×
220 mm the RTS SIP-
ISDN System can be used either as desktop device or mounted in 19 inch racks. Corre-
sponding 19“ mounting brackets are included in delivery. Optionally, a mounting kit to
install two
RTS SIP-ISDN next to each other is available.
When mounting the unit please keep in mind that the bending radius of the cables is al-
ways greater than the minimum allowed value.
When the RTS SIP-ISDN Audio Codec is installed, please make sure that there is suffi-
cient ventilation: It is recommended to keep a spacing of ca. 3 cm from the openings. In
general, the ambient temperature of the system should be within the range of +5
°
C and
+45
°
C. These thresholds are especially to observe if the system is inserted in a rack. The
system works without ventilation.
During operation air humidity must range between 5% and 85%.
3.2 Connection to the mains voltage
The system can be operated with mains voltages in the range from 90 V to 253 V via the
external power supply included in delivery. The line frequency can vary from 45 Hz to
65 Hz. The maximum power consumption is 15W. The rack must be earthed according
to the VDE Regulations. The earthing can be carried out via the earthing screw on the
back side of the unit.
The unit does not have a circuit closer and a circuit breaker. After plugging in the external
power supply the system boots within a few seconds. In standby mode the RTS logo is
shown on the display.
TIP
The system temperature can be indicated on the display (

ATTENTION Incorrect ambient temperature and humidity can cause functional deficiencies
Operation outside the threshold values indicated above leads to a loss of warranty
claim.
