5.4.3
Non-SICK power supply unit/connections without the SICK connection
module
If a non-SICK power supply unit is used instead of the CDB 420 or CDM 420, it must provide
a functional extra-low voltage in accordance with the standard IEC 364-4-41 and a
continuous power output of at least 12 W.
The output circuit must be reliably electrically isolated from the input circuit. Do do so,
use a safety isolating transformer pursuant to IEC 742.
The minimum wire cross-section for the power supply (pin 1/pin 5) must be at least
0.15 mm
2
(approx. 26 AWG).

Use the cable no. 6 010 137 with 15-pin D-Sub HD cable socket and open end to
connect the ICR.
The color assignment of the wires is shown in
.
Note
The wiring color assignment shown above only applies for the upper cable, not for the
connection cable with the cable plug which runs to the ICR housing.
