When checking the phase rotation with a phase rotation meter, ensure that the
auxiliary fuse box is open during the measurement process.
WARNING: In a multi-unit inverter arrangement, care must be taken to connect
all units to the power supply in an identical way as the master unit (individual
phases and phase rotation). Otherwise, the equipment may be damaged upon
energization and/or may function incorrectly.
Before going to the next step, it is recommended at this stage to first install the other
I/O cabling if required.
Once all the hardware has been cabled,
-
Close the auxiliary circuit fuse box
-
Refit the unit protective cover including ESI-Manager and its connections
-
Close the inverter upstream protection
When the power is applied to the inverter:
- The DC capacitors will be charged
- The ESI-Manager will initialize and show the 'Welcome' screen (Cf.
or will show a screen indicating that it is in slave mode
If the voltage level or phase rotation is incorrect, the installation should be corrected
before applying power to the inverter to avoid potential inverter malfunctioning and/or
damage.

Step 4: Basic commissioning parameters set up (using ESI-
Manager)
In order to set up the basic commissioning parameters with the ESI-Manager, navigate
to [/Welcome/Settings/Commissioning] (Cf.
menus of the ESI-Manager is given in
The complete commissioning must be done at the first installation of a system and each
time a unit is added to an existing system.
If the window or some of its items are locked (i.e. a small
present on the screen), the hardware and/or software lock has been engaged. Refer to
Section 7.6
for more information on these features and for guidelines on how to unlock
the unit setting menus.
Note: In systems consisting of more than one master, the ESI-Manager of the master
that has the control over the system has full functionality and the ESI-Managers of the
other master units have limited functionality. In practice, the functions that are not
enabled on these units are also locked.
In the commissioning window, the following basic parameters have to be specified:
