5.1 Mounting
With its dimensions (W x H x D) of 449 mm x 44 mm x 275 mm the RTS ISDN
2002 System can be operated as a table-top device or, be inserted into 19"
racks.
The dimensions given above are valid for the table-top version with no feet. If
the RTS ISDN 2002 System is to be inserted into a rack, it should be remem-
bered that the bending radius of the cables should always be greater than the
minimum allowed value.
If the RTS ISDN 2002 System is installed in a rack, it should also be ensured
that sufficient ventilation is provided. It is recommended that at least 1 cm
space is left next to the openings. As rule, the ambient temperature 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 failure
Operation of the unit outside the above limits invali-
dates the warranty.
The RTS ISDN 2002 System must therefore be oper-
ated within the specified limits.
5.2 Connection to the mains voltage
The integrated power supply unit of the RTS ISDN 2002 System can be oper-
ated with a voltage (mains) between 90 V and 253 V. The mains frequency
can vary between 50 Hz and 60 Hz. The power consumption is a maximum of
approx. 20 W.
After putting the unit into operation, the “POWER” LED should light up. An in-
ternal reset is then triggered. This is indicated by a blinking “ALARM” LED.
After approximately twenty seconds, the unit is operational and the red
"Alarm" LED should stop blinking.
5.3 Signalling LEDs
There are six LEDs for signalling on the RTS ISDN 2002 System
(see Figure 2):
•
Power: green
Lights up when system is powered.
•
Alarm: red
Lights up if a fault has occurred in the unit.
