6�1 Safety Precautions
•
Disconnect the DC switch and the AC output switch of the inverter to power off the equipment
before any electrical connections. Do not work with power on. Otherwise, an electric shock
may occur.
•
Perform electrical connections in compliance with local laws and regulations. Including
operations, cables, and component specifications.
•
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.
•
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 should meet
local laws and regulations.
6�2 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. Both of the two PE cables must be securely connected.
•
Make sure that all the grounding points on the enclosures are equipotential connected
when there are multiple inverters.
•
To improve the corrosion resistance of the terminal, it is recommended to apply silica gel or
paint on the ground terminal after installing the PE cable.
•
The PE cable should be prepared by customers. Recommended specifications:
•
Type: single-core outdoor copper cable
•
Conductor cross-sectional area: 4mm
