Supply Cables
The supply input terminals are located toward
the top left of the enclosure and consists of
Neutral, Line, and an Earth link located on
the chassis, all of which will accept up to
4mm
2
cables. The supply cables should
have a capacity of at least 0.5A. The supply
normally feeds the control electronics only
and does not feed the relay outputs unless
additional wiring is connected.
Load Cables
Load cables can be terminated on the 24 way
Load terminal strip, C (common), NC
(normally closed) and NO (normally open) for
each Channel. These connectors will accept
up to 2.5mm
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 resistive.
Derate for reactive loads. When connecting
ELV or SELV cables to the relay terminals
ensure that proper segregation is maintained
between them and mains cables.
Control Input Cables
There are 8 control inputs that terminate on a
10 way terminal strip. They are configurable
to Dry Contact and 0-10V Analogue. These
terminals are SELV (safety extra low voltage)
and any cables connected to them should be
segregated from mains cables.
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 9). The device should be de-energised
before terminating the control and data
cables.
