3.7 CSG14H and P Series, DC-powered, -48VDC, 24VDC and 12VDC Installation
This section describes the proper connection of the -48VDC leads (or 24VDC,
12VDC leads) to the DC power terminal block on
the Magnum CSG14H hardened media converter
(as shown in Figure) . The DC terminal block on
the Magnum CSG14H is located on the left side of
the unit and is equipped with three (3) screw-down
lead posts. The power terminals are identified as
positive (+) and negative (-), and they are floating
inside the unit so that the user if desired may
ground either of the terminals. The chassis is “earth” or ground (GND).
