Internal voltage supply
) Note!
Internal voltage supply has been selected in the case of standard devices with
an extended AIF interface opening (e.g. front of 8200 vector). The area shown
on a grey background in the graphic marks the jumper position.
ƒ By default, this is not supplied internally in the standard device.
ƒ For internal voltage supply place the jumper on the position indicated
below.
In the case of all other device series (9300, ECS), voltage is always supplied
from the standard device.

(Only external voltage supply possible.)
Internal voltage supply
External voltage supply
) Note!
In the case of an external voltage supply and for greater distances between
the control cabinets, always use a separate power supply unit (SELV/PELV) that
is safely separated in accordance with EN 61800−5−1 in each control cabinet.
The external voltage supply of the communication module ...
ƒ is required if communication via the fieldbus is to be continued in case the supply of
the standard device fails.
ƒ is carried out via the 2−pole plug connector with screw connection (24 V DC):
Terminal Description
V+ External voltage supply
V = 24VDC±10%
I = 100 mA
GND Reference potential for external voltage supply
ƒ The parameters of a basic device disconnected from the mains cannot be accessed.
