Assembly Instructions & General Information
1Mechanical: The Backplanes are intended for horizontal assembly.
2Mounting: Attach the Backplane, using at least every second mounting hole at the top
and the bottom, with M2.5 screws and isolating washers.
Note: Do not tighten the screws.
Align the Backplane by inserting Boards in the outer guide rails at the left and the right and
tighten all screws.
Note: We recommend to use the Schroff mounting kit, see catalog or at www.schroff.biz.
3Chassis GND: If noise reduction shall be achieved by connecting digital GND to Chassis
GND, use conductive washers instead of isolating washers. Spring washers are recom-
mended instead of flat washers. Creepage and clearance between screw and GND are in
accordance with EN60950.
4V(I/O): Check V(I/O) coding and V(I/O) power bridge. The default assembly is +5 V (blue
key at connector P1 and power bridge between V(I/O) and +5 V). To set V(I/O) to 3,3 V,
change the keys and set the power bridge between V(I/O) and 3,3 V.
(Conversion kit, order# 21101-658, including 8 yellow keys and tool)
5Power input: The Backplane provide 47-position connectors to connect CPCI plug-in
power supplies. The AC power is brought to the 47-position connectors by “feed through”
contacts.
6Power output: The Backplane provide power bugs to connect power output cables. M4
cable lugs should be used to connect the power output cables to the power bugs.
Maximum 2 cables are allowed per power bug. Please assemble the cable lugs with the
flat side to the power bug to ensure the correct isolation distance between the not insu-
lated part of the power cable and not insulated parts of the backplane.
