1.3.5 BATTERIES AND STORAGE
The standard batteries of the UPS are sealed, maintenance-free batteries, usually mounted in UPS cabinet
(external battery cabinet as option) and will typically be connected when the UPS is commissioned. The battery life
depends very much on the ambient temperature. A temperature range between +20°C and +25°C will achieve the
optimum battery life.
If the UPS is delivered without batteries, the manufacturer is not responsible for any damage or malfunctioning
caused to the UPS by incorrect wiring.
1.3.5.1 Storage of battery
The battery life depends very much on the ambient temperature. It is therefore important to follow the storage
instructions/recommendation of the battery manufacturer. For long-term storage make sure that the battery is fully
recharged every 6 months. Before and after storing, charge the battery.
Always store the batteries in a dry, clean, cool environment in their original packaging. If the packing container is
removed protect the batteries from dust and humidity.
SEALED BATTERIES MUST NEVER BE STORED IN A DISCHARGED OR
PARTIALLY DISCHARGED STATE.
EXTREME TEMPERATURE, UNDER- AND OVERCHARGE AND DEEP-
DISCHARGE WILL DESTROY BATTERIES!
1.3.5.2 Storage of UPS
If you plan to store the UPS prior to use, keep the UPS with its original packaging in a storage room with an
ambient temperature between (+20°C to +25°C) if the UPS contains batteries, with a temperature between (-25°C
to +70°C) without batteries and humidity of less than 95% non-condensing for both cases.
If the packing container is removed protect the UPS from dust.
THE UPS SYSTEM, THE BATTERY CABINET AND THE BATTERIES ARE HEAVY
AND MAY TIP DURING TRANSPORTATION CAUSING SERIOUS INJURY IF
UNPACKING INSTRUCTIONS ARE NOT CLOSELY FOLLOWED.
