5-1. Prepare for Parallel Usage
1. Before setting, you need to ensure that the main switch is ”OFF”.
2. Before using the parallel function, you need to set the parallel jump of the green
terminal the status of which must be “ON”, if the between in another ECB is set
to ”OFF” which is termination resistors.
Figure 24. Parallel jump setting
Example：If three ECB inverters are paralleled, setup green terminal.

If you parallel N units, the first (unit 1) and the last unit (unit N) must set parallel jumper in ON
position.(Refer to Figure 25.)
