Warnings and block diagram

The arrangement of the connecting elements can be seen in figure 4-7, page 125.
!
WARNING
The "Regulations for the installation of power systems with rated voltages
under 1000 V" (VDE 0100) must be observed in the electrical installation!
D PE conductor connection
Connect the PE conductor to the ground screw (see figure 4-8, page 128) on the back of the
controller. When connecting to 115 or 230 V AC-mains supply, the PE conductor can also be
connected through the three-pin plug (see figure 4-9, page 129). The controller's ground-
connection may also be connected with the PE conductor (grounded extra low voltages).
!
WARNING
Disconnection of the PE conductor while the controller is powered up can make
the controller potentially dangerous. Disconnection of the PE conductor is
prohibited.
D Power supply connection
The power supply is connected on 115 V AC or 230 V AC systems by a three-pin plug IEC
320/V DIN 49457 A, on 24 V UC systems by a special 2-pin plug (polarity irrelevant). The
mains plugs are part of the scope of delivery.
!
WARNING
Set the mains voltage plug-in jumpers (see figure 4-2), page 122 in the no-vol-
tage state to the existing mains voltage.
It is essential to observe the mains voltage specified on the rating plate or by
the mains voltage jumpers (115/230 V AC) or on the voltage plate (24 V UC)!
Lay the power cable through a fuse; limit the rating (fire protection EN 61010-1)
to ≤ 150 VA. Limit the mains voltage alternatively to 30 V at 24 V UC.
