Supply & Load Cable Connections - Philips Dynalite DBC1205 Installation Manual

supply & load cable connections
Supply Cables
The supply input terminals are located toward
the top of the enclosure and consist of Earth,
Neutral and 3 Phases, which will accept up to
2
10mm cables. The supply cables should have
a capacity of 20A per phase, to allow the
device to be loaded to its maximum capacity.
Load Cables
Load cables can be terminated on the 12-way
Load and neutral terminal strip (one for each
channel), and an Earth link located at the
centre of the enclosure. These connectors will
2
accept up to 6mm cables. It is important that
an individual output circuit is not overloaded.
Calculate the intended load, and ensure that it
is below the maximum capacity of an individual
channel, which is 5A. To ensure compliance
with interference standards, the load neutral
cables must be individually connected to the
neutral link terminals inside the cabinet. Never
use a common neutral at a remote location.
Load Control Cables
Load control cables can be terminated on the 2
x 12 way terminal strips located directly above
the load terminals. The left terminal block is
the output for 1-10V, or DSI if selected by
software setup. Note that most 1-10V HF
fluorescent ballast control wiring is polarity
conscious. The +terminal of the ballast
connects to the left terminal block, and the –
terminal connects to the right (common)
terminal block. DSI ballasts are not polarity
conscious.
Energising the Device
If it is necessary to energise load circuits
before any control cables are connected, it is
acceptable to replace the cover and energise
the device immediately, as the default factory
programming is to have all channels set to
100% output. If there is no output on any or all
channels, see the troubleshooting section
(page 10). This device should be de-energised
before terminating the control and data cables.
