2.6 Power bus
The power bus supplies RAMO5 and RASP5 Rapid Link modules with
power. Plug-in outgoers can be quickly and safely connected at any point
along the bus. The power bus can consist either of a flexible busbar (ribbon
cable) or standard round cables.

Observe the following when planning the lengths of the power bus cabling:
•
In the event of a single-pole short circuit at the end of the energy bus,
e. g. in the motor terminal board of the last user, the upstream protec-
tive device must be triggered. The level of short-circuit current depends
on:
•
Cable length,
•
Conductor cross-section,
•
Short-circuit current at the incoming point
•
The level of the application-specific voltage drop depends on:
•
Cable length,
•
Conductor cross-section,
•
Current consumption of motors
ATTENTION
•
All devices connected to the apparatus and data bus must
also meet the requirements for safe isolation according to
IEC/EN
60947-1 Annex N or IEC/EN
60950.
•
Power supply units for the AS-Interface power supply must
meet the safe isolation requirements according to SELV.
