Ac Power Shunts - Cisco GS7000 Installation And Operation Manual

Preface
Maximum current through the node is 15 Amps. A suitable current limiter is to be provided during end
installation or service provider Ferro resonant power source shall have suitable current limiter.
Shock Hazard - Housing/Enclosure of the unit must be reliably bonded to protective earth/ground conductor
prior to connecting the unit to a power source.
Do not touch internal conductor of F/COAX connector or coax cable while the node is energized and
disconnect power before removing cover because 90 V a.c. can be accessible.
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).
In Norway, due to regulation for installations of cable distribution systems, and in Sweden, a galvanic
Note
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 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.

AC Power Shunts

AC power shunts may be provided with this equipment.
Important
The power shunts (where provided) must be removed before installing modules into a powered housing.
With the shunts removed, power surge to the components and RF-connectors is reduced.
