Surface-Mounted Devices (SMDs) are used in the production of

SM-ACI1 modules. The components to be changed, marked

with an asterisk in figure 4-5, need not necessarily be SMDs.

Please, refer to the board overview figure (solder side, figure 4-

3) for the approximate position of the jumpers. Notice should be

taken of the fact, that when calculating component values for a

specific filter, the capacitor/resistor relationship is almost linear.

For this purpose, it is suggested that only the capacitor be

changed. Hence, for a doubling of the filter frequency input, the

value of the capacitor should be reduced by half.

4.4.7Screw Terminal Pinouts

In the following, the pinout/signal relationship for the SM-ACI1,

when connected to a particular screw terminal block, is shown.

Figure 4-6: Screw Terminal Pinout

WARNING!

Dangerous voltages are present at the terminals.
