6.1
Mounting
With dimensions (W × H × D) of 439 mm × 44.5 mm (1 U) × 395 mm, the
MAGIC ETI Decoder can be used as a table-top unit or, equipped with mount-
ing brackets, can be installed in ETSI or 19-inch racks.
The dimensions given above are valid for the table-top version with neither
mounting brackets nor feet. If the MAGIC system is to be inserted into a rack,
it should be remembered that the bending radius of the cables should always
be greater than the minimum allowed value.
If the MAGIC system is installed in a rack, it should also be ensured that suf-
ficient ventilation is provided. It is recommended that at least 3 cm space is
left. As a rule, the ambient temperature should not lie outside the range +5 ° C
to +40 ° C. These limits are of particular importance if the MAGIC system is in-
serted in a rack.
During operation, the humidity must lie between 5% and 85%.
Notice
Incorrect ambient temperature and humidity can lead to equipment
failure
!
Operation of the unit outside the above limits invalidates the warranty.
The MAGIC system must therefore be operated within the specified limits.
6.2
Connection to the mains voltage
The MAGIC system can be operated with a voltage (mains) between 90 and
253 V without the need for switching. The mains frequency can vary between
45 Hz and 65 Hz. The power consumption is a maximum of approx. 35 W. The
housing must be earthed (grounded) in accordance with local regulations.
This earthing is usually realised via the protective conductor of the mains ca-
ble. If the mains cable does not have a protective conductor, however, the de-
vice must be earthed via the earthing bolt at the rear of the unit.
WarnIng
Dangerous voltages in the event of improper earthing!
If there is improper earthing, dangerously high voltages can be present on the
unit housing in the event of a fault.
Do not use extension cables without protective earth contacts!
In case of doubt, use additional earthing!
After the unit is switched on, the green "POWER" LED should light up. An in-
ternal reset is then triggered. This is indicated by a blinking "ALARM" LED. Af-
ter approximately twenty seconds, the unit is operational.
