Proceed as follows to mechanically install the frequency converter:
1. Fit the seal (3).
2. Screw the adapter plate (1) on to the motor with the four fastening bolts (10) and four spring ele-
ments (torque: M4 to 2.4 Nm, M5 to 5.0 Nm, M6 to 8.5 Nm).

IMPORTANT INFORMATION
When mounting the adapter plate (1), ensure that all four fastening bolts (10), including the spring
elements, are tightened to the appropriate torque!
All contact points must be free of dirt/paint, otherwise a correct protective conductor connection
cannot be ensured!
3. Attach the original junction plate (8) to the motor, using the optional terminal board height adjust-
ment (7) and the optional extended bolts (9) if necessary.
4. Connect the four cables (PE, U, V, W) with the corresponding cross section (depending on the
rating of the VAU in use) to the original terminal board (8).

IMPORTANT INFORMATION
The connecting cables (approx. 30 cm) needed for the wiring of the motor terminal board/VAU are
not included in the scope of delivery!
Please ensure that the seal (3) sits perfectly!
5. Screw the support (6) to the adapter plate (1) with four fastening bolts (4) incl. the spring elements
(torque: 5.0 Nm).
6. Feed the four cables (PE, U, V, W) through the VAUS support.

IMPORTANT INFORMATION
Please ensure that the O-ring seal (5) sits perfectly!
7. Carefully plug the frequency converter onto the support (6) and secure it evenly with two M8 bolts
(11) (torque: max. 25.0 Nm).
