6�2 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 same type cables together, and place them separately from cables of different types. Do
not place the cables entangled or crossed.
•
If the cable bears too much tension, the connection may be poor. Reserve a certain length of the
cable before connecting it to the inverter cable port.
•
When crimping the terminals, ensure that the conductor part of the cable is in full contact with the
terminals. Do not crimp the cable jacket with the terminal. Otherwise the inverter may not operate,
or its terminal block getting damaged due to heating and other phenomenon because of unreliable
connection after operation.
•
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.
6�3 Connecting the PE cable
•
The PE cable connected to the enclosure of the inverter cannot replace the PE cable connected
to the AC output port. Make sure that both of the two PE cables are securely connected.
•
Make sure that all the grounding points on the enclosures are equipotentially connected when
there are multiple inverters.
•
To improve the corrosion resistance of the terminal, you are recommended to apply silica gel or
paint on the ground terminal after installing the PE cable.
•
The PE cable should be prepared by the customer. Recommended specifications:
• Type: single-core outdoor copper cable
• Conductor cross-sectional area: 4-6mm
