it is necessary to charge the storage battery for at least 12 hours. For this purpose the UPS should

be switched on without load.

• If the storage battery has fully run down or the UPS has not been operated for three months, it is

also necessary to charge the storage battery for at least 12 hours. Otherwise, its durability will be

considerably reduced.

• We pay your attention that batteries composing UPS are consumables and are not subject to

warranty replacement.

• The UPS is designed solely for operation with PCs equipped with switching power supply units*.

It is strongly forbidden to connect inductive or capacitive load, as well as fully resistive load. Such

loads include any devices with transformer power unit, electric engines, ﬂuorescent lamps, laser

printers, any heating appliances, etc.

• During operation, the case of the device can be heated up to 50°C, which is absolutely normal.
