4.3. 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.
4.4. 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.
In order to profit from optimal ventilation, the side panels must remain in place for UPS with internal
battery.
The UPS should be mounted on a concrete surface and non-combustible surface.
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.
