Mounting

With its dimensions (W × H × D) of 439 mm × 44,5 mm (1 HE) × 300 mm the
MAGIC ISDN Telephone Hybrid can be operated as a table-top device or be
inserted into 19'' racks. Additionally, mounting brackets are provided for the
installation into an ETSI rack.
During the installation care should be taken to ensure that the bending radius
of the cables is always greater than the minimum allowed value.
If the MAGIC ISDN Telephone Hybrid is installed in a rack, it should be en-
sured that sufficient ventilation is provided. It is recommended that approx.
3 cm clearance is left next to the openings. As a rule, the ambient temperature
of the system should not lie outside the range +5 ° C to +40 ° C. These limits are
of particular importance if the system is inserted in a rack.
During operation, the humidity must lie between 5% and 85%.
NOTICE Incorrect ambient temperature and humidity can lead to equipment fail-
ure.
Operation of the unit outside the above limits invalidates the warranty.
!
The operation of the system must therefore lie within the specified limits.

Connection to the mains supply

The system can be operated with a system voltage between 90 V and 253 V
and a mains frequency between 45 Hz and 65 Hz. The power consumption
has a maximum value of approximately 35 W. In accordance with safety reg-
ulations, the housing must be earthed (grounded). This earthing is usually re-
alised via the protective (earth or ground) conductor of the mains cable. If the
mains cable does not have a protective conductor, however, the device must
be earthed via the earthing bolt.
WARNING Dangerous voltage in case of wrong earthing!
If the earthing is defective or lacking, hazardous voltages can be present on
the housing in the event of a fault.
Do not use extension cable without an earthing contact!
In case of doubt provide additional earthing!
After switching the system on, the green POWER LED should light up. An in-
ternal reset is then triggered. When the ALARM LED stops blinking the sys-
tem is ready for operation (approx. 45 seconds).
