3.1 Installing the cassette
– Ensure the head-end station is mounted so it will not be able to vibrate.
Avoid, for example, mounting the head-end station onto a lift shaft or any
other wall or floor construction that vibrates in a similar way.
– Before installing or changing a cassette unplug the power cable from the
mains power socket.
• Remove the fastening screws
1
of an unoccupied slot from the bracket of the
head-end station.
• Insert the cassette in this slot and push it into the housing.
• Align the cassette and apply slight pressure to connect it to the connections of
the board and the HF bus bar.
• Fasten the cassette with the
1
screws.
3.2 EMC regulations
To comply with the current EMC regulations, it is necessary to connect the
lines leading in and out of the head-end station using F terminals.
The attenuation of shielding of the connection lines must meet the require-
ments for “Class A”.
When mounting the cassette in a STR 19-8 head-end station which is in-
stalled in a 19” cabinet, make sure the connections leading in and out for
the 19” cabinet are made using F terminals.
