Line reactor:
In order to use the ZAdynpro safely and in compliance with standards, a
power choke of type ND... from ZIEHL-ABEGG SE must be integrated into
the power line.
Use the following power chokes, depending on the frame size of the ZAdyn-
pro:

Residual current operated device (RCCB)
Frequency inverters of the ZAdynpro type do not require an FI circuit breaker for operation.
The circuit at the ZAdynpro output is monitored by an electronic short-circuit protection. On detecting
a short-circuit current at the output of the ZAdynpro (and thus negligible impedance between the
phase conductor and a body or the protective conductor of the circuit or the protective conductor of
the operating equipment 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 ZAdynpro and the motor was performed
according to the valid standards (VDE0100-Part 540:2012-06 and DIN EN 50178:1997), this behav-
iour is suf
fi
cient for the automatic switch-off in the case of an error demanded by VDE 0100-4100.
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 a reference fault current of 300 mA for
fi
re prevention according to
regulation VdS 3501.
Information
Please note that even when using a correct FI circuit breaker of type B, false tripping due to high
protective earth currents (leakage currents) can still occur.
