What should be done when APC Schneider UPS power supply fails to start?

APC Schneider UPS power supply in the use of the process, sometimes encounter some unpredictable faults, many common problems can be checked and dealt with by themselves, learning UPS power maintenance knowledge has become particularly important. The following describes the situation that APC Schneider UPS power supply fails to start:

Case 1: the newly installed APC Schneider UPS UPS fails to start normally.

The reason why the user can connect the two UPS power supplies first is that the battery plug of Schneider can not be connected to the back of the ups. If not, open the front panel to check if the battery is connected.

The second case: the ups battery has been used for about 2 years, leading to APC Schneider UPS power failure to start.

This situation is generally due to the battery after two years of use, generally more or less battery capacity decline or battery inertia, if the battery can not play the role of delay, users need to consider the replacement of a new battery, to avoid the problem of battery inertia, can use battery automation management software 。

The third case: the voltage of single battery is normal, but the UPS power supply can not be started.

At this time, although the single battery voltage is normal, it may be caused by some other reasons that the UPS power supply can not start.

1. It is likely that there are problems in the connection between batteries or between batteries and UPS power supply, such as the connection point is not firm or the connection point is oxidized. In this case, it is necessary to remove the oxide and then re connect.

2. It may be that the fuse of UPS power supply and battery connection is broken. If the fuse is broken, replace the fuse.

3. The connection between UPS power supply and battery is very long and thin, or there is a connection point in the middle, so there is a great voltage drop, resulting in the UPS power supply can not be started.

The fourth case: UPS inverter can not start normally after a period of time.
