1Description
The FHA2054 audio transformer kit is for a reliable ground disconnection of the
low-level audio source in booster amplifier station EBA2001. The FHA2054 audio
transformer kit is installed in booster amplifier station EBA2001 and must be
connected to 'Line in' 'X4' at the booster amplifier mainboard (100 W) EBA2004.
The FHA2054 comes with all individual parts for installation.
The kit contains a shield connection terminal block, an isolating transformer
module with connector for the low-level audio connection, a terminating resistor for
supervision and a terminal block for the wiring to the low-level input.
Properties
●Ensure solid Earth Ground connection
●Allows for terminal landing of shielded cables
●Uses 1:0.75 audio transformer with low distortion and good frequency response
●DC decoupling, impedance of 10kΩat 1kHz
●Allows DC wire supervision and ground fault detection of audio source
●Allows 1.00/1.55 Vrms operation
●Harmonic Distortion: <1 %
●Crossover distortion: <1%
You will find more information on booster amplifier mainboard (100
W)
EBA2004-A1 in document A6V10407858, e.g. requirements for installation and
complete installation instructions.

3Preparing and installing the cable
Preparing the external cable
Figure 2: Stripping the external cable for FHA2054
wUse a twisted, shielded cable.
1. Cut open the insulation approximately 90 to 110 mm/3.5" to 4.3" from the end
of the cable and remove the insulation approximately 20 mm/0.8" from the
cable.
2. Strip approximately 30 mm/1.18" from the end of the cable.
3. Open the wire braid of the shielding at the end of the cable and expose the
wires.
4. Cut off the wire braid of the shielding at the end of the surround corresponding
to the 'cut shield' in the figure.
Preparing the internal cable
Figure 3: Stripping the internal cable
wUse a twisted cable with a max. length of 170 mm/6.7", shielding is not
necessary.
1. Strip approximately 30 mm/1.18" from the ends of both cables.
2. Open the wire braid of the shielding and expose the wires.
3. Cut off the wire braid of the shielding at the end of the surround corresponding
to the 'cut shield' in the figure.

5Internal twisted cable
6 Booster amplifier mainboard (100 W) EBA2004
1. Lay the external shielded cable (3) so that the exposed braid is positioned in
the shield connection terminal block (2).
2. If necessary, lay a further shielded cable through the same shield connection
terminal block.
3. Tighten the knurled screws for the shield connection terminal block to fix the
cable in place.
4. Connect the external cable (3) to the plug terminal X41, in accordance with
chapter Wiring and pin assignments [➙10].
5. Lay the internal cable (5) in accordance with the figure above.
6. Connect the internal cable (5) between X42 of the FHA2054 (4) and X4 of the
EBA2004 (6), in accordance with chapter Wiring and pin assignments [➙10].

Figure 6: Wiring the plug connections of the FHA2054 audio transformer kit
*The audio line can be monitored by connecting an EOL resistor of 3.3 kΩ,
Siemens part no. C24235-A1-K14. The supervision and the appropriate EOLR
value are determined by the 'External source'.
Settings on the EBA2004
The DIP switch S1601-5 'FAULT TBL: LINE', must be set to OFF. A fault with LED
H401 is not signaled on the booster amplifier mainboard (100 W).
The following DIP switches must be configured, see DIP switch S1501/S1601,
configuration:
●S1501-5 'PRIORITY: LINE/SPEAKER'
●S1501-7 and S1501-8 'LINE INPUT LEVEL', recommended 0.75VRMS
You will find detailed information on the configuration and wiring of the EBA2004 in
document A6V10407858, Booster Amplifier Mainboard (100W) EBA2004.
