OZ 3.1 Installation Guide
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.
If applicable, install the I/O data cable for your building automation system or for future upgrades.
Connect the five (5) terminals DI1, DI2, DO1, DO2 and COM+ and mark the other
ends of the wires within the
junction box with their corresponding terminal assignments
