Warning
Hazardous voltages! These may cause electric shock and burns.
Disconnect the system and device from the supply before starting work.
3.2.1
Selecting the power leads
The core cross-section of the power leads must be matched to the respective
ambient conditions. The decisive factors for choosing the core cross-section are
as follows:
• set current on the device
• method of installation
• ambient temperature
• type of material (PVC, rubber)
For PVC power leads installed in a cable duct, for example, the maximum cur-
rent carrying capacity as a function of ambient temperature is as follows:
Observe the following rules when carrying out wiring:
