INSTALLATION
OJ GreenZone™ Module MP-Bus should be fitted to a standard 35 mm DIN rail mount-
ed in an enclosure corresponding to the installation site classification (see fig. 2 for unit
dimensions). The unit itself is classed as IP20 and ETT-KH from OJ Electronics can be
used for such covering purposes. The most practical location will often be in the vicinity
of other components, valves, sensors, etc. associated with the VAV zone. An overview
of the physical configuration of the system is given in fig. 19.
An ideal location would be above a suspended ceiling panel. OJ GreenZone™ Module
MP-Bus must be provided with a 24 VAC, +/-15% power supply and is therefore
equipped with looping terminals (max. 1.5 mm
2
) for the purpose (see figs 8 and 9).
Other connections are made by means of a combination of RJ12 connectors and screw
terminals for connecting wires of max. 1.5 mm
2
cross-sectional area (see fig. 3).
Connections and indications
(see overview in fig. 1)
In fig. 3, all connectors are marked with a letter (A – P).
See below for descriptions of electrical connection of the various components, inputs
and outputs, and other signals and indications of the OJ GreenZone™ Module MP-Bus.
