Quick Guide of SMA
1.Preface
Thank you for choosing the SMA series of economic AC drive.
Before using the AC drive, please read the instructions care-
fully so that you can install and use the machine correctly, to give
full play to its functions and ensure safety. Please save this ins-
truction perpetually, for later maintenance and overhaul. AC drive
is the power electronics product, so, for your safety, please be
sure to install, debug and adjust parameters by qualified professio-
nal electrical engineers. The symbols such as danger and ！Note in
the instruction remind you of the safety precautions when carrying,
installing, running and checking the AC drive. Please operate in
accordance with this instruction, to make the AC drive safer.
If you have any doubts, please contact our agents all over the
country, and our professionals are willing to serve you.
This instruction is subject to change without notice.
Dangerous or wrong operation may cause casualties.
Danger
● Be sure to turn off the power supply before implementing the wiring.
● If the charging indicator doesn't go out after the AC power is cut
off, it means that there is still high voltage in the AC drive, which is
very dangerous, and do not touch the internal circuit and components.
● Do not check the parts and signals on PCB when running.
● Do not disassemble and change the internal wiring or components of
the AC drive by yourself.
● Please be sure to connect the ground end of the AC drive to the
ground.
● It is strictly forbidden to refit and replace the control panel and
components privately, otherwise there will be dangers such as electric
shock and explosion.
！ Note that it may cause damage to transducer or mechanical
system under wrong operation.
！Note
● Do not carry out voltage test for the components inside the AC
drive, because these semiconductor parts are easily subject to damage
under high voltage.
● It is strictly forbidden to connect the inverter output terminal
U.V.W to the AC source.
● The main circuit boards of CMOS and IC are susceptible to impact and
damage of static electricity, so do not touch the main circuit board.
● Only qualified professionals can install, debug and maintain the AC
drive.
● If the AC drive is scrapped, please treat it as industrial waste,
and it is strictly forbidden to burn it.

3.Storage and installation
3.1 Storage
●The AC drive should not be stored for a long time. Long time of
storage will lead to the deterioration of electrolytic capacitor. If
long time of storage is needed, it is necessary to ensure to be
electrified at least once a year, with the electrified time of at
least 5 hours, and the voltage must be slowly increased to the rated
voltage by the voltage regulator.
This product must be placed in the packing box before installa-
tion. If not for use, please pay attention to the following items
when storing:
●It must be placed in a dustless and dry place;
●The temperature of the storage environment should be from -20℃
to +65℃；
●The relative humidity of storage should be between 0% and 95%,
with noncondensation;
●There should be no corrosive gas and liquid in the storage
environment;
●It’s best to put them on shelves and store them in proper pack-
ing;
3.2 Installation site and environment
Please install the AC drive in the following sites:
●The site with ambient temperature of -10℃～50℃, and good venti-
lation;
●The site with no dripping and low humidity;
●The site with no dripping and low humidity;
●The site without sunlight, high strength and serious dust falling;
●The site without corrosive gas and liquid;
●The site with less dust, oil and gas and metal powder;
●The site with no vibration, which is easy for maintenance and
check;
●The site with no electromagnetic interference;
Other functions Automatic voltage regulation (AVR),deceleration stop or
free stop, DC brake, carrier adjustable, up to 10 KHz,etc.

3.3 Installation space and direction
●In terms of convenience for cooling and maintenance, there must be
enough space around the AC drive, as shown in the figure:
●In order to obtain the good cooling effect, the AC drive must be
installed vertically, and ensure the smooth flow of air.
●If the installation is not stable, install it after placing a flat
plate under the base of the AC drive. If installing it on the loose
surface, the stress may cause the damage of the main circuit parts,
and the AC drive will be damaged.
●The wall for installation should use the non-flammable materials
such as iron plate.
●If several AC drives are installed in the same cabinet, install
them in the up and down direction, and attention should be paid to
the distance among them. In addition, please add the diversion
baffle in the gap, as shown in the figure.
