Starting and stopping the inverter
The ESI-S contains a main AC contactor and a DC contactor that are controlled by the
inverter controller. These contactors should never be activated manually for normal
inverter operation.
WARNING: Under no circumstances close the AC and DC contactor manually. Failure to
adhere to this guideline may result in physical injury and/or in inverter damage.
Normally, the commissioning engineer has set up the inverter and the desired inverter
requirements. As a result, the user only has to start and stop the inverter. Detailed
information on the inverter start/stop menu can be found in
9.2.1 Starting the inverter with the ESI-Manager
In order to start the inverter with the ESI-Manager follows the instructions given below:
Ensure that power is supplied to the system and that the inverter auxiliaries are

Highlight the inverter 'start/stop' menu ('ESI' item in the list). In this menu, the
'START' indication should be visible.

contactor should close within 30 seconds and one second after closing, the IGBTs
will start. The inverter will increase its DC voltage in order to reach the battery
voltage then it will close the DC contactor. This operation may take up to 30 sec.
After this operation the system is ready to charge or discharge the battery.
-
The 'START' indication in the 'start/stop' menu changes in a 'STOP' indication
once the inverter is running
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 system can be
started. Refer to
consisting of more than one unit, an ACK. FAULT message will only occurs when
all the masters in the system have failed.
-
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
on the ESI-Manager repeatedly until the 'Welcome' screen is
. The system will ask confirmation and then it will start. The main AC
