6 Electrical Connection

6.1 Safety Precaution

• Perform electrical connections in compliance with local laws and regulations. Including
operations, cables, and component specifications.
• Disconnect the DC switch and the AC output switch of the inverter to power off the inverter
before any electrical connections. Do not work with power on. Otherwise, an electric shock
may occur.
• Tie the cables of the same type together, and place cables of different types apart. Do not
place the cables entangled or crossed.
• If the tension is too large, the cable may be poorly connected. Reserve a certain length of the
cable before connecting it to the inverter cable port.
• Make sure that the cable conductor is in full contact with the terminal and the cable insulation
part is not crimped with the terminal when crimping the terminal. Otherwise, the inverter
may not be able to work properly, or the connection may be unreliable during working,
which may cause terminal block damage, etc.
• Wear personal protective equipment like safety shoes, safety gloves, and insulating gloves
during electrical connections.
• All electrical connections should be performed by qualified professionals.
• Cable colors in this document are for reference only. The cable specifications shall meet local
laws and regulations.
