NOTICE
Damage to the mounting aid when lifting without a shackle
The HF Choke Module can be damaged if the crane hook is directly attached to the lifting eyes
of the mounting aid.
• Always use a shackle to lift the HF Choke Module.
Mounting plate
When installing the High Frequency Drive in a control cabinet, use a mounting plate with the
following properties:
• Material: Aluminum
• Thickness: 15 mm
• Surface roughness: Rz25
Note
The mounting plate must be connected to the protective conductor connection of the control
cabinet through a low impedance. See also Chapter "Protective connections and equipotential
bonding (Page 178)".
Heat dissipation
It is not necessary to install a separate cold plate cooling to cool the HF Choke Module and
HF Damping Module. The modules are cooled through the mounting plate. The mounting plate
cooling assumes the internal cooling circuit in the cold plate of the HF Motor Module.
Drilling patterns
The drilling patterns shown below apply to the High Frequency drive with and without Active
Line Module, booksize format.
Prepare the mounting plate as follows:
1. Machine the M6 threaded holes.
2. Countersink the holes with ∅ 18
