Step Action Comment
1
Mark out the positions of the tapped
holes and the breakthrough on the
backing plate.
Cut a tap for each fixing screw in the
backing plate and cut out the
breakthrough.
Dimensional drawings/hole
spacing see Table 2.5.
The tapping area will provide you
with good, full-area contact.
2
Mount the drive controller for high-speed
drives vertically on the backing plate.
Tighten all screws to the same tightness.
Pay attention to the mounting
clearances! The mounting seal
must contact flush on the surface.
3
Mount the other components, such as the
mains filter, line choke etc., on the
backing plate.
Mains filter max. 20 cm below the
drive controller for highspeed
drives

Continue with electrical installation in
section 3.
Note the following points:
• Distribution of power loss:
• The all-round mounting collar must be fitted with a seal. The seal
must fit flush on the surface and must not be damaged.
(1) Seal
(2) Tapped hole for
EMC contact
(3) Outside
(4) Inside
• The backing plate must be well grounded.
• The best result for effective EMC installation is attained with a
chromated or galvanized backing plate. If backing plates are
varnished, the coating must be removed in the area of the contact
surface!
