3.3 STORAGE

3.3.1 Storage of the UPS

The UPS is carefully packed for transport and storage so that it is in perfect condition when installed.
Never leave a UPS outside the building and don’t store other packages on the top of the UPS.

It is advisable to store the UPS in its original package in a dry, dust-free room, away from chemical
substances, and with a temperature range not exceeding -13°F (-25°C) to 131°F (55°C).
In case the battery is included please refer to Section 3.3.2.

Some important functions of the UPS, such as the customized functions, are defined by parameters
stored in a RAM memory.
A small backup battery located on the Control Unit board supplies the RAM.
If the storage time of the UPS exceeds 1 year, these functions should be verified by an authorized
Service Center before putting the UPS into operation.

3.3.2 Storage of battery

When the delivery includes a maintenance free battery, keep in mind that they are subject to self­discharge and therefore you must recharge the battery.

The storage time without battery recharge depends on the temperature of the storage site.

The optimal temperature for Battery storage is 68°F (20°C) to 77°F (25°C) and shall never exceed the
range -4°F (-20°C) to 104°F (40°C).

Recharge stored maintenance free battery every:

6 months when the storage temperature is 68°F (20°C)

3 months when the storage temperature is 86°F (30°C)

2 months when the storage temperature is 95°F (35°C)

WARNING !

A QUALIFIED ELECTRICAL CONTRACTOR must carry out the installation and cabling
of the UPS.

If optional cabinets and accessories are included with the UPS, please refer to those
accompanying manuals for installation and operating instructions.

It is important to have a clean, dust-free environment provided with proper ventilation and air­conditioning to keep the ambient temperature within the specified operating range.

The recommended air inlet temperature is from 68°F (20°C) to 77°F (25°C) (max. 104°F / 40°C).
Refer to Section 3.5.

Check for sufficient floor load capacity before installing the UPS and the Battery.
Refer to Section 3.1.1.

For Battery installation follow the local codes and the recommendation of the battery supplier.

NOTE !

Temperature is very important for valve-regulated batteries (maintenance free).
Operation at temperatures higher than 77°F (25°C) will reduce battery life.

The SG Series 225 & 300 UPS can radiate radio frequency energy.
Although some RFI filtering is inherent to the UPS there is no guarantee that the UPS will not influence
sensitive devices such as cameras and monitors that are positioned close by.
If interference is expected, the UPS should be moved away from the sensitive equipment.

A single-phase power outlet (120 Vac) should be provided near the UPS for connection of power tools,
test equipment or connectivity devices. This outlet must be grounded.
