Connecting electrical cables
WARNING
Risk of injury due to electric shock.
• For the electric power supply, use SELV or PELV circuits that guarantee a reliable electric disconnec-
tion from the mains network.
• Observe IEC 60204-1/EN 60204-1.
1. Switch off the power supply.
2. Observe the tightening torque of the cables, e.g. hook spanner with torque adjustment.
3. Seal unused connections with cover caps.
7.3
Power supply
As part of the EMERGENCY STOP concept, check which measures are required for the machine/system
in order to put the system in a safe state in the event of an EMERGENCY STOP, e.g. shutdown of the
load voltage.
The power to the automation system is supplied by feeds in the interlinking modules. They forward the
operating voltage and the load voltage to the adjacent modules.
The voltages can be supplied jointly by one fixed power supply or separately by two fixed power
supplies.
