Communication equipment,
installation
IMPORTANT!
All installation of optional electronic communication equip-
ment must be performed by trained professionals and in
accordance with Volvo Construction Equipment instructions
applicable to the specified machine.
Protection from electromagnetic interfer-
ence
This machine has been tested in accordance with EU directive 89/
336EEC governing electromagnetic interference. It is therefore
very important that all non-approved electronic accessories, such
as communication equipment, should be tested before installation
and use, since they can cause interference to the electronic sys-
tems of the machine.
Mobile telephones
To obtain the best functionality, mobile telephones should be per-
manently installed in the electrical system of the excavator, with a
permanently antenna fixed on the cab, installed as advised by the
manufacturer. If a portable mobile telephone is used, note that this
can constantly transmit information to its base station, even when
the telephone is not used. For this reason, it should not be located
right beside electronic equipment in the machine, such as directly
on a control panel etc.
Guidelines
The following guidelines must be followed during installation:
– The antenna placement must be chosen to give good adapta-
tion to the surroundings.
– The antenna cable must be of the coaxial type. Be careful to
ensure that the cable is undamaged, that the sheath and braid
are not split at the ends, the braid covers the connector ferrules
and has good galvanic contact with them.
– The mating surface between the antenna mounting bracket
and the bodywork must have clean metal surfaces, with all dirt
and oxide removed. Protect the mating surfaces against corro-
sion after installation to maintain good galvanic contact.
– Remember to separate interfering and interfered cables physi-
cally. Interfering cables consist of the communication equip-
ment's supply cables and antenna cable. Interfered cables are
those which are connected to electronic devices in the ma-
chine.
