Electrical connection
5.4.3
Non-SICK power pack/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 4 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) is 0.15 mm
2
(approx.
26 AWG).
Use the cable no. 6 010 137 with 15-pin D Sub HD socket and open wire ends to
connect the CLV. The color assignment of the wires is shown in
Note
The CLV 42x is UL certificated when a class 2 power supply according to UL 1310 is used.
