1. Safety Instructions
SAVE THESE INSTRUCTIONS. This manual contains important
instructions that should be followed during installation and
maintenance of the ATS.
1. Do not disassemble this product without a technician from the original
manufacturer or authorized distributor. Doing so voids your warranty and is
also a shock hazard.
2. Every component of this product is checked for high specification standards.
Performance maintenance or parts replacement should only be done by a
qualified technician or authorized distributor.
3. Do not install the product at the following locations without a qualified
technician:
4. Medical equipment directly related to human life preservation;
5. Equipment on elevators or rapid transit systems related to personal safety;
6. Critical computing hardware for public systems;
7. Other equipment similar to the ones mentioned above.
8. Please discuss with your distributor before installing the product at the
locations mentioned above. Special considerations and designs are required
for the operation, setup, management, and maintenance of critical equipment
and emergency backup power generators related to personal safety and public
facilities.
9. Do not place vases or other water containers on top of the main unit. Water
spilled into the machine may damage internal components and pose a shock
hazard.
10.Using this product in locations with sparks, smoke, or natural gas may result in
arcing, personal injury, and fire hazards.
11.The operating environment and storage method affects the product lifespan
and malfunctions. Thus, please keep the product away from the following
operating environments:
12.Locations specified in the operating manual as high temperature, low
temperature, and high humidity (temperatures outside -5 to 40℃and relative
humidity outside 30% to 90%);
13.Locations with sparks;
14.Locations with dust, corrosive material, salt content, or flammable gas;
15.Outdoors.
16.Immediately stop using this product in the event of abnormal sounds or odors.
Contact your distributor for maintenance.
17.Improper grounding results in electrical leakage. Please make sure your AC
input power is properly grounded.
18.Please confirm the input voltage does not exceed the rated capacity of the
ATS.

2. Product Description
The ATS (Automatic Transfer Switch) features two independent power supply
circuits supplying power to the load (as shown in Figure 1 below). In the event of a
power failure in the main circuit, the ATS automatically switches to the other
circuit to supply power to the load. The ATS automatically switches back to the
main circuit after power is restored. In addition, the ATS also provides user
configurable power states (voltage or frequency) for the ATS switching condition.

3.4. Product Installation and Operation
3.4.1. Installation Procedure:
1.Open package and note the packaging layers. Keep the box and packaging
material in case further transportation is required.
2.Check for damage to the ATS from shipping and handling. Please contact your
local distributor if the product is damaged.
3.Check the input power cable/socket and output socket of the delivered ATS
model with your order.
4.Affix the backplate (Figure 1) onto the ATS (Figure 2). Affix the ATS onto the
frame of the chassis (Figure 3).
5.Insert the load plugs into the ATS sockets labeled "OUTPUT" and spreading
them as evenly as possible.
6.Check that the total load does not exceed ATS specifications (e.g. voltage,
current).
7.Supply power to the ATS. The ATS automatically boots up after 1 second and
supplies the capacity power to the connected load.

3.4.2. Boot up
Once input power is connected, the ATS automatically boots up. The LCD display
during boot is as shown in Figure 4 and all LEDs ( , , ) are lit.
LCD display is as shown in Figure 5 after boot up, only the LEDs for Power A
() and Power B ( ) are lit.
Figure4 Figure5
3.4.3. Switch input source
This products supports manual switching between power supplies as instructed
below:
Push and hold the button for 2 seconds until you hear two short beeps.
The system then needs to reconfirm the power transfer (LCD display as shown in
Figure 6), so push and hold the button for 2 seconds to confirm. The
system will switch to the other input (LCD display as shown in Figure 7) if the
power supply is normal, otherwise the transfer is not made and a warning is
shown (LCD display as shown in Figure 8).
