    To minimize high levels of EMI the signal ground connection at the field I/O port (pin 50) should be used to provide a path for induced common- mode noise and currents.

    Surface-Mounted Technology (SMT) boards are generally difficult to REPAIR repair. It is highly recommended that a non-functioning board be returned to Acromag for repair. The board can be easily damaged unless special SMT repair and service tools are used. Further, Acromag has automated test SERVICE AND REPAIR equipment that thoroughly checks the performance of each board.
