3.5 D2O INTERFACE CABLE ATTACHMENT
The D2O is capable of being mounted in several ways. In all mounting
scenarios it is recommended that the supplied 1.5 meter 8-Pin M12 Interface
Cable is threaded through the mounting device (e.g. a post), emerging only at
the point of connection to a device or junction box. This is to decrease the risk
of damage to the 8-Pin M12 Interface Cable from sources such as:
• Bird, livestock or other animal damage or abrasion
• Falling branches or foliage
• Premature cable deterioration from ultraviolet light and weathering
• Snag risks
As such it is important to prepare the mounting device and cable before
installing the D2O.
If applicable, an appropriately sized hole should be drilled where the cable
will exit the mounting device and the cable threaded through the post and
hole prior to attaching the D2O. Ensure the hole is clean, de-burred and will
not damage the cable. Consider the use of a rubber grommet on the hole
edge to increase protection.
The 8-Pin M12 Interface Cable should then be attached and fastened to
the D2O unit via the 8-Pin M12 Connector, ready for final mounting and
commissioning.
3.6 POST MOUNTING
The D2O supports direct installation to a cylindrical post. The mounting
socket on the D2O can accommodate a post with:
• Outer diameter 32mm - 34.5mm
• Internal diameter >26mm
The preferred solution for direct mounting of the D2O is the use of a Nominal
Pipe Size (NPS) steel post with a Diameter Nominal (DN) 25mm or 1 Inch,
as specified in the Australian/New Zealand standard AS/NZS1163 or the
American Standard ASTM A53M.
25mm (DN) NPS is specified as having an outside diameter of 33.4 - 34mm and
is commonly available in hardware stores and from steel suppliers, often sold
as fence posts.
Suitably secured galvanised or stainless steel post should be used to ensure
weather resistance and durability. Providing a path for any water to drain from
within the post will reduce corrosion potential and extend the installation life.
As well as ensuring a suitable height for transmission capabilities, as per the
Site Selection section, the height of the post should also correspond to the
risk of damage or interference to the D2O. For example if used in an area with
livestock the device should be higher than the livestock could reach. If prone
to vandalism the D2O should be high enough to deter interference and may
require additional protection mechanisms.
