Danger

Fatal high voltage exists between the positive and negative poles of the energy storage battery pack!

•

When maintaining the equipment, ensure that the connection between the energy storage converter and the energy storage battery pack is completely disconnected.

• Set up warning signs at the disconnection to ensure that they will not reconnect accidentally.

Danger

There is high voltage in the device. Accidental contact may cause fatal electric shock. Therefore, when carrying out live measurement, you should:

•

Do protective work (such as wearing insulated gloves, etc.).

• Must be accompanied to ensure personal safety.

Warning

After both the AC and DC sides of the energy storage system are disconnected, be sure to wait 15 minutes before opening the rear door to perform maintenance or repairs on the power distribution part.

2.2.7 live measurement
