Installation Instructions
8.0 C-Bus System Clock
The C-Touch Colour incorporates a software selectable C-Bus System Clock
used for synchronising data communication on a C-Bus network. Since a
maximum of three enabled System Clock units should exist on a network,
the System Clock on the C-Touch Colour is disabled by default.
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 Network window of a
C-Bus Toolkit project provides a summary of a C-Bus network according to
the units added to the Database. This can be helpful in determining the
power supply requirements of a particular network.
10.0 Power Surges
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
Important points when megger testing an electrical installation:
• Only megger test when mains cabling is disconnected from C-Bus
output units.
• Do not megger test the C-Bus cable.
