Precautions for installing Schneider modular UPS power supply

Modular UPS power supply can install all modules in the standard cabinet, which saves the floor space and is helpful for installation, use and maintenance. Today, the UPS power supply manufacturer will give a detailed introduction:

1. The input zero line and output zero line of Schneider modular ups are isolated or the interference is eliminated by choke ring. Therefore, when doing the power distribution of Schneider UPS, the output zero line of Schneider UPS cannot be connected to the zero line busbar of input distribution.

2. When the Schneider UPS power supply is equipped with the I / O circuit breaker, the rated voltage of the circuit breaker shall conform to the rated I / O voltage of Schneider ups. If the rated voltage of the single input single output Schneider UPS single pole is AC220V or 250V, the three input three output UPS can select the circuit breaker with the rated voltage of AC380V or 415V.

3. The fluctuation value of the input mains supplied by the user to the ups often needs to be less than the nominal allowable mains dynamic value of the UPS power supply. Zero ground voltage is often required to be less than 1.5V without load and 2V with full load.

4. The connection between Schneider UPS power supply and external long-time delay battery shall not be too long, otherwise the loss voltage drop will be too large when the battery is connected. Users pay great attention to the ambient temperature and humidity when the UPS power supply host works. The battery and the host are placed at the same time to make the battery have a good working environment.

5. Pan geographic Schneider UPS power room monitoring system consists of front-end equipment, client / server app, and PC large screen. The operation status and relevant data of the nursing system can be visualized on the large screen of the mobile phone. In case of any abnormality, both parties can receive the alarm information synchronously.

6. Filter capacitors are added between zero and fire wires to eliminate common mode interference. Both zero and fire wires have current to ground, which will cause unequal current on zero and fire wires and trip the circuit breaker with leakage. The circuit breaker with leakage protection is not allowed for the former stage and load of Schneider UPS in the circuit to avoid the accidental power failure caused by Schneider ups and load.

7. Schneider modular UPS power supply and its load are separately set with distribution board, which is helpful for centralized and reliable control of Schneider ups and protection load.

8. Schneider UPS input circuit breaker controls UPS input power on and off separately, so the lower port of UPS input circuit breaker does not need to be connected with other electrical equipment to avoid normal UPS input power on and off.

Schneider modular UPS enables continuous growth of capacity with the development of business. At the same time of meeting the later business expansion needs, it also reduces the user's initial purchase expenses.
