GENERAL INFORMATION

If you have any questions or doubts during the installation process then please feel free to get in touch with our support team. Our technicians are always happy to help.

Safety Notice
We strongly advice that you seek the advice of a qualified electrician before carrying out any work on your wiring. The Miniserver uses both low voltage and mains, which means that certain work should only be carried out by a qualified individual. Whenever work is done on the cabling of the Miniserver please ensure that power to the Miniserver is removed. Damage to components can occur if this is not observed.

WIRING OF THE MINISERVER

This video shows you how to quickly and easily wire the Loxone Miniserver and an Extension. We take you through the whole wiring process from boxed to powered up!

WIRING BASICS

The wiring in your home can be compared to the nervous system in a human body, without it the automation system can neither sense nor act. Whilst nature has perfected its signalling system over thousands of years, home automation has only been around for a few decades. No one knows where this journey is taking us and there will be lots of new switches, sensors, light-fittings and much more to come.

It is therefore important to think ahead and future proof your installation. The wiring is the backbone of an automation system and whilst it is easy to replace a motion sensor, a switch or a light fitting it is much harder to replace the cables that are plastered into your walls.

We therefore recommend that you use cables that have stood the test of time and have become industry standards. For the sensor side, which is low voltage we recommend you use a data cable, i.e. Cat5e/6/7. A Cat cable can be used for various applications, PC Networks, volt free contacts, serial communication, bus systems, and more. Please note that it cannot be used for 230V loads! For load switching you will have to use appropriately rated power cables, i.e. 1.5mm, 2.5mm, Twin & Earth etc.

The system will be at its most flexible and future proofed if the cables are run as a star from a single point (the star-point) to sensors and actuators. To keep cable runs from getting too long multiple start points can be used, but please consider running a few cables between start points to link them.

IMPORTANT FACTS:

  • All our devices are powered using 24V DC, so using 24V sensors is desirable
  • Wire back to a central point
  • If you use multiple start points and have got Extensions around the place, then the maximum allowable length of the Loxone Link is 500m
  • The Link has to be terminated at the last device with a 120 Ohm resistor, if no Extensions are used then no resistor should be used
  • The maximum bumber of Extension on the Loxone Link is 30.

SWITCHES

With Loxone you can make any conventional switches become much more useful and multi-functional. As long as the switch provides a contact closure it can be wired into the system and then in software can have as many functions as you want it to. We recommend using retractive switches due to the ability to cycle through clicks, double click etc.

CABINET LAYOUT

In the diagram below you can see how you can optimally arrange a mains distribution board and a sub-distribution board. In each cabinet there are separate power supplies for the Loxone equipment. We also recommend using additional power supplies for sensors such as presence detectors, as well as for powering LED tape. This is to improve the reliability of your system.

Please note that all power supplies for the Loxone equipment must have their GNDs commoned. To do this you can use spare pairs in the CAT cable for the Loxone Link between the two boards.

To prevent wiring clutter we recommend that you use DIN rail terminals for the wiring of all inputs and outputs. Make sure to plan some spare inputs and outputs as it is easy to miss something at this stage. So the wiring is neat we also recommend using cable trunking. You can see this in the diagram around the outside of the cabinet. Sensors have been wired down the left hand side, and mains cable down the right hand side. To allow this to work, there should be a distance of about 3cm between the extension terminals and the cable trunking.

When connecting the Loxone link and other data connections you should use a twisted pair of your panel wire.

Make sure to use a cabinet large enough to hold all the equipment with space to spare for future expansion.

SWITCHES

With Loxone you can make any conventional switches become much more useful and multi-functional. As long as the switch provides a contact closure it can be wired into the system and then in software can have as many functions as you want it to.

CONNECTING THE MINISERVER TO A POWER SUPPLY

  1. Connect the DC output of the 24V power supply to the power terminals on the Miniserver.
  2. Connect the 24V power supply to the mains only once you have finished the rest of the installation.

Whenever work is done on the cabling of the Miniserver please ensure that power to the Miniserver is removed. Damaged components can occur if this is not observed.

Wiring example for connecting the Miniserver to several power supplies.

You must connect all the power supply GND’s together. Otherwise problems may occur due to difference in potential.

CONNECTING ONE OR MORE EXTENSIONS TO THE MINISERVER

  1. Connect the power terminals of the Miniserver to the power terminals on the Extensions.
  2. Connect the Loxone Link connector of the Miniserver with the Loxone Link connector of the Extension.
  3. Terminate the Loxone Link at the last Extension with a 120 Ohm resistor (comes with your Miniserver package).

Note: If no Extension is connected there is no need to use a 120 Ohm resistor.

CONNECTING ONE OR MORE EXTENSIONS TO THE MINISERVER GO

  1. Connect the Ground terminal of the Miniserver Go to the power terminals on the Extensions.
  2. Connect the Loxone Link connector of the Miniserver Go with the Loxone Link connector of the Extension.
  3. Terminate the Loxone Link at the last Extension with a 120 Ohm resistor (comes with your Miniserver package).

Note: If no Extension is connected there is no need to use a 120 Ohm resistor.

Wiring A Miniserver Go To A Loxone Extension

The power should be removed whenever working on the installation, but that if this is not possible then ensure that the blue Link connector is always unplugged before the power connector to prevent damage to the communication circuitry.
