3 Installation
!
The terminals of the FE260 are freely accessible on opening the housing. To avoid
damage to the device, it must be ensured that no electrostatic discharge (ESD)
from persons via the FE260 can occur.
To prevent this, the installer should discharge himself by touching an earthed
metallic object directly before connecting a cable.
!
After installation replace all unused cable glands by the enclosed plugs to ensure
that the housing is sealed.
3.1 Power supply to the FE260
3.1.1 "AC" versions (for alternating voltage 230 V or 115 V)
!
The "AC" versions of the Function Expansion Unit FE260 are supplied with
mains voltage at 230 V or 115 V. Avoid touching live parts, because this can
be highly dangerous.
Switch off the mains voltage before starting installation or wire connection
work and before opening the housing.
Only switch the mains voltage on again after all the work has been
completed and the housing has been firmly closed.
Mains alternating voltage should be connected to the terminal block labelled "230V" or
"115V" and the earth conductor should be connected to "PE".
!
Depending on the version, the FE260 is suitable for power supply of 230 V
or 115 V alternating voltage. In order to avoid damaging the device, only
connect the voltage labelled on the terminals.
3.1.2 "DC" version (for direct voltage of 10 to 30 V)
The "DC" version of the FE260 is suitable for a direct-voltage power supply in the range
from 10 to 30 V. It can be operated, for example, with nominal voltages of 12 V or 24 V.
The "DC" version (not the "AC" versions) have the possibility of monitoring the supply
voltage on the terminal "10...30V". In this respect, the terminal "DE3" must be connected
to the terminal of the same name on the volume corrector. (

The monitoring can be set for nominal voltages of 12 V and 24 V. For further details: see
Chapter 4.1.
