1.3.3 Storage
If the equipment is not installed immediately, it must be stored in a room protected against excessive humidity
and heat sources (see Table.9-2).
The battery needs to be stored in dry and cool place with good ventilation.
The most suitable storage temperature is from 20 ºC to 25ºC.
Preventing battery slow discharge
Should the UPS remains unpowered for a prolonged period of time while the battery are connected, the
batteries may slowly discharge and being so permanently damaged .In such cases it is therefore
recommended to leave the battery circuit breaker(s) open. During storage in any case, periodically charge
the battery according to the battery user manuals.
1.4 Positioning
When the equipment has been positioned, ensure the UPS will remain stationary and stable.
To guarantee optimize working lifetime, the place chosen must guarantee:
Space for easy operation on the UPS
Enough air to dispel heat produced by UPS
Protection against atmospheric agents
Protection against excessive humidity and heat sources
Protection against dust
With the current fire prevention requirements
The operating environment temperature is within +20°C to +25°C. The batteries are at maximum
efficiency in this temperature range (for information about the battery storage and transportation as well
as the environment, refer to Table.9-2 )
This equipment is of steel frame structure wrapped by removable panels. The cover and the lateral
panels are fixed by screws.
After opening the UPS rack door, the auxiliary connections for communitation ports and dry-contact and
the maintenance bypass can be accessed.
The UPS provides air inlet port in the front and the air exhaust port in the rear part. It is forbidden to
install the UPS directly to the rear wall. Leave at least 50cm of free space in the rear. See picture
