1. Introduction
This ATS-30A product is designed with two independent power inlets to supply
power to the load from a primary power source. Should primary power source
fail, the secondary will automatically back up the connected equipment without
any interruption. The transfer time from one line to another is seamless to the
connected equipment. After switching to a secondary power source, the ATS can
also switch power back to the primary input when power to the primary input is
restored.

3. Important Safety Warnings
Before using the unit, please read all instructions and cautionary
markings on the unit, this manual and the batteries.
WARNING!! The ATS must be connected to earth when in use.
In line with current regulations, only use the cables that have been supplied with
the machine. The power supply socket must be easily accessible to the operator.
WARNING!! The ATS has been designed exclusively to operate indoors. It is
advisable to install it in areas where no inflammable liquids or gases, or other
harmful or noxious substances, have been stored.
ATTENTION!! A soft damp cloth may be used to clean the outside of the
machine (always with the system disconnected from the mains power supply and
users).
Do not use any type of solvent as this may damage the external finishing of the
machine.
ATTENTION!! The ATS has been designed exclusively for professional use.
NOTE: These instructions may be modified by the wiring regulations in force in
the country where the ATS is purchased.

5. Installation
NOTE: Before installation, please inspect the unit. Be sure that
nothing inside the package is damaged.
Mounting the Unit
The unit can be mounted in a standard 19" rack. Fasten the mounting brackets to
the unit using the screws provided. With brackets attached securely, users can
mount the unit in a standard 19" rack as shown below.
NOTE: If the temperature around the unit will rise above 40 °C, ventilation is
required
Connecting the Unit
Step 1: Take out the terminal cover
by removing four screws.
Step 2: Fasten the input/output
wirings through the cable gland.
Step 3: Fasten the terminal cover and
cable gland to the unit. Then,
customer can plug the user load to the
output 10A (“Output 3”) or 16A
(“Output 2”) sockets depending on
user’s requirements.

6. Operation
Power On/Off
Put the input power switch in “ON” position. The output will then be supplied by
the source set as selected.
Setting priority of power source
It is possible to set the power source preference to supply the output by pushing
the button of “source preference selector”. The default power source is “Source A”.

Contact Ports
The contacts port is formed using six (6) pins numbered from left to right (see fig.
1), which can be connected to an external monitoring system (such as a BMS) in
order to monitor the operational status of the ATS.
The external equipment must respect the voltage and current characteristics of
contacts port.
Fig. 1: Focus on contacts port.
The contacts port provides the following pins:
•Pin 1: common contact.
•Pin 2: “Source B” active contact (if the contact between “pin 1” and “pin 2” is
closed, output is supplied by “Source B”).
•Pin 3: “Source A” active contact (if the contact between “pin 3” and “pin 1” is
closed, output is supplied by “Source A”).
•Pin 4: “Source A” status OK contact (if the contact between “pin 4” and “pin 1”
is closed, “Source A” is present and regular).
•Pin 5: “Source B” status OK contact (if the contact between “pin 5” and “pin 1”
is closed, “Source B” is present and regular).
•Pin 6: Status OK contact (if the contact between “pin 6” and “pin 1” is closed,
ATS functioning status is regular).
The following diagram shows the functioning of the contacts port.
Fig. 2: Contacts port basic diagram.
ATTENTION: The pins of the contact port are able to carry maximum current of
8A and maximum voltage of 250Vac.

8. Trouble Shooting
Use the table below to solve minor problems.
Problem
Possible Cause
Solution
The ATS with the
mains voltage
present, does don’t
turn on.
(The LEDs does
not flash and no
alarm sounds.)
No connection with
input plugs
Connect the mains to the input plugs
as indicated in the installation section.
Input switch in
“OFF” position
Turn the input switches in “ON”
position.
Input power failure
Check that the mains voltage is present
or check if the UPS supplying the ATS
is powered on.
Protective device
upstream activated
Reset the protective device. Warning:
check that there is no overload or
short-circuit at the output of the UPS.
The load is not
powered.
No connection with
output sockets
Connect the load to the output sockets
Intervention of
10A/16A thermal
protection
The thermal protection device will
operate in the event of a short circuit
or overload on one of the 10A/16A
output sockets. The thermal protection
can be reset by pushing the button in
which will result in the power being
reconnected to the load. Therefore
prior to attempting a reset of the
thermal protection, please check the
connected loads rating and/or
determine if there are any problems.
Then once reset, reconnect each load
one at a time to ensure no problems
exists.
The display shows
nothing or
provides incorrect
information.
There is power
supply problem in
display.
Shut down the ATS completely and
wait for a few seconds.
Switch the ATS on again, if the problem
persists, contact the nearest technical
support centre.
The display is off
but the load is
powered.
There is power
supply problem in
display.
Contact the nearest technical support
centre.
If there is any abnormal situations occur, which doesn't list above, please call the
service people immediately for professional examine.
