5.7 Residual current operated device (RCCB)
Frequency inverters of the ZAdyn type require no FI circuit breaker for operation.
The circuit at the output of the ZAdyn4B is monitored by an electronic short-circuit protection. On
detecting a short-circuit current at the output of the ZAdyn (and thus negligible impedance between
the phase and a body or the protective earth of the circuit, or a protective earth of the operating
medium in the case of an error) the output current is switched off within a time of <20
μ
s. On condition
that the potential equalisation for the ZAdyn and the motor was performed according to the valid
standards (VDE0100-Part 540:2012-06 and DIN EN 50178:1997), this behaviour is suf
fi
cient for the
automatic switch off in case of an error demanded by VDE 06-4100
If an FI circuit breaker is required for special reasons (e.g.
fi
re prevention), an all-current sensitive FI
circuit breaker type B must be used. For maximum operational reliability ZIEHL-ABEGG recommends
the use of an FI circuit breaker with reference fault current of 300 mA for
fi
re prevention according to
regulation VdS 3501.
Information
Please note that even when using a correct type B RCCB, false triggering due to high protective earth
currents (stray current) can still occur and that operation with these protective devices is not possible.
5.8 Control transformer in the mains supply line
CAUTION!
Attention!
When using a control transformer in the power line of the ZAdyn4B, you must connect a capacitor
parallel to the transformer's primary winding (see
fi
g.).
The capacitor is used to prevent an extreme increase in voltage in case the voltage fails in one of the
phases to which the transformer is connected. This voltage increase can lead to destruction of the line
fi
lter. The cause of voltage increases is resonance of the control transformer with the radio-interfer-
ence suppression components, which are always used in frequency inverters.
