HD output choke
•
Install the output choke close to MOVITRAC
®
B
outside the minimum clearance
.
•
Always route all three phases (
not PE
) together through the output choke.
•
If the cable is shielded, do
not
route the shield through the output choke.
When using the
HD
output choke, the cable must be
wrapped around the choke
5 times
.
Only 5 loops are possible if the cable has a large diam-
eter. To make up for this, 2 or 3 output chokes should be
connected in series. SEW recommends connecting in
series 2 output chokes in case of 4 windings and 3
output chokes in case of 3 windings.
•
Installing HD012 output choke:
Install output choke under the corresponding inverter. Leave a ventilation space of at
least 100 mm (3.94 in) below and above the output choke. Provide a clearance of
10 mm (0.39 in) on each side.
Three alternative connection options are provided for connecting the protective
earth. You can connect the PE line of the motor cable directly on the frequency
inverter.
