11.6 Protección contra la sobretensión
PELIGRO
¡Peligro de incendio por desconexión del módulo de sobretensión bajo carga!
Los bornes de conexión y los portafusibles se pueden destruir al desconectar el cable de conexión o extraer los
módulos a causa de arcos eléctricos.
ü Secuencia de conexión:
1. tensión de red mediante desconexión de los fusibles externos.
2. Desconecte el generador FV mediante el seccionador de CC.
3. ¡Los cables de CC siguen estando bajo tensión!
4. Compruebe que no existe corriente con una pinza amperimétrica en todos los cables de CC.
5. Abra el portafusibles solo después de comprobar si existe corriente en los cables de CC.
6. Verifique la ausencia de tensión en los bornes de conexión a la red.

Faults

11.7.1 Procedure
PELIGRO
Lethal voltages are still present in the connections and cables of the device even after the device
has been switched off and disconnected!
Severe injuries or death may occur if the cables and/or terminals/busbars in the device are touched.
1. If a fault occurs, notify an appropriately authorized and qualified electrician or KACO new energy GmbH
Service.
2. The operator can only carry out actions marked with a B.
AVISO
In case of power failure, wait for the system to automatically restart. Notify your electrician if there is an exten-
ded power failure.

Explanation/remedy
› Check whether the DC and AC voltages are within the permit-
ted limits (see Technical Data)
› Notify KACO Service.
If the grid separation relay is defective, the device will recogni-
se this error during the self-test.
› Ensure that there is sufficient PV generator power.
› If the grid separation relay is defective, have it replaced by
KACO Service.
› Notify KACO Service.
Due to a grid fault (over/undervoltage, over/underfrequency),
the device stopped the feed-in process and disconnected from
the grid for safety reasons.
› Change the grid parameters within the permitted operating li-
mits (see the "Start-Up" section).
