EZA2500 series 

Quick Manual / Practical (III) 

 

Over view of Quick manual Practical Volume III 

 
Quick Manual Practical Volume III explains how to check the input / output 
current and voltage on the high voltage (grid) side and low voltage (battery) 
side of EZA2500, and how to check the details of alarms that occurred 
during operation of EZA2500.  
 
The EZA2500 uses a circuit that does not start unless a predetermined 
voltage (pre charge) is applied to both the high and low voltage sides. 
However, if the "Grid Ramp Up" or "Battery Ramp Up" function is used after 
adjusting the usage conditions, it is possible to start even if either the high 
voltage side or the low voltage side is 0V. This manual will explain that too.

1) Construction of communication environment with RS-485 
2) Alarm confirmation using CNVCommCC 
3) Checking the operation status using CNVCommCC 
4) Startup from grid side 0V using "Grid Ramp Up (Grid bus 
ramping up)" 
5) Starting from 0V on the battery side using "Battery Ramp Up 
(Battery bus ramping up)"
