INSTALLATION OF THE POWER SUPPLY FOR CV 2
The CV 2 has a 10 meter 4 wire shielded cable to connect to the power supply
The Connection between the CV 2 cable and the adapter cable can be made
with any standard connection terminal block (e.g. like the one that is used
inside the CV 2 connection box, see figure 5.2). The shield of the power supply
cable is connected to the base plate inside the CV 2.
Figure 5.2 Connection block inside the CV 2
The DC output from the power supply unit is marked with a red sleeve on
the + wire.
For activating the ventilator the blue wire has to be connected to the 0 Volt, the
red wire has to be connected to the + 12 Volt.
The heater also uses the common blue wire as 0 Volt and green/white as the
+ 12 Volt connection
When only the green or white is connected the heating power is 5 Watt.
When both green and white are connected the heating power is 10 Watt.
Because all resistors (R1 - R4) are mounted on a metal ring around the
ventilation shaft, the dissipated heat is equally spread over the opening.
Therefore it does not matter whether the green or white wire is used for 5-Watt
operation.
The need for heating strongly differs on local climatological circumstances.
Generally heating is advised during cold seasons when frost and dew can be
expected.
