5.4.1
(A11:2008)
(A11:2008)
Norway and Sweden
To the end of 5.4.1 (after the compliance statement)
the following is added:
The screen of the cable distribution system is
normally not earthed at the entrance of the building
and there is normally no equipotential bonding
system within the building. Therefore the protective
earthing of the building installation need to be
isolated from the screen of a cable distribution
system.
It is however accepted to provide the insulation
external to the equipment by an adapter or an
interconnection cable with galvanic isolator, which
may be provided by e.g. a retailer.
The user manual shall then have the following or
similar information in Norwegian and Swedish
language respectively, depending on in what
country the equipment is intended to be used in:
“Equipment connected to the protective earthing of
the building installation through the mains
connection or through other equipment with a
connection to protective earthing – and to a cable
distribution system using coaxial cable, may in
some circumstances create a fire hazard.
Connection to a cable distribution system has
therefore to be provided through a device providing
electrical isolation below a certain frequency range
(galvanic isolator, see EN 60728-11)”
NOTE In Norway, due to regulation for installations
of cable distribution systems, and in Sweden, a
galvanic isolator shall provide electrical insulation
below 5 MHz. The insulation shall withstand a
dielectric strength of 1,5 kV r.m.s., 50 Hz or 60 Hz,
for 1 min.
Translation to Norwegian (the Swedish text will also
be accepted in Norway):
“Utstyr som er koplet til beskyttelsesjord via
nettplugg og/eller via annet jordtilkoplet utstyr – og
er tilkoplet et kabel-TV nett, kan forårsake
brannfare. For å unngå dette skal det ved tilkopling
av utstyret til kabel-TV nettet installeres en
galvanisk isolator mellom utstyret og kabel-TV
nettet.”
Translation to Swedish:
”Utrustning som är kopplad till skyddsjord via jordat
vägguttag och/eller via annan utrustning och
samtidigt är kopplad till kabel-TV nät kan i vissa fall
medföra risk för brand.
Főr att undvika detta skall vid anslutning av
utrustningen till kabel-TV nät galvanisk isolator
finnas mellan utrustningen och kabel-TV nätet.”
