Description

In a regular Niko Home Control installation the integrated power supply of the connected controller ensures the 26Vdc voltage on the bus, the modules and the control elements. An additional power supply is only necessary for large installations with many users. Several additional power supply modules can be connected in parallel in one single installation.

Overview


Dimensioning

Rule of thumb

To calculate the required amount of additional power supplies, you can use the following rule of thumb: up to 24 cabinet modules and 70 controls (of which 20 with indication LED) per power supply. The integrated power supply of the connected controller counts as one power supply. Depending on the size and layout of your installation, you will need to install no, one or several additional power supplies.

This rule of thumb leaves a margin for error.

Exact calculation

Each control and module consumes a specific amount of energy. This consumption is expressed in points (see tables on the following pages). The first 800 points are absorbed by the integrated power supply in the connected controller. An additional power supply is needed for every additional 800 points. Add the points of all the controls and modules of the installation, divide this sum by 800 and subtract 800 points. The result is the required number of additional power supplies.

Installation

Wiring diagram

Each extra power supply has a capacity of 10 W. Determine the exact number of extra power supplies required prior to commencing the installation process. See Dimensioning.

Follow the steps below to connect and mount a power supply module:

  1. Click the extra power supply onto a DIN rail.
  2. Connect all four connection terminals (+, –, B1, B2) to the corresponding connection terminals of the connected controller, rail coupler or the power supply on the previous and next rails.
  3. Each module is fitted with a sliding contact. Slide the sliding contact to the right until it clicks into the next module. This will ensure that the bus and the power supply voltage are connected.
  4. Connect the L phase wire and the N neutral conductor to the L and N screw terminals respectively.

Error codes

When the module is functioning properly, the STATUS LED will light up in TEST mode only. If one or several errors occur, the LED will blink to indicate the error code of the error with the highest priority. The table below provides an overview of all error codes.

Press the TEST button on the controller to activate TEST mode.
