9.0 C-Bus Power Requirements
The C-Touch Colour draws 20 mA from the C-Bus network. Adequate
C-Bus power supply units must be installed to support connected devices.
If in doubt, refer to the C-Bus Training Manual. The C-Bus Calculator
software is useful in determining power supply requirements. Note that
factors such as even power supply distribution and cable length have an
impact on the actual power requirements.
10.0 Power Surges and Short Circuit Conditions
The mains voltage to the Power Supply must be limited to the range
specified. The Power Supply unit incorporates transient protection
circuitry, however external power surge protection devices should be used
to enhance system immunity to power surges. It is strongly recommended
that over voltage equipment such as the Clipsal 970 is installed at the
switchboard
11.0 Megger Testing
Megger testing of a mains electrical installation that has C-Bus units
connected, will not damage the units. Since C-Bus units contain electronic
components, this should be taken into account when interpreting megger
readings.
Never perform megger testing on the pink C-Bus data cabling or terminals,
as this may degrade the performance of the network.
