6.1 Security
There may be a high voltage in the conductive part of the
inverter, which may cause electric shock.Therefore, when
installing the inverter,make sure that the AC and DC sides of the
Danger
inverter are powered off.
Static electricity may damage the electronic components of the
inverter.Anti-static measures should be taken during the
replacement or installation of the inverter.
Warning
Moisture and dust penetration can damage the inverter
Make sure that the waterproof cable gland is firmly
Ø
tightened.
If the cable connector is not installed correctly, the inverter
Ø
Note
may be damaged due to the penetration of moisture and dust.

6.2 AC side wiring

Before making electrical connections, please make sure that
the DC switch of the inverter is in the "OFF" state and
disconnect the AC side MCB, otherwise the high voltage of the
Danger
inverter may cause death.
Each inverter must be installed with an AC circuit
Ø
breaker independently, and it is forbidden to share multiple
inverters.
It is forbidden to use single-core wire at the output terminal
Ø
of the inverter.
It is forbidden to use aluminum wires as output cables.
Ø
Please ensure that the output cable is well connected
Warning
Ø
before turning on the inverter.Ignoring the above warning
may damage the machine or cause other losses.In this
case, the company reserves the right not to carry out the
warranty and bear any responsibility and related expenses.
Moisture and dust penetration can damage the inverter.
Make sure the cable connector is securely tightened.
Ø
If the cable connector is not installed correctly, the inverter
Ø
may be damaged by moisture and dust. All warranty claims are
Note
invalid.
Residual current protection device (RCMU)
Because the inverter itself has a high-precision residual current detection
device,it is not recommended to install a leakage protection switch in the
system.If for some special reason,it must be installed between the inverter
output and the grid.Please install a type A leakage protection switch above
300mA.When multiple leakage protection switches are installed in the system,it
is forbidden to share the neutral line,otherwise the leakage protection function
may be triggered by mistake and cause the switch to trip.
