2 Installation and connection
Basic instructions
Always follow these instructions during the installation:
 Make sure you meet the actual standards and rules and all regional and state regulations.
 Always turn off the power supply before any manipulation (mounting / demounting).
 Use a wire with appropriate wire gauge.
 Do not exceed screw torque of removable screw connectors.
 Follow installation and operating conditions.
 Keep the cabling as short as possible. If longer cables are necessary, you should use shielded
versions. You should always route your cables in pairs: i.e. one neutral conductor plus one
phase conductor or signal line.
 Always keep separate:
o The AC wiring
o High-voltage DC circuits with high-frequency switching cycles
o Low-voltage signal wiring
 Ensure that the wires are installed with appropriate strain relief.
 Installation of the device must be performed in stable and closed distribution box.
Note
Neuron devices may only be installed and wired by skilled personnel who are familiar with and follow
relevant rules, regulations, and standards.
Warning
It’s an open device. Death, serious bodily injury, or considerable property damage can occur. The box,
in which Neuron device is installed, must be accessible only with a key. Access to the key must be
allowed only to authorized personnel.
2.1 Neuron product structure
Each Neuron product is divided into 1 to 3 groups which depends on specific type of product. Groups
are numbered from right to left in the direction from the main group (1). Each group consists of inputs,
outputs, or communication channels – these are numbered from left to right separately for each group.
Some advanced features are only available to specific group. Each group features its own processor,
which handles events and monitors communication with the main processor. Groups do not
communicate with each other. Connectors of given group are always divided according to the purpose
to avoid possible mistake. The purpose of each screw connector is described atop the product case.
The position of connector corresponds with the position in the description.
Note
Screw connectors are numbered like DiX or DiY.X. – the X stands for the number of input / output while
the Y stands for the group number. If no group number is stated it is always the group 1.
