Installation and Operating Manual

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

in DFS 4 A EV model ranges

Intended use

DFA 4 A EV is a type A residual current circuit-breaker with integrated additional de-

vices that disconnect the switching contacts of the RCCB when smooth DC residual

currents > 6 mA are detected. They are only suitable as protective devices for the

power supply of electric vehicles as per HD 60364-7-722 in charge operating mode 3

according to EN 61851-1.

Mounting

Mounting is carried out by snapping onto a mounting rail for installation in distri-

bution boards with suitable device covers to prevent contact with dangerous active

parts.

Electrical connection

Guide all active conductors (outer cables L1, L2, L3 and the neutral conductor MP/N)

through the switch. The input terminals are 1, 3, 5, 7; the consumer system side is 2,

4, 6, 8. For two-pole applications, two-pole residual current circuit-breakers must

be used. Scrape and grease aluminium conductors immediately before connection.

Integrated additional device

The integrated additional device, which depends on the auxiliary voltage, detects

smooth DC residual currents. If these currents exceed 6 mA, the additional device

isolates the switching contacts of the residual current circuit-breaker. The LED in-

dicates that the additional device is active. The additional device is supplied via an

adaptor circuit integrated at terminals 1, 3 , 5 and 7. An alternating voltage > 85 V

must be present at these terminals for the additional device to function properly. If

the LED does not illuminate, then only tripping via type A residual currents is still

guaranteed.

Testing and functional check

An insulation test of the user equipment is to be carried out in accordance with DIN

EN 61557-2. This may only be done when the device is switched off. Insulation test-

ing when the device is switched on or insulation testing on the input side may lead

to incorrect measured values. A functional inspection of the residual current circuit-

breaker itself is possible with connected mains voltage by pressing the test button T

and, as in commercial use (BGV A3), 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.

Application instructions and warnings

The following notes and warnings must be observed in order to ensure safe opera-

tion:

1. Installation may only be carried out by an electrician who is familiar with the rel-

evant national installation regulations.

2. Without any additional protective housing, residual current circuit-breakers

should only be stored and operated in a dry, low-dust environment. An aggressive

atmosphere must also be avoided.

3. The user must be made aware of repeat testing using the test button T.

4. Please be aware that the short-circuit back-up fuse (SCPD) does not ensure 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. Trips due to leakage currents caused by surge voltage cannot be completely ruled

out. 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 upstream surge arresters. In spe-

cific cases, the switching status should be monitored by means of an auxiliary con-

tactor at the residual current circuit-breaker and an appropriate signalling device.

Important information on tripping with pulsating DC residual currents (type A)

Pulsating DC residual currents also contain a constant part (DC) in addition to

spectral parts of the mains frequency and their fluctuations. The integrated

additional device, depending on its physical setup, cannot differentiate be-

tween a pure smooth DC residual current and the constant (DC), spectral part

of a pulsating DC residual current and thus evaluates these in the same way.

If the additional device is active, pulsating DC residual currents will therefore

cause a premature trip (see table part "Effective value of tripping threshold").

The switch-off times stipulated in relevant product standards and installation regula-

tions remain unaffected by the integrated additional device.

Warranty

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

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

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

overloading or improper use. In the event of defects in workmanship or material,

which are 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.
