4.6.2 Connecting the Supply Voltage
The CLV61x requires a power supply unit with the following characteristics:
Supply voltage DC 10 V to 30 V (stabilized safety extra-low voltage [SELV]).
The power supply unit must satisfy the requirements of SELV in accordance with the
currently applicable EN 60950-1.
The power source must be able to provide at least 3.5 W output or max. 700 mA.
Additional 0.5 W output power when using the optional CMC600 parameter cloning
module in the CDB620-001 or CDM420-0001 connection module.
Protection of Supply Cables
To ensure protection against short-circuits/overload in the supply cables from the custom-
er's power system, the lead cross sections used have to be selected and protected
according to the national standards.
The supply voltage is fed via the connection module, for to do so please see:
The connection modules have each one fuse (0.8 A slow blow) in the electrical circuit down-
stream of the S1 switch.
Wiring without SICK Connection Module
The CLV61x must be protected using a separate fuse of max. 2 A slow blow, in the supplying
circuit at the start of the supply cable.
