1. Introduction
This ATS 16 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 16
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 16 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 16 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 16 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 16 is purchased.

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 16.
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 16 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.

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.
