MIC Power Supply Units (PSUs) for IR MIC Cameras
The figure below displays the layout of the PCB in the MIC PSUs for IR cameras, with call-out
numbers to the side of or below the connection/terminal ID or the terminal, and ’on’ the
fuses. The table below the figure identifies the connections.

Earth Link on the PCB
The printed circuit board (PCB) of each MIC PSU (IR and non-IR) has one Earth Link option,
near terminal block HD1, to allow the PSU to be set up for different earthing schemes:
–
If there is a separate connection between video screen and earth, the Earth Link should
be broken. This usually occurs on copper-connected systems where all of the copper
video coaxes are taken back to the control room to be connected to a central earth point.
–
If fiber optics or other indirect connections are used to get data and video to and from
the control room, then the Earth Link should be left intact, as long as it is the only
camera-end earth reference point.
