If The Wall Mounting Option Is Chosen - Acom Owner's Manual

Do not commence tuner installation if you don't have a secure lightning protection
grounding system as per Section
.
outdoor
Do not use grounding systems that are nоt built to regulations - this may lead to fire, gas
explosion, other incidents or death, including that of other persons. Never use the tuner,
unless it is properly grounded!
At first, lay out the cables along the route to the radio station and antennas, and protect them from
mechanical damage, in case they move in the wind, snow or ice. When the end of the cable is inserted in the
foundation of the building, take precautions to seal against wetting the connecting terminals, main grounding
plate of the building (see Point
sufficient U-shaped slack before cable insertion to facilitate water drip off.
At the selected location install an appropriate set of installation accessories (ACOM 04-WM for walls or ACOM
04-MM for masts), as described hereafter. Do not install the protection cover at this point.
The tuner should be mounted strictly horizontally, with the connectors facing downwards and at a height of
no less than 1 m above base level (ground or roof).
The installation height above the base is essential in order to install cables with a sufficient U-shaped slack
under the tuner bottom level, so that any rain, dew and other precipitation or sprays reflected from base will
not wet the tuner and will safely drip off.
Also, in the case of heavy snowfall, the snow will not reach the tuner connectors.

The whole assembly (Pos. 1 & 2) is then secured to a wall with 6 bolts (Pos. 3) with the weather protective
cover facing up. Although the weather protective cover (Pos. 1) provides the necessary shielding from the
elements, whenever it's possible, the tuner should be mounted under a shed. This way maximum protection
and minimum material wear both from water and sunlight and heat will be provided, extending the tuner's
operational lifespan. When installing the system outdoors always select a location, free from any possible
loose cables or other objects that might fall on or hit the tuner assembly.
