Planning the electrical installation
5.3.1
Requirements for the host interface
The host interface of the CLP 100 is operated as an RS-232 interface. For the pin
assignment refer to
Table
Table 5-3
shows the recommended maximum cable lengths as a function of the data
transmission rate.
.
Recommendation
In order to avoid interferences, do not lay the cable parallel to the power-supply and motor
cables (for example in cable ducts).
5.3.2
Supply voltage
For operation the CLP 100 requires a supply voltage of 5 V DC
±
5 % in accordance with
IEC 742 (functional extra-low voltage). The power supply unit must also fulfil IEC 742 and
output a continuous output of 2 W.
