2.3 Wiring and connections.
2.3.1 Mains power.
•Be sure that the mains voltage stated on the unit complies with the local standard before connecting the Intellivox to the mains supply.
The maximum power consumption of the Intellivox-2c model is 450 VA, this figure however is different from other models (refer to the appropriate datasheet). The Intellivox is equipped with a 3-pin IEC type mains inlet / fuse holder. If the fuse needs to be replaced only replace with the same value. The IEC cable socket which is supplied with the unit is only suited for use with stranded wires. The preferred (and most straight forward) solution is to feed the Intellivox from a mains power outlet situated nearby the unit using an ‘off the shelf’ 3 x 0.75 mm2 (AWG 18) IEC mains cable. If the mains outlet is located directly behind the Intellivox it should be recessed to be able to mount the unit flat to the wall.
In case it is necessary to make a connection from massive to stranded wires, the use of an appropriate clamp is advised. A cross-sectional view of such a clamp construction is shown in Fig 2. Refer to chapter 3.1 for ordering info.

2.4 Signal connections.
All signal connections are realized by using WAGO series 231 cage clamp connectors. A major advantage of these connectors is the fact that the connector can be fitted without the need for soldering. The connectors can be used with 0.08 mm2 (AWG 28) to 2.5 mm2 (AWG 12) wires, both stranded or massive.
The audio and RS-485 signal cable socket is supplied with the Intellivox. Also three different sized PVC inserts are supplied which can be inserted in the connector if small wire sizes are used (usually for the audio line input connection). The connector for the SPL/temperature measurement is supplied with the corresponding sensor. This sensor has to be ordered separately. Refer to chapter 3.1 for ordering information if the installation requires extra connectors.
The preferred cable types and the connector pin configuration is extensively discussed in chapters 3.2 and 3.3. All connectors are located in the Intellivox connector compartment which is accessible from the rear and front side of the column (except Intellivox-1b which is only accessible from the rear). A drawing of the connector block is shown in Fig 3. A figure similar to Fig 3 (right side) can be found at the rear side of the panel that covers the connector compartment.
