5.4 Preparations for electrical installation
5.4.1 Requirements for the host interface
The host interface of the CLV can be operated as an RS 422/485 or an RS 232 interface.
Table 5-7 shows the recommended maximum cable lengths as a function of the selected
data transfer rate.
¾ To prevent interference, do not lay the cables parallel with power supply and motor
cables over long distances, e. g. in cable ducts.
5.4.2 Supply voltage
The CLV requires a power supply of 18 to 30 V DC for operation without a heater and
24
V DC +20 %/–10 % for operation with a heater (each functional extra-low voltage in
accordance with IEC 364-4-41). The functional extra-low voltage can be generated by using
a safety isloating transformer pursuant to IEC 742.
The power consumption of the individual types is as follows:
Power-up delay
The selected device number (default: 1) affects the power-up delay of the device. This is
useful if a large number of CLVs (e. g. in the SICK network) are to be supplied from one
power source.
Table 5-9 contains a list of the available intervals.
