Usage information
for residual current circuit-breakers of series
DFS 6 A EV OCP
These installation and operating instructions are aimed at qualified
electrical specialists. The installation of devices of this type is not ap-
propriate for electrical laypersons due to the considerable potential
dangers. These installation and operating instructions must be re-
tained, so that they can be referred to at a later stage. The operator of
the electrical installation must be informed about the application and
function of this protective device.
Application instructions and warnings
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. Corro-
sive gases are chlorine, ammonia and sulphurous air, for example. Residual cur-
rent circuit-breakers with "HD" specification are recommended for environments
affected by corrosive gases.
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 operational leakage currents or atmospher-
ic interference cannot be ruled out with absolute certainty. The conse-
quences must be considered and countermeasures taken where necessary.
Selective residual current circuit-breakers as well as surge protection measures
and system optimisations can provide a remedy.
6. If the residual current circuit-breaker 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 (WEEE/
German Electrical and Electronic Equipment Act).

Intended use
DFS 6 A EV OCP series protective devices are residual current circuit-breakers with
integrated over-current protection. They provide protection through automatic
switch-off in electrical systems, e.g. in accordance with VDE 0100 part 410. Their
main use is to protect against DC residual currents greater than 6 mA DC as per IEC
62955. 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 also
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. The odd-numbered terminals are used
for the supply. The device must be installed on a mounting rail (TS 35) according to
DIN EN 60715 in distribution boards or charging devices that have to ensure protec-
tion against direct contact (which may be required depending on the location of use)
and protection against environmental influences. A back-up fuse of max. 80 A gG
should always be provided for the operation of the DFS6 A EV OCP.
Testing and functional check
After the mains voltage is switched on, the LED for 'DC detection operation' should
light up green and the LED for 'Over-current detection operation' should light up
green or yellow (see 'Operation indicator LED 2 over-current detection operation').
A simple function test can be carried out with the assistance of test key T. When the
key is pressed, the DFS 6 A EV OCP must trip without noticeable delay. The toggle is
then in the middle position. Resetting to position '1' is only possible if the toggle has
first been moved down to position '0'. If tripping does not occur, the device must be
replaced immediately.
Additional functions
The 'DC detection operation' LED is referred to below as LED1 and the 'Over-current
detection operation' LED is referred to as LED2.
Over-current release
» The over-current release is based on characteristic C as per DIN EN 60898.
Depending on how high the over-current is, a switch-off is therefore triggered
after various tripping times. The end of this time (min. 40 ms / max. 120 minutes)
is indicated by LED 2 slowly flashing red.
» The over-current release can be switched from 16 A to 32 A. When a voltage of 12
to 24 V DC is applied to the 16 A/32 A terminals, it switches from 16 A to 32 A – LED
2 then lights up yellow. If no voltage is applied to the 16 A/32 A terminals and/or
no lines are connected to this input, the over-current release is set to 16 A – LED
2 then lights up green.

Trigger input
» The trigger input makes it possible for the DFS6 A EV OCP HD to be tripped
remotely when a voltage of 12 to 24 V DC is applied. A charge controller could
trigger an emergency switch-off via this input, for example.
» In the event of a continuous signal, an immediate switch-off is effected following
a switch-on.
Tripped output
» Following a manual switch-off (e.g. by hand or using the test key) or a
trip as a result of a residual over-current, the tripped output is active.
This is activated as soon as the toggle is no longer in the switched-on position.
Fault output
» The fault output is set as a result of an internal equipment failure and LED 2 flash-
es quickly. If this output is not reset after an interruption to the power supply, the
DFS6 A EV OCP is faulty and must be replaced.
» Example: A switch-off due to an over-current or the trigger input has failed.
» Tip: Non-tripping due to a residual current is not detected.
Operation indicator LED 1 'DC detection operation' and LED 2 'Over-current
detection operation'
If the operation indicators do not light up with the correct supply, the
DFS6 A EV OCP is faulty and must be replaced.
Operation indicator LED 2 'Over-current detection operation'
The operation LED is used to indicate different states:
» Green:
Ready, over-current tripping 16 A
» Yellow:
Ready, over-current tripping 32 A
» Red, flashing slowly (1 second on/off):
Load current exceeded, a trip will follow
» Red, flashing quickly (0.2 second on/off):
Fault, fault output is set
Warranty
All professionally installed, unaltered devices are covered by warranty for the dura-
tion of the statutory warranty period from the day of purchase by the end user. The
warranty does not apply to damage incurred during transport or caused by short-
circuit, overloading or improper use. Should any defects in workmanship or mate-
rial 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.
