3.6 Installation of a wall-mounted frequency converter
3.6.1 Suitable installation location for wall mounting
Make sure that the installation location for wall mounting a VAU meets the following conditions:
The frequency converter must be mounted on a firm level surface.
The frequency converter may only be mounted on non-flammable surfaces.
There must be clearance of 200 mm around the frequency converter to ensure free convection.
The figure below shows the assembly dimensions and the required clearances for installing the frequency
converter.
Fig. 17:
For the "wall mounting" version, the cable length between the motor and VAU must not exceed 5 m. Only
use a shielded cable with the required cross section. A PE connection (below terminal board of the wall
adapter) must be established.
3.6.2 Mechanical installation
1. Open the motor connection box.

IMPORTANT INFORMATION
The cable gland provides strain relief, and the PE connection cable must be connected in a leading
fashion (considerably longer)!
2. Use suitable EMC glands to connect the shielded motor cable to the motor connection box!
Ensure that the shielding has sound (large area) contact!
3. Connect the prescribed PE connection in the motor connection box!
4. Close the motor connection box.
