3.3.5 Power-On Measurement
After the energy storage battery is installed, there is a high voltage present, and accidental contact
with the positive and negative terminals may result in electric shock injuries. Therefore, when
conducting power-on measurements, attention should be paid to the following:
1. Take necessary insulation protection measures (such as wearing insulated gloves).
2. Accompanying personnel must be present to ensure personal safety.
3.3.6 Measuring Instruments
When performing electrical connections and trial operations on the energy storage backup battery,
and to ensure that electrical parameters meet requirements, relevant electrical measuring
equipment such as multimeters, power meters, etc., should be used. Note the following:
1. Use measuring equipment with a suitable range that conforms to on-site working conditions.
2. Ensure the correct and standardized electrical connections of the instruments to avoid dangers
such as electric arcs.
3.3.7 Maintenance and Inspection
When both the energy storage battery and the inverter are turned off, and electrical connections
are confirmed to be disconnected, maintenance or inspection operations can be carried out on
the energy storage battery cabinet. Pay attention to the following:
1. Ensure that the energy storage battery will not be accidentally re-energized.
2. Use a multimeter to ensure that the energy storage battery is completely de-energized.
3. For parts near potentially live components during operations, use insulating materials for
insulation covering or grounding.
4. It is strictly prohibited to perform maintenance or inspection operations on live equipment!
When performing maintenance or inspection on equipment, it must be ensured that at least
two personnel are present at the site. Maintenance operations can only be carried out after the
