Mains Powered Units
As a minimum, the power connection cable should be 3 core over sleeved,
with minimum 0.5mm insulation and rated at 300 V. Cables should have
Live (L), Neutral (N) and Earth [Ground] (E) conductors.
Ensure suitably rated power supply cables and glands are used to ensure that
electrical safety is maintained. Connect each of the Live (L), Neutral (N) and
Earth [Ground] (E) conductors to the similarly marked terminals (L, N, E) on
the Power In connector shown above.
24 V DC Units
The cable should be rated at a minimum of 10 A at 50 V DC with minimum
0.5mm insulation. Connect the +24 V conductor to the terminal
and the 0 V conductor to the terminal marked -.
Before applying power, perform a continuity test to ensure that the power supply cable
and product are effectively connected to the protective earth. A protective earth terminal
is mounted internally and the Earth wire connected to it should never be disconnected.
Do not remove or exchange any of the cables, electrical components or any other parts
supplied with this product. Doing so will invalidate all warranties.
If installing rigid conduit, a stopping fitting must be installed within 46cm (18") of the
enclosure.
There are no additional or special electrical safety requirements other than those
referred to in this manual.
