Ensure the stability of UPS by fixing the feet to the floor.
The UPS should be mounted on a concrete surface and non-combustible surface.
In order to profit from optimal ventilation, the side panels must remain in place for UPS with
internal battery.
Optimal battery life time is reached when battery ambient temperature is kept between
15°C and 25°C. Operating battery at 30°C ambient temperature compared to 20°C will
divide by factor 2 battery life time. Room thermal management as specified above is
then necessary to avoid battery life time reduction. The Battery warranty does not apply
if the temperature in the room exceeds 25°C.

Storage
Please store the UPS in an environment where the temperature is between -25 ° C + 55 ° C, no receipt of
direct sunlight, far from the heating, in a dry place.
Environmental humidity must be between 20-95% (non-condensing).
Recommended storage temperature, humidity and altitude values are listed on the Appendix-1 Technical
Specifications section.
If the batteries will be stored for longer than 6 months, they shall be charged periodically. Charge period
depends on the storage temperature, as shown below:
• Every 9 months if the temperature is below 20°C,
• Every 6 months if the temperature is between 20°C and 30°C,
• Every 3 months if the temperature is between 30°C and 40°C,
• Every 2 months if the temperature is over 40°C
For long storage duration; please follow up the instructions of installation described in Section 5, start-up
UPS described in Section 6 and charge the batteries at least 10 hours.

Electrical Requisites
The installation must comply with national installation regulations.
The electrical distribution panels for common mains supply voltage and auxiliary mains supply voltage
inputs must have a protection and disconnection system. Disconnection devices used in these panels
shall disconnect all line conductors simultaneously. The following table shows the recommended size
of common mains supply voltage and auxiliary mains supply voltage input protection devices (thermal,
magnetic and differential) and the cable cross-sections for the linear loads.
.
When dual inputs is used:
• Separate Neutral conductor is necessary to be supplied for each input: Common
Mains Input and Auxiliary Mains Input
• The two inputs should be supplied by the same MV/LV transformer source. If this is
not the case, an insulation transformer should be added in the auxiliary mains line
upstream the UPS.
• Separate protection is necessary for each input line.
