NRT407 manual Part II Installation 15
Chapter 5 Installation preparations
Different versions of terminals and pins
The old terminal type is dark grey and intended for 1.3 mm pins. The new terminal type is
light grey and intended for 1.1 mm pins. Confusion between a new and old bottom plate may
lead to deficient contact. Therefore, it is important to use an old electronics unit together with
an old bottom plate and a new electronics unit together with a new bottom plate.
Figures 1 and 2 show an example of the difference between the old and new terminal types
(the number of terminals depends on the NRTs model).

Using labels
On the back of the electronics cassette, there is a set of labels which makes it easier to install
large numbers of NRT controllers. By using the labels as carriers of information for the
installation engineer, much time will be saved and you can keep wiring errors at a minimum.
Figure 3. Label on the back of the controller
The three-piece label can be split and the parts can be fastened to the installation drawing
and the bottom plate of the controller. The label carries information on the communication
address etc., and has a note area where you can enter a reference number to the connection
diagram.
The address on the sticker has a different meaning depending on what communication
protocol is used.
