4.2.4 Emergency Stop
The emergency shut-off switch immediately disconnects the Sunny Central from the grid and the PV
generator, thus putting the Sunny Central in a safe state.
By pressing the emergency shut-off switch, the device is locked in the "Off" position. The emergency
shut-off switch can only be deactivated with the appropriate key. In addition, the activation of the
emergency shut-off switch must be cleared using Sunny Central Control or Sunny Data Control.
You can install an external emergency shut-off switch on each Sunny Central or connect several Sunny
Centrals via a shared emergency shut-off switch.
NOTICE!
Improper use of the emergency shut-off switch may cause damage to the Sunny
Central.
The components of the Sunny Central are subject to considerable stress if the emergency
shut-off switch is actuated under load. Frequent use of the emergency shut-off switch can
cause stress-related damage to individual components.
• Only use the emergency shut-off switch in an emergency.
• Switch off the Sunny Central with the key switch.
