** 8pr108the ÖVE / ÖNORM E 8001-4-712 can be parameterized by adapting the parameters

System-disconnection relay EU400 NA-protection
13
Subject to technical changes
Application and brief description
The grid- and plant protection device EU400 monitors voltage and frequency in three-phase networks . It
complies with the requirements of VDE-AR-N 4105:2018-11 or VSE NA/EEA-NE7 - CH 2020, in stand-alone
power generation plants for feeding into the low-voltage grid. For VDE-AR-N 4105:2018-11, the
corresponding parameters were stored in program 2 or for VSE NA/EEA-NE7 - CH 2020, in program 15, and
the monitoring of the coupling switch and the protection of the parameters were adapted accordingly
For supply to the medium-voltage network in accordance with VDE-AR-N 4110:2018-11 or in the high-voltage
network in accordance with VDE-AR-N 4120:2018-11, it is suitable as unit protection on generators and NA
intermediate protection, if no Q-U protection is required, a higher NA protection.
The device has a two-channel error-proof design and thus meets the requirements of VDE-AR-N 4105:2018-
11 and ASE RR/IPE-NR 7 - CH 2020. The function of the connected switch is monitored. If monitoring is
activated, the device does not restart if a shutdown fault is detected; if switch-on errors are detected, an
attempt is made to restart the system, which increases the availability of the system. Limit values for different
applications are predefined. They can be changed if required and be protected with a code and/or a seal.
With a test-button the function of the connected switches can be tested and their switching-time can be
measured. The standby input allows a remote shutoff e.g. with a RCR.
Summary of the functions
•Under and overvoltage monitoring 15…520 V
•Measuring phase-neutral or phase-phase
•Monitoring of under- and overfrequency 45…65 Hz
•Monitoring of quality of voltage (10-minutes-average)
•Monitoring of vector shift 2…65°
•Monitoring of rate of change of frequency (ROCOF, df/dt) 0,100...5,000 Hz/s
•Monitoring of zero voltage U0
•One-fault-proof with monitoring of connected switches (defeatable when using the integrated switch of
pv and battery inverter acc. to DIN EN 62109 (VDE 0126-4))
•2 automatic restarts at switch-on error
•Passive anti-islanding protection acc. to ch. 6.5.3 and app. D2
•Switching delay adjustable 0.05 … 300 s
•Switching back delay adjustable 0 … 6.000 s
•Switching back delay at alarms <3 s: 5 s
Preset values acc. to

8.1 1x PV, 1x section switch (VDE-AR-N 4105:2018-11)
1) Feedback contacts not connected: set 8rel .8→8trel.8→8oFF.8
2) N connected →only for programs with N
3) NC- or NO-contacts can be connected, self-learning when switching on
4) Switch off the plant without recording an alarm, e.g. with contact of a ripple control receiver
5) Fuses only when line protection necessary, e.g. 16 A
6) Contact closed an 8uSr .8→8StbY.8(default setting) = Standby, K1+2 switched-off
(e.g. by ripple control receiver or clock, …)
Contact closed and 8uSr .8→8on.8= repressed vector shifts
(e.g. when switching on …),
contact closed and 8uSr .8→8y1y2.8= no evaluation of the feedback contacts
(e.g. for synchronisation, …)
7) 1 phase Application connect L1-L2-L3, 2 phase Application L1 / L2+L3 (only Pr 5, 7, 10, 13, 20)
8) Additional switch-off of self generation plant.
Single-fault safety: shutdown of the self generation plant e.g. by ripple control input 0% with K2. Use
coupling relays ford contact multiplication of if safe isolation is required.
This second shutdown path must be tested separately during commissioning. (8tst28)
9) Power supply / buffering. Switches have to withstand undervoltage for min.3 s (FRT)
10) TT-system: switch all line conductors and N, TN-system: only switch line conductor
