Note down the value of all parameters, reset the inverter to factory settings; see paragraph 7.3. The reset operation deletes

all inverter parameters, including the password.
Note down the number on the password page, send an email with this number to the local service centre, and a new

password will be sent within a few days to unlock the inverter.
6.6.16.1
Multiple inverter system password
The parameter PW is one of the sensitive parameters, and therefore must be identical for all inverters to ensure inverter operation. If
there is already a chain with aligned PW, and inverter is added with PW=0, a request is displayed to align the parameters. In these
conditions, the inverter with PW=0 can implement the configuration including the Password, but cannot propagate this configuration.
In the case of unaligned sensitive parameters, the key parameter with relative value is displayed in the parameter alignment page to
aid the user in checking whether a configuration can be propagated.
The key represents a password code. Depending on the key correspondence, the user can check whether the inverters in a chain can
be aligned.
Key equal to - -
the inverter can receive the configuration from all
•
the inverter can propagate its configuration to inverters with key equal to - -
•
the inverter cannot propagate its configuration to inverters with keys other than - -
•
Key greater than or equal to 0
the inverter can only receive the configuration from inverters with the same key.
•
the inverter cannot propagate its configuration to inverters with the same key or with keys = --
•
the inverter cannot propagate its configuration to inverters with different keys.
•
When the PW is entered to unlock an inverter in a group, all inverters are unlocked.
When the PW is modified on one inverter in a group, the modification is applied to all inverters.
When password protection is applied to one inverter in a group (+ and – in the PW page when PW≠0), protection is applied to all
inverters (the password is required to apply any modifications)
