Installation and Operating Manual
for residual current circuit-breakers
of series F204…-125/…
General
In order to avoid personal injury and damage to property, the operating manual
must be read carefully before using the residual current circuit breaker. The
manual must also be retained for future reference. Installation may only be car-
ried out by an authorised specialist who is familiar with the relevant national in-
stallation regulations.
Intended use and mounting
For snapping onto mounting rail and for installation in distributions board with
corresponding device covers, to prevent contact with dangerous active parts.
Electrical connection
Guide phase and all outer conductors (L1, L2, L3) and the neutral conductor
(MP/N) through the switch. Energy may flow in either direction, i.e. the mains or
consumer unit may be connected to the upper or lower terminal block. To ensure
that the installed testing facility functions correctly, for two-pole connection four-
pole devices, the terminals must be used in accordance with the wiring diagram.
Scrape and grease aluminium conductors immediately before connection.
Testing and functional check
The testing of all safety measures during commissioning must be carried out
according to the information in the valid national installation regulations. A func-
tional inspection of the residual current circuit-breaker itself is possible with con-
nected mains voltage by pressing the test button T. As in commercial use (BGV
A3), it should be carried out at least every six months in the case of stationary
systems and should be repeated every working day in the case of non-stationary
systems. After tripping by pressing the test button or a system-specific residual
current, the toggle of the residual current circuit-breaker is located in the middle
position '+'. Resetting to position 'I' is only possible if the toggle has firstly been
moved to position '0'. The operating display beneath the toggle indicates the sta-
tus of the switching contacts. If the switching contacts are closed, the display is
red and it is green if the switching mechanism is open.
Application instructions and warnings
The following notes and warnings must be observed in order to ensure safe
operation:
1. Without any additional protective housing, residual current circuit break-
ers should only be stored and operated in a dry, low-dust environment.
Aggressive atmospheres must also be avoided.
2. The user must be made aware of repeat testing using the test button ‘T’.
3. Using surge current strength residual current circuit breakers cannot abso-
lutely guarantee to rule out trips due to leakage currents caused by surge
voltage. In cases where an interruption of the power supply may lead to
potential dangers for humans and animals or serious damage to property,
residual current protection should be implemented by means of increased
surge current strength, selective residual current circuit breakers and up-
stream surge arresters. In specific cases, the switching status should be
monitored by means of an auxiliary contactor at the residual current circuit
breaker and an appropriate signalling device.
4. Please be aware that the short-circuit back-up fuse (SCPD) does not en-
sure any thermal overload protection. Thermal overloading must be ruled
out as a matter of priority by means of thorough project planning or using the
specified thermal back-up fuse (OCPD).
5. When working on electrical systems, this fuse must always be activated and
the safety rules must be observed. Should there unexpectedly be any con-
tact with active parts, a doctor must be called immediately.
6. Disposal is subject to the statutory regulations of the European Union
(WEEE/German Electrical and Electronic Equipment Act).
7. Opening the device or removing the safety seal will invalidate the warranty.
8. Accessories: auxiliary switch F2-125A-B-S/H for new switch toggle or motor
drive F2…CM4
Notes for users
1. The test button 'T' must be used regularly to check the function of the residu-
al current circuit breaker. This should be carried out at least every six months
in the case of stationary systems and should be repeated every working day
in the case of non-stationary systems.
2. Recurrent testing of the protective measures must be carried out at regular
intervals by an authorised specialist.
3. After tripping by pressing the test button or a system-specific residual cur-
rent, the toggle of the residual current circuit breaker is located in the middle
position '+'. Resetting to position 'I' is only possible if the toggle has firstly
been moved to position '0'.
4. If the residual current circuit breaker can no longer be switched on in accord-
ance with the procedure indicated under point 3, an authorised specialist
must be contacted.
5. If any damage to the housing is identified, an authorised specialist must be
contacted.
6. Disposal must be performed by an authorised specialist and is subject to the
statutory regulations of the European Union (WEEE).
