Safety instructions
Danger
Dangerous high voltages exist inside this machine. Do not open any covers of this machine unless authorized
and done by trained technicians. Otherwise, electrical shock to persons may happen.
In case the machine needs to be moved or re-wired, all electricity to the machine must be disconnected and
removed. After electricity is removed, please wait for at least 20 minutes before touching any live parts of this
machine or electrical shock may occur: the electrical charges on the bulky capacitors inside the machine need some
time to be fully discharged.
For optimal safety protection to the users, this machine must have solid connections to the earth. Do not use
this machine if it is not grounded.
In case of fire, use an extinguisher with powder chemicals instead of liquid agents. Electrical shock may occur
if liquid extinguishing products are used.
Any foreign objects and/or liquid are strictly prohibited from entering to the inside of this machine.
Caution
Storage and operating environment have a certain degree of influence on the life and reliability of this product.
Therefore, avoid placing and/or operating this machine in environments with the following:
(i). Having extreme ambient temperature or humidity that exceeds the allowable limit stated in the
specification, temperature: 0℃～45℃, humidity: 0～90%.
(ii). Having direct sunlight exposure, or being near a heat source.
(iii). Places that tend to be vibrated or hit by other objects.

Chapter I Product Introduction 1
Chapter I Product Introduction
AFV series power supply is a programmable power supply for grid simulation. By virtue of
advanced SPWM technology and direct digital frequency synthesis (DDS) waveform technology,
the power supply has stable output frequency and good continuity. AFV series power supply not
only can provide continuous, pure and stable sinusoidal voltage, but also can achieve local control
and remote control by the user’s PC for the power supply system through internal control and
communication modules. At the same time, the internal electronic circuit can quickly detect over
current, overload, overvoltage and output short circuit, automatically protect and cut off the output,
and send out an alarm. The integrative laminated busbar technology and modular configuration are
applied in the power supply inverter unit to improve reliability and stability. The touch screen
display and control are utilized for easier operation.
The main performance characteristics of AFV series variable frequency power supply are as
follows:
By virtue of advanced SPWM technology and direct digital frequency synthesis (DDS)
waveform technology are used, the power supply has stable output frequency and good
continuity;
The patented inner loop energy-saving test design is used to save the energy consumption;
High precision settings and output;
Comprehensive and stable protection, perfect self-diagnostic maintenance function and
higher system reliability;
The laminated busbar structure is used to effectively reduce the inductance of the inverter
circuit and improve the reliability of the inverter;
Intelligent fan speed regulation control is used with built-in dust filter to achieve efficient
heat dissipation and effective protection function under harsh environment;
Communication interface: Communication way RS485 (standard configuration) and
Ethernet (optional configuration);
Running event recording function is provided, and the number of records may be up to 255.

3.1 Transportation precautions
Chapter III Transportation and Installation 4
Fig. 3-1 Schematic diagram of transportation
Because the equipment is heavy, the lifting operations need to be slow during the
transportation of the forklift, so as to prevent damaging the equipment itself or the surroundings.
During the transportation that the equipment needs to be fixed firmly to prevent the equipment
from sliding or dumping due to vehicle bumps. Although the shockproof packaging was design in, it
is recommended that more cautious should be taken in consideration in case of driving on bumpy
roads.
3.2 Unpacking inspection
When open the wooden boxes which contain the equipment, pay extra attention on handling
it due to heavy weight consideration. Avoid dropping or dumping occurs.
Before turn on the equipment check the equipment condition if any damage was found. You
should inform service staff of our company to take proper treatment.
Check the accessories according to the delivery accessory list. If any accessories are missed,
please contact the customer service.

3.3 Installation environment requirements
When selecting the installation environment, the following matters should be followed:
1) Install the equipments in indoor and keep the environment air flow. Try to keep the
equipment air inlet/outlet free of dust;
2) The ground on which the equipment is installed should have sufficient strength and flatness,
and the equipment shall not shake after the installation is in place;
3) The equipment adopts incoming line and outgoing line. Therefore, it is recommended to
arrange these lines and cables connected to the external from the cable trenches, so as to
facilitate the installation and maintenance;
4) Where the equipment placed should give sufficient space to allow the heat which produced
by the equipment to radiate. (see Fig. 3-2) At the same time, do not cover the air inlet of
the front panel, for allowing heat to radiate;
5) Do not use the equipment in the environment with dust, volatile gases, too high saline matter
or corrosive substances, because this may affect the product life;
6) Do not place the equipment in the environment with too high temperature or humidity; and
away from water, flammable gases, corrosive or heat sources and avoid direct sunlight;
7) Use correct power distribution way to guarantee the safety of the equipment and user‘s
equipment.

Chapter V Operation
5.1 Initial power-up of system
The input and output wirings should be properly connected according to the input and output
connection way in Section 3.3. If the system is started, the main engine fan will start to operate, the
panel display screen is on and the main interface is entered, indicating that the start-up is normal
and the parameter setting can be conducted for the machine.
Note: If there is an external load, the load switch should be disconnected first, and the input
switch should be connected (it needs to confirm whether the electric power of the input terminal
row is normal before the input switch is connected).
Users can enter the application interface by clicking “Application”. Users can set the output
voltage and frequency value, press the [Operation] key after the setting is completed, and then click
“Meas.” to display the actual output each phase voltage, current, frequency, etc.

Chapter VII Maintenance
Extreme temperature, high humidity, heavy dust, chemicals pollution and physical vibration
all could impose negative impacts on the life and reliability of this machine. Nevertheless, the
nature aging of all the electrical and mechanical components would further cause it to be more
vulnerable to all kinds of faults. Therefore, routine and periodic maintenance are necessary and key
to the reliability of this machine in the long run.
Only authorized and trained technical professionals are allowed to carry out the
maintenance on this machine.
7.1 Routine maintenance
First, the daily operating environment must comply with the requirements stated in this user
manual. Routine inspection on the environment and the machine should be checked on a regular
basis. All the environment data, the operating status and the parameters set in the machine should
be recorded as well. It is best to have a detailed and accurate “machine usage log file” for all time
reference and maintenance.
Abnormal phenomenon on the machine can be detected by the routine inspection and
maintenance. Once observed, the users should try to identify the root cause first and remove the
problem immediately. Call our customer service if you are not able to identify the cause, or not able
to remove the problem. The earlier the problem can be removed, the longer the life of the machine.
Checking items in the routine maintenance are listed in Table 7-1.
