What should I do if the apcups power supply fails to start?

In the process of using apcups power supply, sometimes it will encounter some unpredictable faults, many common problems can be solved by yourself, so it is very important to learn the UPS power supply maintenance knowledge. In the process of using apcups power supply, sometimes it will encounter some unpredictable faults, many common problems can be solved by yourself, so it is very important to learn the UPS power supply maintenance knowledge. The following is a detailed introduction of UPS power failure:

Case 1: the newly installed UPS cannot start normally.

This may be caused by two reasons. The user can check whether the battery connection plug on the back panel of UPS power supply is connected first. If not, open the front panel to check if the battery is connected.

Case 2: the UPS power battery has been used for about 2 years, and the UPS power cannot be started.

For most users, this situation is generally due to more or less battery capacity decline or battery inertia after two years of use. If the battery cannot play a role of delay, users need to consider replacing the new battery to avoid the problem of battery inertia. We can use battery automation tube Manage software.

Case 3: the voltage of single battery is normal, but the ups cannot be started.

At this time, although the voltage of a single battery is normal, it may be caused by some other reasons that the ups cannot be started.

1. It is likely that there is a problem in the connection between the battery and the battery or between the battery and the UPS power supply. For example, the connection point is not firm or there is oxidation at the connection point. In this case, it is necessary to remove the oxide and reconnect.

2. Maybe the fuse between UPS power supply and battery is broken. If the fuse is broken, replace it with another fuse.

3. The connection between the UPS power supply and the battery is very long, thin or there is a connection point in the middle, so a large voltage drop is generated, which causes the UPS power supply to fail to start.
