PREVENTIVE MAINTENANCE
I
NTRODUCTION
Every Modular UPS System appliance was designed and manufactured to be durable even under the most demanding operating
conditions. Nevertheless, please remember that they are electronic power equipment and, as such, they require regular checks.
Furthermore, some of the components have a specific life limit and must be checked regularly; it may be necessary to replace
them due to the operation conditions; in particular: batteries, fans, electrolytic capacitors and film capacitors.
It is significantly important to check the requirements and indications related to the installation environment which can be found in
the “Installation Manual”.
In addition, it is advisable to create a preventive maintenance programme which must be carried out by assistance staff specifically
trained to do so and authorised by the manufacturer.
During maintenance, all electronic and mechanic devices must be checked. This ensures the improvement of reliability, the best
maintenance of the UPS efficiency and the extension of the product’s lifetime.
The duration in time of the safety of the product is guaranteed by a preventive and regular maintenance programme of the UPS
Maintenance operations on the UPS must be performed by specifically trained and authorised personnel
only.
Our Assistance Service department is at your disposal to discuss about different custom preventive maintenance options.
B
ATTERIES
Thanks to a significant attention to batteries, our UPS preserves the health of the batteries both during charging and discharging.
For example, an algorithm has been implemented to avoid deep discharges. Nevertheless, environmental conditions and usage
affect the duration of the batteries. The environmental temperature, the number of blackouts or power supply interruptions, the
number of deep discharges and the frequency of charge/discharge cycles are all key factors which affect the lifetime of the
batteries.
In order to avoid unexpected behaviours during a blackout of the power supply line, the batteries must be regularly checked, and
the authorised assistance personnel must carry out regular maintenance operations.
F
ANS
The fans installed within this UPS are provided with a speed control system. The environmental temperature and the output power
with which the UPS operates, affect the operational speed. In addition, a dusty environment can worsen its conditions. A preventive
maintenance operation will ensure the perfect operation of the cooling system.
C
APACITORS
The most critical capacitors inside the UPS are the electrolytic capacitors that are mounted on the DC BUS and the AC film
capacitors used as input and output high-frequency filters. For our UPS, the best components available on the market have been
used, they come from known manufacturers and are designed to ensure the product’s maximum reliability. The lifetime of the
component, nevertheless, depends from the use and environmental conditions. A preventive maintenance carried out through a
regular check of the capacitors ensures a better reliability of the system.
