3.3 MINIMUM CLEARANCE
Irrespective of the mounting type or scenario, the D2O must have a minimum
clearance to the nearest object to avoid Radio Frequency (RF) interference
and adverse Antenna influence.
With the exception of the mounting device itself (post, mast etc.), there should
be no other surfaces or objects within 150mm below the base of the D2O unit
and 500mm radially from the centre of the unit as per the diagram.

As a first step the
Antenna
must be installed on the D2O unit before it will
function.
Before screwing the
Antenna
to the D2O locate the
M5 Serrated Tooth Washer
and slip it over the
Antenna Base
. The
Antenna
is then attached by screwing
it on the exposed
Antenna Base
thread on the top of the D2O unit. It should
be tightened to an extra one third of a turn after the Antenna contacts the
M5 Serrated Tooth Washer
. This ensures the toothed washer sufficiently
engages with the plastic of the D2O and the Stainless Steel of the
Antenna
to
provide an anti-rotation, locking function. Do not over-tighten the Antenna as
irreparable damage may occur.

IMPORTANT NOTE:
Extra care should be taken when handling the D2O once the
Antenna has been attached. Eye protection is recommended
to avoid accidental eye contact with the Antenna tip.
3.4 PRE-ASSEMBLY
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.
