5.4.3 Non-SICK Power supply unit/connections without the Connection Module
Power output
If an non-Sick Power supply unit is used, it must be capable of providing the following voltage
and power values:
• For CLV490 without heater: 18 to 30 V DC, min. 20 W continuous power output
• For CLV490 with heater: 24 V DC +20 %/–10 %, min. 100 W
The non-Sick Power supply unit must provide the functional extra-low voltage in accordance
with IEC 364-4-41.
The output circuit must be reliably electrically isolated from the input circuit. To do so,
use a safety isolating transformer pursuant to IEC 742.
Wire cross-section
The wire cross-section for the power supply (Pin 1/Pin 5) should be at least 0.15 mm
2
(approx. 26 AWG) or 0.75 mm
2
(approx. 20 AWG) for CLV490 with heater, with a max.
length of 10 m (32.8 ft).
