Before connecting the operating voltage, you
should observe the following:
• Calculate the complete current consumption
Caccording to the following table and select
both a suitable power unit and cable cross
section.
• Avoid long distances between the power unit
and the terminal. Calculate also the permitted
distance according to Appendix A.
The following rule applies for type 05:
