ELECTRICAL INSTALLATION OF THE SYSTEM
Read the instructions carefully before installing and using this appliance
The manufacturer cannot be held responsible and declines all responsibility in case of damages suffered by persons or
property as a result of improper use or incorrect installation of the products affected by this warning.
These materials should be installed by suitably qualified persons.
Bad connections may wire to the destruction of the modules, valves and sensors.
Each system (one system = one VMX Main module) should have its own circuit breaker and be connected directly to the
electrical switchboard especially with a view to enabling operations and maintenance.

Note: the voltages on the bus wires (BUS-, BUS+ and V+) do not present any danger to persons (less than 12 V).
Before starting installation
·for each part, locate the positioning for each component and the duct passages, taking special care to limit the loss of airflow loads and the length of
the wires; the sensors should be positioned and distributed so as to provide a relevant measurement of the parameter(s) transmitted.
·position the components so that the required lengths of the wires can be determined.
·do not connect to the power supply before installation has been completed.
5.1. WIRING
The main advantage of the bus solution for the power supply implemented in the VMX system is that the wiring is so simple; only two wires are required
to ensure the power supply and communication with the different components.
Characteristics of the wires
Maximum lengths for wires between the
main module and the components
Section: 1.5 or 2.5 mm²
The wiring used should comply
with the regulations in force.
For each component
Connect all the black terminals together and the orange terminals together.
For the CO
2
sensor and for motorized valves
In addition to the orange and black terminals, connect the V+ terminal on the main module to the CO
2
sensor*.
Examples of wiring diagrams can be found on the following pages.
Each of the components of the VMX system is connected using 2 or 3 wires. The orange wire is connected to the orange terminal, the black wire is
connected to the black terminal. For the motorized valve, as for the CO
2
sensor, is connected to the V+ (use a specific colour for this wire).
