INSTALLATION
2-1 Installation environment
•
Locations free of water droplets, vapors, dust and oily dust.
•
Non-corrosive, flammable gas and liquid.
•
No floating dust metal particles.
•
The environment temperature is -10°C
~
50°C. If the environment
temperature exceeds 40°C, please place it in a well ventilated place
and delete the inverter
•
Strong and vibration-free place.
•
Locations without electromagnetic noise interference.
2-2 Installation method and space
•
The inverter should be installed on a structure that does not burn, such
as metal, otherwise a fire accident may occur.
•
The inverter should be installed vertically and securely with screws. Do
not flip, tilt or install horizontally. When the inverter runs, heat is
generated. To ensure the passage of the cooling air, a certain space is
left during installation (as shown in the figure).
•
When installing the inverter in the control cabinet, consider ventilation
and heat dissipation to ensure that the ambient temperature of the
inverter does not exceed the specified value. Do not install the inverter
in a closed box with poor ventilation.
•
When installing multiple inverters in the same control cabinet, it is
recommended to install them side by side in order to reduce the
thermal impact between each other. If it is necessary to install up and
down, a partition plate must be provided to reduce the influence of heat
generated in the lower part on the upper part (as shown in the figure).
•
Do not allow foreign matter such as various fibers, paper sheets, chips
(chips) or metal fragments to enter the inverter.

WIRING
In order to ensure the safety of operators and inverters, it is
necessary to be operated by qualified professional electricians. The
following are special considerations when wiring :
3-1 Peripheral device connection
•
Make sure the input power is off before wiring.
•
The ground terminal of the inverter must be reliably grounded.
•
Verify that the rated voltage of the inverter matches the AC power
supply voltage.
•
The power cable must be connected to the R, S, and T terminals of the
inverter. The motor cable should be connected to the U, V, and W
terminals. Do not connect the fault. Otherwise, the inverter will be
damaged internally.
•
Confirm that the terminals and wires are reliably connected, and the
screws of the main circuit terminals are secured.
•
Do not touch the main circuit terminals, otherwise there is danger of
electric shock.

the AC drive because such operation reduces
the service life of the AC drive.
