All alarms are configurable to provide fault ride through capability to prevent nuisance tripping. The unit allows full compliance with relevant grid codes such as BDEW including G59/3 and G99.

THE MP250 DISPLAYS IT'S OPERATING STATUS AND ALARMS VIA AN LCD DISPLAY AND LED INDICATORS. OPERATION AND ALARM RESET IS BY FRONT MOUNTED PUSH-BUTTONS. PARAMETERS ARE ACCESSIBLE FROM EITHER THE FRONT PANEL OR BY CONNECTION TO PC USING THE BOARDPRG SOFTWARE.
