NOTE!
Refer to UM1C24481500 (Converter Module User Instructions) for converter module information.
Converter Operation
The converter modules, when used in this system, revert to their default overvoltage and overcurrent setpoints since they are
initialized without communications to a controller. Reference to a controller in the Converter Module User Instructions do not pertain
to this system, since this system is a stand-alone system and does not include a controller.
•
The selective overvoltage shutdown still functions, only the converter module causing the high voltage condition shuts down.
•
The converter modules will share load until each reaches its power limit (1500 watts) or current limit point (31.25 A)
