Quick Manual / Practical(I)
Set parameters of EZA via RS-485.
Make sure that the specified voltage is applied to the grid side and the battery side,
and when discharging, check that the load such as the inverter is connected. Then
send the desired operation mode start command to EZA via RS-485..
The fan rotates and the main converter starts and starts power conversion.
To stop, send the Waiting command to EZA via RS-485.

When EZA start up, the green LED on the front panel lights up or
flashes.
After receiving the Waiting command, the main converter of EZA stops
immediately, but the fan continues to rotate for about 3 minutes for
cooling and then stops.
It is possible to overwrite (change) the parameters of EZA after startup.
After the end of reception from EZA, please start transmission with an
interval of 2ms or more for RS485. Also, for communication using a
broadcast address, make sure that the issuance command interval is
200ms or more. Note that EZA does not reply to commands using a
broadcast address.
After sending the start command, EZA11K requires about 9 to 16
seconds for the current and voltage to reach the set values.
