Connection Terminals
The 4-pole and the 2-pole connector terminals required for the room bus and the 24Vdc power supply
are not supplied with the IP room controller. The connectors are available as accessories and must be
ordered separately.
5.5.1 4-Pole Connector Terminal (NICT-4AA)
Figure 28. 4-pole connector terminal
The 4-pole connector terminal is used for connecting the room bus. It has a screw-less “spring-cage”
connection technique and each terminal has two connection points.
The designation of the required four wires is as shown in the following illustration.

Preparing the Wires for the 4-pole Connector Terminal
The 4-pole connector terminal has four terminals with two connection points at each terminal. Each
connection point accepts one solid wire of maximum wire size 20 AWG (0.8mm).
To connect the wires first strip the jacket from the cables and pull the wires through the housing leaving a
length of 6in (150mm) free, as described in section
5.3, Preparing the Room Bus and Power Cables
. Then strip 0.25in (6.5mm) of the insulation from the end of each wire which is to be
connected.
Figure 30. Stripping the wires for insertion in the connection terminal
After stripping the wire to expose 0.25in (6.5mm) of conductor, insert the wire in the appropriate
opening of the connection point by pressing the wire firmly into the terminal, as illustrated below.
Note:
Each connection point in the connector terminal accepts only one wire. Maximum
wire size 20 AWG (0.8mm).
