Filter placement:
1. Set screws loose into wall, leave 5mm distance from head to wall.
2. Lift filter with appropriate crane, smallest types (up to 25kg) may be lifted
manually by two persons.
3. Place filter first onto lower screws…
4. ...then position it through backplane head openings on upper screws.
5. Fix screws with appropriate torque (depending upon the material of the
back plane and local standards).
Step 3: Wiring
1)
Verify safe disconnection of all line side power.
Consult your local safety instructions.
2)
Carefully connect protective earth (PE) wire to adequate earth potential close to HFS
harmonic filter.
Use a wire diameter of equal or bigger size as foreseen for line/load side power cables
– according
to your local codes and safety instructions.
3)
Connect PE wire of HFS harmonic filter
with appropriate cable lug to threaded stud.

4)
Connect harmonic filter
load side terminals L1’, L2’, L3’ to respective motor drive inputs.
See below table for the recommended wire size and torque. Use stranded copper wire with a temperature rating
of 75°C or higher.

Note. ** It is recommended to use cable lugs when wiring.
An optional workflow to connect power terminals without having the TDJ module in way is applied. You
might consider following these steps:
Connecting power terminals of passive harmonic filters ordered with TDJ module can be facilitated by removing
the trap disconnect wires while connecting the cables to the main terminals. Afterwards the trap disconnect
jumper cables need to be applied to the original position again. Please follow these steps: Open terminals D1-
D1’, D2- D2’and D3- D3’, remove the wires, add main terminals and then fix wires on terminals D1- D1’, D2-
D2’and D3- D3’ again. The recommended torques given on the terminal label must be applied.
Remarks regarding IP 20 enclosure
▪
To connect HFS harmonic filter line and load side terminals, the finger guard has to be removed as a
first step, and be installed again when the line and load side terminals are connected. The screw thread
and torque value for all the frame sizes are:
|
Screw thread: M5
|
Screw torque value: 4Nm
▪
The metal finger guard for frame sizes E, F and G are equipped with
grommets, whilst finger guard H is equipped with stepped collars. Modify the
stepped collars according to the cable isolated diameter, 5-10mm margin is
recommended to feed the cable easier.
