When operating the device via the optional SICK CDB650-204 or CDM420-0006 connection module and using a SICK connecting cable.
When operating the device below 0 °C and using a cold-resistant connecting cable from SICK.
2
When operating the device without a SICK connection module and using a SICK connecting cable. When operating the device below 0 °C
and using the cold-resistant connecting cable from SICK, part no. 6048319 (2 x 2.5 mm
2
, 10 m).
•
The power source must be able to deliver at least 26 W of power or at least 1.5 A
at 18 V DC.
•
The voltage supply via a power supply unit must be capable of bridging a brief
power failure of 20 ms.
•
In the case of connection via the optional connection module CDB/CDM: addition‐
ally required output power 0.5 W when using the optional parameter cloning mod‐
ule CMC600 in the connection module.
Protecting the supply cables
To ensure protection against short-circuits and overload in the customer-supplied
cables, the wire cross-sections used must be selected and protected in accordance
with national regulations.
The following standards must be observed in Germany:
•
DIN VDE 0100 (part 430)
•
DIN VDE 0298 (part 4) and/or DIN VDE 0891 (part 1)
Wiring without SICK connection module
For a supply voltage between 18 V and 30 V DC, protect the device with a separate 2 A
slow-blow fuse.
For a supply voltage between 12 V and 30 V DC and when operating the device with the
SICK supply cable part no. 6048319 (2 x 2.5
mm
2
, length 10 m), protect the device
with a separate 2.5 A slow-blow fuse.
b
Install the fuse in the supply circuit at the start of the supply cable.
