  • Page 4: General

    Section 1: GENERAL The power factor controller BR7000 is the consequent follow-up development of the well proven series BR6000. The main distinctive feature is the new 3-phases measuring system. Due to the 3-phases recording of voltage and current the device allows a convenient usage as grid measuring device and as power factor controller.

  • Page 5: Installation And Instructions For Usage

    Section 2: INSTALLATION AND INSTRUCTIONS FOR USAGE The BR7000 is designed as panel mounting instrument in PFC-systems. This requires a cut out of 138 x 138 mm according to DIN 43700 / IEC 61554. The controller has to be inserted from the front and fixed with the clamps (included in delivery). The device may only be installed by qualified personnel and may only be operated according the given safety regulations.

    12.2 EXPERT-MODE 2 ( Code: 2244 ) The 2nd expert mode defines all operation-, warning- and fault messages which can be displayed by the BR7000. They can be activated/de-activated separately. When de- activated, the display of the message as well as the possible activation of the alarm-relay or consequent effects on the control behavior are suppressed.
