WARNING
Risk of electric shock or equipment damage!
Due to the risk of short-circuiting (see Fig. 23), it is strongly
►
recommended that the EAGLEHAWK NX controller be
supplied with power from a dedicated transformer.
However, if the EAGLEHAWK NX controller is to be
supplied by the same transformer powering other con-
trollers or devices (e.g., the PW M-Bus Adapter), care
must be taken to ensure that correct polarity is observed.
