Password Protection
Safety-relevant Sunny Central parameters can only be adjusted when a code number is entered.
Our service team will provide you with the code number (see section 10 "Contact", page 102).
After this code number has been entered, you will be able to view and modify all parameters.
You can change the code number as you wish. Store the code number at a safe location so that no
unauthorized persons can change the parameters.
Entering the code number
Proceed as follows to enter the password:
1. Press the [Menu] and [Clear] button at the same time.
☑ The grid monitoring relay menu is displayed.
2. Navigate to the "Enter code number" menu with the [Display ↓ ] button.
Once the code level has been set, it will not be changed, even after repeated entry into configuration
mode. If an incorrect code number is entered, then the device is locked.
If the supply voltage is uninterruptedly present at the relay for 2 hours, the device locks automatically.
The configuration screen "Enter code number" appears only if the configuration screen "Password
