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 closed-sealing-inserts to
!
ensure that the housing is sealed. If you don´t use the M16 plastic gland, replace it by the
also enclosed M16 blind plug. That´s the only way to ensure the tightness of the housing!

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. (→ 0
Terminal layout, page 11).
The monitoring can be set for nominal voltages of 12 V and 24 V. For further details: see Chapter 4.1.

3.2 Screening and earthing

The cables for connection to the intrinsically safe electrical circuits (blue terminal block) and to the outputs
A1 to A4 have a screen which must be earthed at both ends to prevent interference due to high frequency
electromagnetic fields.. The screen must be connected all round, complete and flat. The FE260, similar to
the volume corrector (e.g. EK260 or EK280) to be connected, has special metallic EMC cable glands for this.
