Check the power supply’s polarity before connecting it to the MLC.
If you choose to power the MLC from a separate external power supply rather
than from a MLS 306/506/506 MA/506 SA or MLS 100 Series switcher, you
must connect a ground wire between the MLS and the MLC, as shown in the
following diagrams.
