Up to 11 kW, MOVITRAC

B frequency inverters have an integrated line filter as stan-
dard. They comply with the following limit value class to EN 61800-3 on the line side
without further measures:
• 1-phase connection: C1 cable conducted
• 3-phase connection: C2
No EMC limits are specified for interference emission in voltage supply systems without
an earthed star point (IT system). The efficiency of line filters is severely limited.

ULF11A folding ferrites
Place the supply system cable (L and N) in the folding ferrite and press the folding fer-
rites together until they snap in place.
Compliance with EMC limit class C1 has been tested on a specified test setup. Compli-
ance with class C1 for signal interference is achieved by the proper installation of
ULF11A folding ferrites.
4.4.7
HF output filters
• Limit the length of the cable between inverter and output filter to the absolute mini-
mum needed. Maximum 1 m / 3 ft with unshielded cable, 10 m / 33 ft with shielded
cable.
• Several motors can be connected to one output filter when operating a motor group
from one inverter. The total value of the rated motor currents must not exceed the
nominal throughput current of the output filter.
• Two identical output filters can be connected in parallel to one inverter output to dou-
ble the nominal throughput current. To do this, connect all like connections to the out-
put filters in parallel.
• Output filter connection V5 (with HF..-503) or 7 (with HF..-403) must not be con-
nected when the inverter is operated with f
PWM
= 4 or 8 kHz.
• No V
DC link
connection is permitted for size 0XS units.
HF output filter connection without V
DC link
connection (PWM frequency only 4 or 8 kHz)
INFORMATION
Install output filters next to the corresponding inverter. Leave a ventilation space of at
least 100 mm (3.94 in) below and above the output filter. No clearance is required on
the sides.
