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.
