P.294 is the parameter that provides the decrypt function. P.294 will be zero if the decryption is
successful. Use P.295 to set the password. Enter the initial password into P.294 to decrypt the
parameter password and to modify or to set up various parameters.
•
P.295 is the parameter for setting up the password. The password has to be greater than 1. Once the
password setup is completed, P.295 will display 1. After deleting the password, P.295 will display 0.
Once the password is set, no parameter can be modified, except P.294.
P.998
and power shutdown
have no effect on the password. The parameters can be revised only after the decryption.
Note: Bring the inverter to the factory for decryption if the password is forgotten.
