To cancel the password timer, enter the PW page and press + and - at the same time for 2 seconds.
On entry of the correct password, an opened padlock symbol appears, while on entry of the incorrect
password will display a flashing padlock symbol.
If the incorrect password is entered 10 times consecutively, the same padlock error symbol appears with
inverted colours, to indicate that no password will now be accepted until the unit is switched off and on again.
After the factory settings are restored, the password is reset to "0".
Any change to the password is applied when Mode or Set is pressed, and any subsequent change to a
parameter requires entry of the new password (e.g. the installer makes all settings with the default PW value
= 0, and the last thing he/she does is to set the PW so that the machine is totally safe without any further
actions).
If a password is lost, there are two options to modify the inverter parameters:

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)
