● In order to facilitate cooling and maintenance, sufficient space must be left around the inverter.
● In order to achieve a good cooling effect, the inverter must be installed vertically and ensure smooth air circulation.
● If the installation is not secure, place a flat plate under the base of the inverter before installing. If installed on a
loose surface, the stress may cause damage to the main circuit parts, thus damaging the inverter;
● The installation wall should use non-combustible materials such as iron plates.
● When multiple inverters are installed in the same cabinet, pay attention to the spacing when installing them up and
down, and add a baffle plate in the middle.
● Be sure to correctly connect the inverter main circuit and control signal wires.
● Be sure to set the inverter parameters correctly.
Note: Power supply: Please pay attention to whether the voltage levels are consistent to avoid damage to the inverter.
The environment of the installation site will affect the service life of the inverter.
