Residual current protection device (RCMU)
Because the inverter itself has a high-precision residual current detection device,it is not recom-
mended 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 B 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.
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 inverter are powered off.
Static electricity may damage the electronic components of the in-
verter.Anti-static measures should be taken during the replacement or
installation of the inverter.
Moisture and dust penetration can damage the inverter
> Make sure thatthe waterproof cable gland is firmly tightened.
> If the cable connector is not installed correctly, the inverter may be
damaged due to the penetration of moisture and dust. All warranty
claims are void
Before making electrical connections, please make sure that the DC
switch of the inverter is in the
11
OFF" state and disconnect the AC side
MCB, otherwise the high voltage of the inverter may cause death.
> Each inverter must be installed with an AC circuit breaker inde-
pendently, and it is forbidden to share multiple inverters.
> It is forbidden to use single-core wire at the output terminal of the
inverter.
> It is forbidden to use aluminum wires as output cables.
> Please ensure that the output cable is well connected before turn-
ing on the inverter.lgnoring the above warning may damage the ma-
chine 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.
> If the cable connector is not installed correctly, the inverter may be
damaged by moisture and dust. All warranty claims are invalid.
