24 en | Install the MIC (standard) PSU
Notice!
You must connect the overall shield drain wire of the composite cable to the power supply
chassis in order to ground the chassis. Crimp the drain wire to the ring terminal lug attached
to the mounting screw of the PCB located to the right of BNC socket CN3 (Video Switched).
Refer to Layout of MIC-240PSU-2 and MIC-115PSU-2, page 17 for the location of the screw.
19. Slide back the cable so that the shield is in the middle of the gland.
20. Tighten the cable gland so that it grips firmly the shielded composite cable. It is important
that the braided cable screen engages with the internal clamps of the cable gland to ensure
correct EMC protection.
21. If necessary, connect a tamper switch to terminal block HD2.
22. Make the necessary video connections. Feed the coaxial cable of your choice--see the table
below to identify the recommended cable types, maximum distance, and other specifications
for the coax video connection between the MIC power supply and the head-end control
system--through the top-left M12 cable gland (item 1 in the figure "MIC PSU Enclosure, with
cable glands identified").

23. Crimp the end of the cable with a BNC terminal connector.
24. Connect the Video Out cable to BNC socket CN1.
For dual video output only: If needed, remove the blanking plug that covers the hole for the
bottom-left M12 cable gland (item 3 in the figure "MIC PSU Enclosure, with cable glands
identified"). Feed a second Video Out cable through the cable gland, and then connect the
switched Video Out cable to BNC socket CN3. This second cable provides control for video
from both the optical camera and the thermal camera; users can switch between the two
cameras.
25. Feed telemetry cable through the bottom-right M12 cable gland (item 4 in the figure "MIC
PSU Enclosure, with cable glands identified").
26. Connect head-end RS-485 control to terminal block HD5, as indicated in the table below:

Note: The terminal block is positioned with the screw terminals on the left, next to the fuses.
Pins are numbered from top to bottom in that orientation. Non-IR PSU PCBs are marked.
