Note: If the signs of active and reactive power are examined, it can be defined the quadrant that MMW03 measures. In order to understand P and Q signs in MMW03-CH, instantaneous displays for P and Q must be checked. If active power display is seem constantly, it means active power(P) is positive. If it is blinked, it means active power(P) is negative.
2.2 MOUNTING MMW03-CH is placed vertically into the gap located in the panel. After the product is placed into the panel, fixing brackets should be installed on the product. After that it should be fixed to the panel wall with the screws.
