Mounting

With its dimensions (W × H × D) of 439 mm × 44,5 mm (1 HE) × 300 mm, the
MAGIC ISDN Telephone Hybrid System can be operated as a table-top device
or can be mounted in 19'' racks. Additionally, mounting brackets are pro-
vided for 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 ensured
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 par-
ticular importance if the system is inserted in a rack.
During operation, the humidity must lie between 5% and 85%.
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 mains 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 approx. 30W. In accordance with safety regulations, the
housing must be earthed (grounded). This earthing is normally realised via
the protective earth (or ground) conductor of the mains cable. If the mains ca-
ble does not have a protective conductor, however, the device must be
earthed via its earthing bolt.
Dangerous voltage in case of inadequate 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 cables without an earthing conductor!
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. After approx. 45 seconds, the system is ready for
operation, when the red LED ALARM stops blinking.
