Installation instructions for the basic unit
Installation
Line filter
•
Sizes 1 and 2 are fitted with a line filter as standard. This line filter ensures that
limit value class A is maintained on the supply side. Use an NF...-... line filter as
an option to maintain the class B limit.
•
The NF...-... input filter option is required for sizes 3 to 5 to maintain class A and
B limits.
•
Install the line filter close to the inverter but outside the minimum clearance for
cooling.
•
Do not switch between the line filter and MOVIDRIVE
®
.
•
Keep the length of the cable between the line filter and inverter to an absolute
minimum, and never more than 400 mm. Unshielded, twisted cables are sufficient.
Use also unshielded lines for the supply system lead.
•
This line filter must be mounted either directly at the entry point into the switch
cabinet or close to the inverter if several inverters are connected to the same
line filter. The lime filter must be chosen on the basis of the total current of the con-
nected inverters.
•
No EMC limits are specified for interference emission in voltage supply sys-
tems without grounded star point (IT systems). The effectiveness of input filters
in IT systems is severely limited.
Interference
emission
SEW-EURODRIVE recommends the following EMC measures on the output side to
maintain the class A and B limits:
•
Shielded motor cable
•
HD... output choke option
NOTE
•
This is a product with restricted availability in accordance with IEC 61800-3. It may
cause interference in residential environments. In this case, the operator may need
to implement appropriate measures.
