Installation and operating instructions

for two-/four-pole residual current circuit-breakers

in the DFS F Audio series

These installation and operating instructions are aimed at qualified

electrical specialists. The installation of devices of this type is not

appropriate for electrical laypersons due to the considerable potential

dangers. These installation and operating instructions must be

retained, so that they can be referred to at a later stage. The operator

of the electrical installation must be informed about the use and

function of this protective device.

Application instructions and warnings

The following notes and warnings must be observed in order to ensure safe operation:

1. Devices with visible damage must not be installed or used.

2. Operation must only occur under normal ambient conditions free of corrosive

gases in order to preserve the correct tripping function in the long term.

Corrosive gases are chlorine, ammonia and sulphurous air, for example.

3. The user must be made aware of regular function testing using the test key T.

4. The function test with the test key is not a substitute for regular testing of the

electrical system.

5. Erroneous tripping due to operation related leakage currents or atmospheric

interference cannot be ruled out with absolute certainty. The consequences must

be considered and countermeasures taken where necessary.

6. If the RCCB cannot be switched on, or if the consumer network is not connected,

the device must be replaced.

7. Disposal is subject to the statutory regulations of the European Union (waste of

electrical and electronic equipment (WEEE)).

Intended use:

DFS 2 and DFS 4 series protective devices are residual current circuit-breakers

without integrated overcurrent protection. They provide protection through

automatic switch-off in electrical systems, e.g. in accordance with VDE 0100 part

410. They meet the requirements for residual current protection in accordance with

their characteristics on the name plate. The switch-off function can be tested using

a push-button which is also accessible to laypersons. Regular testing can increase

the endurance of the circuit-breaker, as the mechanism of the latch is moved when

tripped in addition to the electrical test.

Electrical connection and installation:

The electrical connection must be as shown in the wiring diagram and must comply

with the terminal designation on the device. If the device is to be operated without

using all poles, it is essential (in order to ensure the connection is correct) to observe

the position of the test key as per the wiring diagram and the operating voltage

range of the test circuit in accordance with the data sheet. DFS 4 devices have a

N-left design as standard. N-right devices have a 'R' in their designation. The device

must be installed on a mounting rail (TS 35) according to DIN EN 60715 in distribution

boards that have to ensure protection against direct contact (which may be required

depending on the location of use) and protection against environmental influences.

Testing and functional check

A simple function test with the assistance of test key T should be carried out after

the mains voltage and the circuit-breaker are switched on. When the key is pressed,

the DFS 2/DFS 4 must disconnect without delay; the toggle is then in centre position.

Resetting to position '1' is only possible if the toggle has first been moved down to

position '0'. The operation indicator beneath the toggle indicates the status of the

contacts: red = closed, green = open.

This test must be carried out at least every six months where the device is used as

intended and must be repeated every working day for non-stationary systems

according to the regulation. If tripping does not occur, the device must be replaced

immediately. The operator must be informed of this. All additional tests are covered

by the prescribed acceptance test. Tests should be carried out according to DGUV

Regulation 3 (BGV A3) depending on the location. The insulation test should be

carried out using test devices according to DIN EN 61557-2.

Guarantee

All professionally installed, unaltered devices are covered by warranty during the

statutory guarantee period from the day of purchase by the end user. The guarantee

is not applicable to damage incurred during transport or caused by short-circuit,

overloading or improper use. Should any defects in workmanship or material

be discovered within the warranty period, the company will provide repair or

replacement free of charge. The warranty will be rendered null and void if the device

is opened without authorisation.

Recommendations for the power supply of audio systems in conjunction with the

DFS F Audio, with a view to improving sound:

The following recommendations must only be implemented by an authorised and

qualified electrical specialist, who is familiar with the applicable national installation

regulations. The recommendations exclusively refer to the circuit for connecting an

audio system. Priority should always be given to ensuring that electrical installations

are correctly implemented in line with the applicable installation regulations, over

any sound objectives.

» Use an outer conductor (L1, L2 or L3) that is used by as few other electrical

consumers (e.g. lights or household appliances) as possible.

» If possible, use a separate installation cable from the distribution installation

to the installation socket to which the audio system is connected. No further

electrical consumers should be connected to this circuit.

» When using multiple residual current circuit-breakers in a distribution installation,

the DFS F Audio should be connected on the input side, if possible directly, to the

connection cables from the meter board. Further residual current circuit-breakers

can then be connected on the input side, e.g. with suitable busbars.

» Connect the phase conductor to which your audio system is connected to the

output side (load side) of the DFS F Audio via a suitable overcurrent protective

device.

» Through use of a busbar fork, it is also possible to connect to the upper wiring level

for the DFS F Audio. This refines the sound image somewhat but does reduce the

volume a little.

» When connecting the neutral conductor to which your audio system is connected,

avoid having a lot of terminal positions in the neutral conductor path. If necessary,

it is possible to connect the neutral conductor directly to the neutral conductor

pole terminal on the output side (load side) of the DFS F Audio instead of to

the neutral conductor rail on the distribution board. This adds volume and

authenticity to the audio image without losing precision.

» If the installation cable to your audio system in the distribution installation needs

to be extended or connected to installation terminals, avoid using ferromagnetic

materials (e.g. copper-covered steel) as direct live parts. However, parts that

are not directly conductive that are used to mechanically secure electrical

conductors, e.g. clamping screws made from ferromagnetic material, have no

adverse effect on sound.

Hints:

» The audio image may initially seem rather unsettled following installation and

wiring work on the distribution board. This will subside after a few operating

hours.

» In comparison to standard residual current circuit-breakers, the DFS F Audio

provides a stable and clear audio image, without lessening the volume or

musicality. The sound is, however, affected by many factors relating to an audio

system's power supply and, of course, by the components in an audio system and

can therefore vary.

» If mains filters are in place at the output side (load side) of the DFS F Audio, in

many cases, depending on the type of filter, it may be necessary to disconnect

them from the mains if the audio image is clearly defined but too thin.

Break-in time of the DFS F Audio:

» Immediately after it is first commissioned, the audio image can seem more

lightweight, particularly in the low range.

» After around two to three operating hours, the audio image increasingly gains

in volume.

» The full potential of the sound is achieved after around 50–100 operating hours.

An audio system does not necessarily have to be active during this time.

» The residual current protection function of the DFS F Audio is of course available

immediately after installation and at all times.
