Application steps of APC Schneider UPS power supply

APC Schneider UPS power supply will not be interrupted due to short-term power failure. It can always supply high-quality power and effectively protect precision instruments. In this regard, according to the correct steps to turn on and off the APC Schneider UPS power supply can avoid the damage to the APC Schneider UPS power supply equipment caused by the current impact at the moment of start-up, which will shorten the service life of APC Schneider UPS power supply. The following describes in detail the installation of APC Schneider UPS power supply from Startup to shutdown.

Installation steps of APC Schneider UPS power supply

1. Clear APC Schneider UPS operating environment, clean, dry, dust-free, corrosive gas, etc;

2. The specific installation path and channel should be able to bear the weight of cabinet.

3. After installing the battery of APC Schneider UPS power supply, check the total voltage of battery system, open circuit voltage of single battery, positive and negative polarity, and ensure the correct connection of positive and negative poles.

4. Check the battery management parameters in the switching power supply monitoring unit, and whether the relevant parameters are consistent with the manual.

Operation steps of APC Schneider UPS power supply

1. First determine whether the input and output lines are connected correctly.

2. When the power input switch is closed, the panel indicator light will be on. If the rectifier switch is not closed within 1 minute, the battery low-voltage alarm message will appear and the buzzer will sound.

3. When the rectifier switch is closed, the alarm information will be automatically eliminated. At this time, if the input phase sequence connection is correct, the rectifier will start within 1 minute and switch from bypass state to inverter state.

4. Close the bypass switch.

5. Close the battery switch.

6. Close the output switch.

7. After adding the load, turn off the rectifier switch, observe whether the battery can work normally, and then close the rectifier switch, APC Schneider UPS enters into normal working state.

APC Schneider UPS power off operation steps

1. Turn off the output switch after removing the load;

2. Turn off the battery switch;

3. Turn off the bypass switch;

4. Turn off the rectifier switch.

In addition, it should be noted that the maintenance bypass switch can only be closed when the APC Schneider UPS power supply is overhauled or the APC Schneider UPS power supply equipment fails. It is forbidden to close the bypass switch under the normal inverter of APC Schneider ups.

In a word, in order to ensure the service life and normal operation of APC Schneider UPS power supply equipment, the operation procedures of installation, startup and shutdown must be followed.
