Filters FN3471/73/81/83 in frame size S08 and L08 offer two possi-
bilities of fixation points.
The preferred fixation points have a distance S1 between the
screws on the terminal side and screws on the capacitor side as
shown in Figure 25.
Other permitted fixation points are offered in case of difficult acces-
sibility of the rear fixation points. Those permitted fixation points
have a distance S2 between the screws on the terminal side and
screws on the capacitor side as shown in Figure 26.
Warning: In all cases, the usage of the two fixation
screws on terminal side (right side on Figure 24, Figure 25 and
Figure 26) is mandatory. The usage of shorter distance than S2
between fixation points and usage of less than 4 fixation
screws is forbidden and could result in damage to the product
and serious injuries.
