Supply Cables
The supply input terminals are located toward
the centre of the enclosure and consist of
Earth, Neutral and 3 Phases, which will accept
up to 16mm
2
cables. The supply cables should
have a capacity of 40A per phase, to allow the
device to be loaded to its maximum capacity.
Load Cables
Load cables can be terminated on the 2-way
Load terminal blocks (two for each channel), a
Neutral link and an Earth link located at the
centre of the enclosure. These connectors will
accept up to 10mm
2
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 10A. 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
4 way and 2 way terminal blocks located
directly next to the Load terminals. These
terminals are the outputs for 0 to +10V, DSI or
DALI if selected by software setup. Note that
most types of 1-10V HF fluorescent ballast
control wiring is polarity conscious. DSI
ballasts are not polarity conscious.
Emergency Lighting Connections
Connect Emergency Lighting circuit active to
the load side on the circuit breaker for the
relevant channel, as indicated by the labels
next to the circuit breakers. Do not remove
any cables that may already be terminated at
this location.
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 8). This device should be de-energised
before terminating the control and data cables.
