5.4.5 Voltage supply
For DeviceNet always an external voltage supply is used.
Designation Explanation
V+ External supply (exceeds the selection of the DeviceNet specification)
V = 24 V DC (21.6 V - 0 % ... 26.4 V + 0 %)
I = 100 mA
V- Reference potential for external voltage supply
If the distance between the DeviceNet participants is larger than normal,
you can use several voltage supplies.
Controller External voltage supply
820X Always required
821X, 822X, 824X,
93XX and ECS
Only necessary, if the mains supplying the corresponding controllers is
to be switched off but the communication must not be interrupted.
8200 vector See “Internal DC voltage supply”

Note!
The internal voltage supply option is available for basic devices
with extended AIF interface opening (8200 vector front). The
area marked in grey in the graphic representation indicates the
jumper position.
ƒ In the delivery status of the frequency inverters, these are not
supplied internally.
ƒ For internal voltage supply put the jumper on the position
indicated below.
