Obtaining The Service Level Password; Resetting The Inverter/Switchbox Association - ABB TRIO-20.0-TL-OUTD-S-US-480 Product Manual

O
btaining the service level password
An advanced password can be provided to authorized installers to allow access to the service menu, upon
completion of required documentation. Contact ABB technical support at 877-261-1374 to request this password.
The password obtained is valid for 15 days.
NOTE! Because the service level password is date sensitive, it is necessary to have the correct date
and time set on the inverter display to successfully use the password. Refer to the Settings menu in
section 4 for instructions to set the date and time.
The password to access the Service menu is to be used by trained service personnel only. It is based on data
associated with a specific serial number and different for every inverter.
Locate the following information, which is necessary to generate the
password, from the product label of the inverter as shown in the label
example to the left.
• Serial number - SN
• Week of manufacture -WK
The same data can also be found on the INFO menu on the inverter display.

esetting the inverter/switchbox association
The inverter chassis and wiring box are automatically associated at first installation by the internal software. If the
inverter chassis/wiring box pair are disassociated from one another due to replacement of the wiring box or inverter,
the new system part will need to be associated with the old system part.
Once the new parts are assembled and the inverter control power (from DC side) is connected, the following
message will be displayed to indicate the disassociated state:
To allow the inverter to operate properly, the new component (inverter or wiring box) must be logically associated
with the original component.
The association of the parts comprising the inverter is carried out as follows:
1. Open the AC connection using an external switch or circuit breaker.
2. Ensure the DC switch is closed and there is sufficient energy to power the inverter controls.
3. Access the SETTINGS menu by entering the first-level password (default 0000) .
4. Set the date and time in the Date/Time sub-menu.
5. Access the Service sub-menu by entering the service menu password (described above).
6. Select menu item Accept Boards to associate the two parts of the device.
7. Use the ESC key to exit out of the menu.
Once the above steps have been carried out the inverter/wiring box pair will be properly associated and the system
will resume its normal operation automatically.
