OZ 3.0 Installation Guide
5.2 Control Panel and the Ozone Modules data wiring
Three cables are connected to the Control Panel. Data cable (3x0,25mm2) for communication between
Control Panel and EOZ unit, I/O cable (5x0,5mm2) for connecting to the building automation and LAN cable
to access the Control Panel via internet.
Ozone Modules are connected sequentially (”daisy-chained”) from the Control Panel to the nearest Ozone
Module, then to the next module and so on. However, please note that although the physical cabling is
”chained” from one device to the next, the data cables are connected together in a parallel format. That is,
similar terminals between devices are connected together; there are no specific ”in” or ”out” data terminals
on the various components.
Maximum limit for the number of Ozone Module connected to the Control Panel is 99 and maximum length of
the data cable is 500m. However, it may be advantageous to have multiple Control Panels in larger facilities.
Cable bushings come preattached inside the supply chambers.
*3x0,25 mm2 or another shielded data cable with at least 3 conductors.
Data terminal A-, B+ and C (GND) are connected similarly between the Control Panel and each Ozone Module.
Note the cable colors used on each terminal to ensure all devices are connected similarly.
As stated above, the data cables are typically run through the facility in a daisy-chained format, although the
individual communications wires themselves are connected in parallel. In this way data communications
between devices will remain active even in the case one of them is powered off, malfunctioning, or unplugged
and removed.
Thus, each A-, B+ and C data wire leading
in from devices on both sides of any Ozone
Module in the chain should share the same
terminal screw in its respective connector. In
this way the three extra unused terminals just
below on the connector block can be reserved
for future expansion.
