accordance to the US National Electrical Code, Articles 110-16, 110-17 and
110-18, and the Canadian Electrical Code, Section 12.
Overcurrent Protection: A readily accessible listed branch circuit
overcurrent protective device, rated 15 A, must be incorporated in the
building wiring.
Grounded Supply System: The equipment shall be connected to a properly
grounded supply system. All equipment in the immediate vicinity shall be
grounded the same way, and shall not be grounded elsewhere.
Local Supply System: The DC supply system is to be local, i.e. within the same
premises as the equipment.
Disconnect Device: A disconnect device is not allowed in the grounded circuit
between the DC supply source and the frame/grounded circuit connection.
Special Requirements for Norway and Sweden:
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).
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.
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
medfőra risk főr brand. Főr att undvika detta skall vid anslutning av
utrustningen till kabel-TV nät galvanisk isolator finnas mellan utrustningen
och kabel-TV nätet.
