Installing the Monopole®
The Monopole® is installed1 into
its working appliance in the following manner:
Disclaimer: These instructions are advisory only.
To install your product consult a qualified professional.
No liability is accepted for any person following these instructions.
These instructions are to assist in the installation of:
M11; M13 and M14 Monopoles only.
The M16 uses the same hole size and spacing but does not have the
internal junction assembly as the other three.
M24 installation is custom to the appliance it is being installed
and determined by the end user but the following instructions are helpful.
( With the appliance unplugged from all sources of electrical power
and all power leads and interconnect leads and similar all disconnected
from the appliance ).
The Shoulder Washer assembly ( Comprising the coloured Threaded
Shoulder washer its Slip ring and locking nut ) is the point where the
Monopole® is installed into its working appliance.
With all the bolts removed from the pole piece and only the Threaded
Shoulder Washer attached; the fitting procedure is ready to begin. The
Threaded Shoulder Washer has a nose 20mm in diameter. If the appliance
does not have a 20mm hole into which to insert the nose then a chassis
punch should be used to cut the required diameter hole. With the insertion
hole cut the Monopole®, with just the Threaded Shoulder Washer attached,
is inserted into the appliance; junction end first, with the junction bolt
The slip ring is then slid over the junction end of the Monopole®
and located over the nose protrusion of the Threaded Shoulder Washer inside
the appliance and then the first locking nut tightens the slip ring over
the Threaded Shoulder Washers’ nose against the mounting hole; thus securing
the Monopole® firmly into the chassis of its working appliance. The
second locking nut is then tightened directly behind the first and this
further minimizes the prospect of the Monopole® coming loose during
its life on the appliance.
The wire connecting the Monopole® to the internals of its working
appliance can be connected into the junction pipe either by:
1: Threaded through the junction pipe in a figure of ‘8' . The Junction
bolt should then have a small drop of Koppercote anti-seize compound applied
at its mid length section closer to its bolt head than its nose end and
then screwed firmly into place. Ensure that the body of the figure of ‘8'
of the cable in the junction pipe is aligned with the centre of the junction
bolt as it is secured into place.
2: Placed onto the junction face at the bottom of the junction cylinder
and then tightened into place. Coiling the wire prior to fastening is also
recommended. To tighten the Junction Bolt: tighten the Junction Bolt with
the fingers only; after, use a 14mm ( 9/16" ) spanner and tighten for a
1/32ND turn only. Do not exceed 6Nm in torque. A copper bolt once firmly
secured will not tend to ‘drift’. Copper bolts are easily stripped and
extreme care should be taken when tightening. If in doubt use a torque
Re-tighten the junction bolt at least once within 24hrs after initial
installation. This may not be all that necessary as there have not been
any reported instances of the junction bolt ever coming loose. M11MkI Monopoles®
have been in service in several appliances since June 1994 and there has
been no evidence of slackening of the tension on any of these. In fact
on inspection it was noted that it was more difficult to loosen the junction
bolt with time than was originally perceived.
Also, the appliance wire fastened into the Monopole® did not
show any signs of work fatigue, breakage or wear. In fact the firm clasping
of the bare wire into the Monopole® body inhibited oxidation of the
copper at the pressure interfaces; so much so as to appear as if no oxidation
had taken place at all, even over the 14 months that the wire was ‘exposed’
to its working environment/appliance.
On none of the installations has any thread anti-seize or locking
compound been used. The compounds suggested are mentioned in order that
any installer wishing to placate their fear of the junction bolt coming
loose can do so by utilizing these compounds.
If you still have fears of the junction bolt loosening than a small
amount of solder can always be applied to the bolt through the junction
pipe at the bolt head end of the junction pipe.
With the internal appliance wire attached and the Monopole®
firmly located into the chassis of its working appliance then the appliance
cover can now be closed and the external bolts and/or nuts re-fitted to
the Monopole® pole piece.
The removal of operational bolts on the M13 does not apply as those
working parts on the M13 external to the working appliance are not removable.
However the internal parts are the same as per the M11 and M14.
Where the Monopoles® are supplied on a template then the template
needs to be fitted to its working appliance and then the steps D - G need
to be followed to install the internal wires of the working appliance into
the Monopoles® located on the template.
If in doubt as to how to wire your Monopoles®) contact a suitably
qualified electrical technician ( state certified )
IF YOU ARE NOT A QUALIFIED ELECTRICIAN
OR ELECTRICAL ENGINEER DO NOT DO THIS.
TAKE YOUR APPLIANCE TO AN AUTHORISED
TECHNICIAN AND HAVE THEM INSTALL YOUR TOMCATSTM
In all wiring process ensure that the polarities match:
L: Oxidation considerations.
Black for negative
Red for positive.
Copper readily oxidizes in the presence of oxygen and the air that
we breathe contains oxygen. The M9 and M11 Monopoles® in use in my
appliances have had their fitted wires in for over 3-4 years. Regular inspection
has not revealed any presence of oxidation. This principally due to the
pressure of the junction bolt in securing the appliance wire firmly into
the Monopole® body.
Trusting that all the above information will assist you in appreciating
the meticulous work and care that has gone into the design and fabrication
of the above componentry
BUT if the process of oxidation still worries then the following
precautions can be taken: Coating the appliance wire with KopperKote (
or similar electrically conductive anti-seize compound prior to securing
the wire into the Monopole® body with the Junction Bolt.
This does has one additional advantage. By coating the wire with
an electrically conductive paste such as KopperKote or ROCOL
J166 the pressure of the Junction Bolt will hold the wire into the
Monopole® Pole piece. The paste surrounding that part of the wire not
in contact with the pole face will still be actively conducting the electrical
signal in a minimized oxidation environment.
