Chapter 5 Preparations for installation
Using labels
A series of labels are located on the back of the electronics cassette, which simplify
extensive installations of NRT controllers. By using these labels to convey information to the
individual responsible for the physical installation, it is possible to save much time and to
minimise errors during wiring.
Figure 2. Label on the back of the controller
The three-piece label can be divided and its parts attached to the building drawings and the
bottom part of the controller. The label contains information regarding communication
address etc., together with a field for notes where a reference number for the wiring diagram
can be entered.
Depending on the communication protocol used, the address on the label can mean different
things.
Example 1 If the label address is 191:183, the following addresses are used for the different
communication protocols:
PLA=191, ELA=183.
Modbus: Address=183.
BACnet: Device ID=191183 (the 4 low digits=1183, the 3 high digits=19), MS/TP MAC
address=83.
