The cross sections of the supply lines must be adapted to match the connected
load of the control cabinet type and cable lengths and must be protected by a
suitable circuit breaker. The electrical data is included in your project-specific

section of the PE conductor must be observed.

the respective project.
A control signal must be transferred to the controls during emergency-power
