Acom 04AT Operating Manual page 15

Do not commence tuner installation if you don't have a se-
cure lightning protection grounding system as per S. 1.5.2.
Do not use grounding systems that aren't built to reg-
ulations – this may lead to fire, gas explosion, other inci-
dents 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 pro-
tect 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
(appx.1-8) or other connections thereof. As a minimum, leave a sufficient U-shaped
slack before cable insertion to facilitate water dripoff.
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 down-
wards and at a height of no less than 1m above base level (ground or roof).
The installation height above the base is essential in order to install cables with a suf-
ficient 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 dripoff.
Also, in the case of heavy snowfall, the snow will not reach the tuner connectors.
2.4.1 If the wall mounting option is chosen – Fig.2-4
The protective cover (1) is removed by unscrewing the five bolts (2). The five cover
holding brackets (7) are left in place, attached to the tuner body. Using the provided in
the mounting kit four flat-head bolts (5), the wall bracket (4) is secured to the tuner body
(3) and then the protective cover (1) is secured back in place with the five bolts (2).
