION
Our UPS are designed and produced for long life even under the severest operating conditions. Remember however that they are
electrical power equipment items and as such are in need of periodic checks. Besides, some components have a life cycle of their
own and must therefore be checked at regular intervals and may need to be replaced, due to the conditions; in particular: the
batteries, the fans, the electrolytic and the film capacitors.
It's very important to check the requirements and the suggestions fo
r the installation environment given in the “Installation manual”.
Moreover, it is recommended to implement a preventive maintenance program, using the manufacturer authorised and trained
service personnel.
During the Maintenance all the electronics and the mechanicals parts will be controlled. This will improve the reliability, maintain the
UPS efficiency to the maximum level and to extend the lifespan.
The product safety preservation over the time is ensured with a preventive and regular maintenance program on the UPS.
Only the authorised and trained service personnel can perform any maintenance operations.
Our Technical Servicing department is at your disposal to discuss the different personalised preventive maintenance options.

ATTERIES
Thanks to an advanced battery care system our UPS preserve the batteries health both during charging and discharging phase. For
example, an algorithm to avoid deep discharge is implemented. Anyway, environmental condition and usage affect battery life. Ambient
temperature, number of blackout or outages, number of depth discharges, frequency of charge and discharge cycles are the key
factors that affect battery life. In order to avoid unexpected behavior during a mains outage, batteries should be regularly checked and
maintained by authorised service personnel.

ANS
The Fans fitted in this UPS are speed controlled. Ambient temperature and UPS output power affect the speed. In addition, dusty
environments can make matters worse. Preventive maintenance ensures that the cooling system is kept in perfect working order.
C
APACITORS
The most critical capacitors inside the UPS are the electrolytic capacitors fitted within the intermediate DC BUS and the AC film
capacitors used for input and output high frequency filtering. For our UPS we have select the best components available on the market
from well-known brands and we size them for the maximum reliability. The expected life depends however on the usage and
environmental conditions. Preventive maintenance thanks to a periodic check of the capacitors ensures the highest level of system
reliability.
