10.4.4 Electrical installation

Cable cross-section

The connection cables for the power supply must have a cross-section of at least

0.75 mm

(approx. 20 AWG).

See also Chapter 5.4.2 Supply voltage, Page 5-16.

Power consumption

The power consumption depends on the variant:

• Line scanner with heater: typically 75 W and max. 90 W

• Line scanner with oscillating mirror and heater: typically 75 W and max. 100 W

These values apply to operation without the switching outputs connected.

CDB420 or CDM490 Connection Modules

The CDB420 or CDM490 Connection Modules are suitable to power the CLV490 with hea-

ter. An external power supply pack with a higher power output must be used to provide the

required voltage of 24 V DC +20%/–10%. The incomming/outgoing cables must be pro-

tected by corresponding fuses. The optional CMP490 Power Supply Module is not suitable

for CLVs with heater.

See Chapter 3.1.3 System requirements for stand-alone configuration, Page 3-2.

For connecting the CLV490 with heater to the CDB420 or CDM490 see also the "CDB420

Connection Module" Operating Instructions (order no. 8010001, German/English) respec-

tively the "CDM490 Connection Module" Operating Instructions (order no. 8010005, Ger-

man/English).

10.4.5 Outdoor applications

If the CLV490 with integrated heater is used outdoors, it should be installed in a protective

housing to prevent the front window from being damaged by rain, snow, or dust. The housing

also acts as a wind protector.
