For deselecting the load balancing option of the auxiliary inverter settings
disable the option ‘Balance load’ in
[/Welcome/Settings/Customer set./Auxiliary settings/Aux. PFC/Bal.]
For more information on the main and auxiliary settings concept, refer to
Section 7.9.2.1
In multi-unit system consisting of only masters, the master unit with the lowest address
has to be used to control the complete system.
8.8 Step 7: Start the system
Fit the inverter top cover before starting the system.
The ESI-S contains a main contactor that is controlled by the inverter controller.
WARNING: Under no circumstances close the main contactor manually. Failure to
adhere to this guideline may result in physical danger and in inverter damage.
In order to start it with the ESI-Manager:
−
Press
repeatedly until the ‘Welcome’ screen is displayed
−
Highlight the inverter start/stop menu (‘ESI’ item in the list). In this menu, the
‘START’ indication should be present.
−
Press
. The inverter will ask confirmation and then it will start. The main
contactor should close within 30 seconds. One second after closing, the IGBTs
will start and the inverter will charge the DC capacitors in order to reach the
battery voltage. Once it reach it, the inverter will close the DC contactor and will
be connected to the battery without power flow.
−
The ‘START’ indication in the start/stop menu changes in a ‘STOP’ indication once
the inverter is running
Detailed information on the inverter start/stop menu can be found in
Section 7.7
Remarks:
−
If the start/stop menu reads ‘ACK. FAULT’ (i.e. ‘acknowledge fault’), the inverter
has encountered a fault that needs to be corrected before the inverter can be
started. Refer to
for troubleshooting the problem.
−
If the inverter when activating the start menu displays a message to indicate that
it is remote control mode, the inverter either has to be started by remote control
or the remote control mode has to be deactivated. More information about the
remote control functionality is given in
and
Section 7.9.2.4

If one of the units in a multi-unit inverter system does not switch on, the unit
