5 Electrical installation
5.1 Installation sequence
• Connect the CLV490 to a CDB420 or CDM490 Connection Module, or using a custom-
er-specific wiring configuration
• Connect the data and function interfaces of the CLV490 in the module
• Connect the PC to the Connection Module (at the auxiliary interface on the CLV490)
• Connect the power supply to the Connection Module
5.1.1 SICK Connection Modules (overview)
For technical data on the modules see Chapter 10.13.3 Accessories: Hoods, Page 10-75.
5.2 Electrical connections and cables
The electrical connections on the CLV490 consist of two 15-pin D Sub HD connections on
the housing, one plug, and one socket.
These connections are used to route the following interfaces:
• Three data serial interfaces (host interface, CAN interface 1 and 2, auxiliary interface)
• Six switching inputs (external reading pulse and multifunctional inputs)
• Four switching outputs (for result status function, for connecting to a PLC for example)
• Power supply
