1.5.2.5 At the place of entering the building,
before going further to the radio station, the feedline between the amplifier and tuner
input should be equipped with a pulse overvoltage limiter (surge arrester), the ground-
ing terminal of which should be connected through a low-impedance connection to
the main grounding plate of the building (Appx.1-8).
1.5.3 Electric Safety Precautions
The electronics inside the tuner operate under high di-
rect-current voltage up to 200V, which is fatal! Never allow
anyone, especially children, to insert any object into box
holes – this may cause electric shock. Disconnect all ca-
bles from the tuner and every time wait at least 1 minute
before opening it!
RF voltage at antenna feedpoint and elements may exceed
several thousand volts! Never touch the antenna or an-
tenna isolators during transmission and tuning – this may
cause deep RF burns as well as indirect traumas, such as
falling!
1.5.4 General Safety Precautions
Do not undertake any repair or alteration in the design or
software of the tuner by yourself, as this may threaten your
or someone else's health and life, or damage the tuner or
connected equipment, which is not covered by the warran-
ty.
To prevent damages not covered by the warranty, read
carefully Section 2, TUNER INSTALLATION, in this Oper-
ating Manual. Should you have any doubts related to in-
stallation, your safety during operation or tuner reliability,
please contact your local ACOM dealer first. See S. 1.2 for
ACOM contact information.
2. TUNER INSTALLATION
The tuner can be installed at a fixed site (in a room), under a shelter or outdoors – with
a special set of installation accessories for desks, walls or masts.
