Perform electrical connections in compliance with local laws and regulations. Including
operations, cables, and component specifications.
Disconnect the DC switches and the AC output switches to power off the equipment
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.
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 device 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.
For parallel systems, follow the safety precautions in the user manuals of related
products in the system.
N and PE wiring ON-GRID and BACK-UP of the inverter are different based on the
regulation requirements of different regions. Refer to the specific requirements of local
regulations.
There are built-in relays inside of the inverter’s ON-GRID and BACK-UP AC ports. When
the inverter is in the off-grid mode, the built-in ON-GRID relay is open; while when the
inverter is in grid-tied mode, it is closed.
