INSTALLATION

OJ GreenZone™ Module M should be fitted to a standard 35 mm DIN rail mounted
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
M must be provided with a 24 VAC, +/-15% power supply and is therefore equipped
with looping terminals (max. 1.5 mm
tions are made by means of a combination of RJ12 connectors and screw terminals for
connecting wires of max. 1.5 mm
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 M.
Connectors "A – B – C" – Modbus actuators (see figs 3 and 14)
Modbus actuators are connected by means of RJ12 connectors.
Up to three Modbus actuators can be connected and VAV damper motor, cooling valve
or heating valve may be freely chosen. The maximum distance between OJ Green-
Zone™ Module M and the actuators is 30 m. OJ GreenZone™ Module M can itself
ascertain which actuators are connected if each actuator has been programmed with a
Modbus address in accordance with the following table.
