Installation guide

Important! During installation and operation, observe the general rules of electrical safety regarding the use of electrical appliances, as well as the requirements of regulations on electrical safety. It is strictly forbidden to disassemble a device to which any conductors are connected!

Atom series controllers require pre-configuration:

1. Installation

Install the controller and power supply to the DIN rail. Make sure there are no signs of mechanical damage or condensation. If necessary, install additional switchboard equipment - contactors, circuit breakers, power supplies and other automation devices.

2. Power supply

Connect the power supply to the mains via the circuit breaker. Connect the power supply output to the controller's power connector.
Controller power connectors, sensor power outputs and load control outputs for easy installation are made in the form of removable connectors with screw terminals.


Important! Although the controller has built-in protection against incorrect power connection, and in this situation will not fail, we recommend that you pay attention to the correct polarity when connecting

3. i3-NET

If your system uses multiple controllers, connect them to a i3-NET network. Install the end terminators included in the equipment kit at the ends of the bus.


4. Connecting inputs

Connect sensors, switches and other devices to the inputs of the controller. Connectors with screw terminals are used at the inputs of the controller, which ensures the convenience and reliability of connecting conductors with a cross section of up to 1.5 mm2.

Important! The inputs are numbered and on each input there is a marking of the "common" output (marked with the letter "G") - this is a common contact, it is connected to the "minus" of the controller's power supply. All common contacts are interconnected, so when connecting switches with a multi-conductor cable, if necessary, it is enough to use only one connection to the “G” terminal.


5. Connecting outputs

Connect the devices controlled by the controller to the outputs. In the device, the outputs are combined into a group, the common output of the group is marked COM, and all outputs are numbered. Each group is implemented in the form of a 4-pin connector and is designed for connecting conductors with a cross-section of up to 2.5 mm2.
Examples of connecting loads to Atom Extension AD4 controllers are shown below.

OUT1-OUT4 - dimmers designed for controlling lamps with a supply voltage of up to 250V and a power consumption of up to 200W per channel.


6. Done. Turn on the power

Important! Check all connections. Make sure that the power supply, inputs and outputs are connected correctly.

List of typical problems and their solutions

  • LED indicators do not light

    1. Check the supply voltage on the controller2. Check the polarity of the power supply

  • The device is turned on but not in the application settings

    1. Make sure Wi-Fi and bluetooth are turned on on your smartphone or tablet2. Verify that the home network password is specified correctly in the controller settings3. Check the correct connection of the i3-NET bus
