Electrical installation
There is effective suppression of ground loops even at ground potential differentials of up
to 60 V RMS / 80 V DC maximum. As result, equalizing currents can no longer flow via the
cable shields and metal housing.
Important The power supply for the TiM5xx and the connected peripheral devices must also guarantee
the required level of insulation.
Under certain circumstances, a tangible potential can develop between the insulated metal
housings and the local ground potential.

Varning och atjarder
Utrustning som ar kopplad till skyddsjord via jordat vagguttag och/eller via annan utrustning
och samtidigt ar kopplad till kabel-TV nat kan i vissa fall medfora risk for brand.
For att undvika detta skall vid anslutning av utrustningen till kabel-TV nat galvanisk iso-
lator finnas mellan utrustningen och kabel-TV natet.
Advarsel og tiltaker
Utstyr som er koplet til beskyttelsesjord via nettplugg og/eller via annet jordtilkoplet utstyr
- og er tilkoplet et kabel - TV nett, kan forarsake brannfare.
For a unnga dette skal det ved tilkopling av utstyret til kabel-TV nettet installeres en gal-
vanisk isolator mellom utstyret og kabel-TV nettet.
Corresponding English translation
Devices which are connected to the electrical system PE of the building via a mains connec-
tion or other devices with a connection to the PE, and which are connected to a cable distri-
bution system with coaxial cables, can under certain circumstances cause a risk of fire.
Connections to a cable distribution system must therefore be made such that electrical
insulation is offered below a certain frequency range (galvanic separating link).
