2.6.3.2 Installation with Long Motor Cable
Warning
Risk of electrical shock!
All motor wires will carry high voltages when the controller is powered.
In applications where the motor cable is not long enough, the motor cable can be extended
under the following conditions (see Figure ):
1. Use optional metal junction box mounted directly to the motor shaft (therefore the fan
has to be ordered with the available junction box option).
2. Keep the motor cable as short as possible,
up to 5 m maximum
.
3. Use
shielded
cables.
4. Fan and controller should both be mounted on the same electrical conducting wall or
chassis (ground plane).
5. Keep all cables close to the fan or ground plane.
6. Motor cable should be separated from other cables (mains supply, control) to prevent
EMI from cross-talking between motor cable and the other cables.
7. Do not run motor cable in parallel to other cables, these cables should cross under
right angle.
