Sven Pro + 1000 — решение проблем с источниками бесперебойного питания [23/25]

9. TROUBLESHOOTING

Problem

The UPS is connected to the mains with

voltage nominal, though the device

shows no voltage in the mains and enters

oﬀ-line mode.

The UPS does not start.

When power supply drops, the UPS

immediately switches oﬀ.

Solution

There is over- or undervoltage in the mains. Switch oﬀ

the PC and the UPS. Switch them on again after

voltage becomes normal.

The fuse has burned down. Replace it.

1. The battery is discharged. It is necessary to carry

out the whole cycle of battery charging.

2. The battery is out of order. It is necessary to

replace the battery.

Important! Note that battery operation time is limited to 3-20 minutes, if mains power supply

is cut off. During this time it is necessary to save all open documents and switch off the PC,

then the UPS should also be switched off.

8. BATTERY MAINTENANCE

Pro+ UPS series contains one or two maintenance-free sealed lead-acid batteries. High humidity,

too high or low temperature, frequent battery discharge reduce its durability. If battery has not

been operated for a long period of time, it also has negative impact on its durability. Therefore, it is

recommended to carry out the whole cycle of battery charging/discharging at least once per three

months.

Storage conditions

• The UPS should be stored closed in vertical position in a dry and cool place with fully charged

storage battery.

• Before placing the UPS in storage, charge it for 10 hours.

Warning! Do not operate the UPS in environment with operating temperature not corres-

ponding to value given in Technical Speciﬁcations.

If none of the above methods can solve the problem, please seek professional advice at your

nearest service center. Never attempt to repair the product yourself.
