Electrical installation

5.4.3 Non-SICK Power supply unit/connections without the Connection Module

Power output

If an non-Sick Power supply unit is used instead of the AMS 60, it must be capable of

providing the following voltage and power values:

•

For CLV without heater: 18 ... 30 V DC, min. 20 W continuous power output

•

For CLV with heater: 24 V DC +20 %/–10 %, min. 100 W

The non-Sick Power supply unit must comply with IEC 742 (functional extra-low voltage).

The output circuit must be reliably electrically isolated from the input circuit pursuant

to IEC 742 by means of double insulation and a safety isolating transformer.

Wire cross-section

The wire cross-section for the power supply (Pin 1/Pin 5) should be at least 0.15 mm

, or

0.75 mm

for CLVs with heater, with a max. length of 10 m.

a) Connecting the CLV without a connector cover/external parameter memory

The two cables no. 2 020 303 and no. 2 020 264 with open cable end on one side are

required to connect the CLV. The wire color assignments are shown in

Table 5-10

and

Table5-11, Page5-10.

The cables must not be extended for CLVs with heater.
