Emergency Escape Route
To ensure personal safety in case of accidents, respect the following requirements:
Ensure that the escape route is freely accessible throughout any operation process.
Never block or lock the emergency route.
2.2.6
PV Array Protection
Voltage is present between positive and negative polarities once the PV arrays are
exposed to sunlight. The voltage is extremely high for a large scale PV plant. Electrical
shock or even death can result from inadvertent touching.
High voltages are present between the positive and negative polarities of the PV
arrays!
Ensure the inverter has been disconnected from the PV array.
Place an eye-catching warning label at the disconnection point, to avoid
inadvertent reconnection.
2.2.7
Electrical Connection
Electrical connection must be performed in accordance with the circuit diagram and the
description in this manual.
Configuration of the PV arrays and technical parameters such as grid level and
frequency must conform to technical data of the inverter.
Connect the inverter to the gird only after an approval is received from the local
power supply company and technical persons have finished the installation.
All electrical connections must comply with national/local standards.
Perform cable connections strictly according to the wiring identifications inside
the device.
2.2.8
Measuring Instrument
During electrical connection, commissioning, or the like, use related electrical measuring
instrument to ensure that the electrical parameters meet requirements.
Use quality measuring instruments with sufficient measuring range. Do not use a
conventional multimeter.
Ensure that the measuring instrument is correctly connected and used to avoid
the electrical arc and other hazards.
Take protective measures (such as wearing insulated gloves) during live line
measurement.
