MD_60A Operating Instructions
Installation instructions for basic unit
Input filter
•
Sizes 1 and 2 are fitted with an input filter as standard. This input filter ensures that
limit value class A is maintained on the supply side. Use an NF...-... input 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 input filter close to the inverter, but outside the minimum clearance area
for cooling.
•
Restrict the cable between the input filter and the inverter to the absolute
minimum length required, and never more than 400 mm (15.8 in). Unshielded,
twisted cables are sufficient. Also use unshielded cables for the supply system lead.
•
This input filter must be mounted either directly at the entry point into the switch
cabinet or in the immediate vicinity of the inverter if several inverters are
connected to the same input filter. The input filter must be chosen on the basis of
the total current of the connected inverters.
•
No EMC limits are specified for interference emission in voltage supply
systems without an earthed star point (IT systems). The effectiveness of input
filters in IT systems is severely limited.
Interference
emission
SEW recommends the following EMC measures on the motor side to maintain the
class A and B limits:
•
Shielded motor cable
•
HD... output choke option
HD... output choke
•
Install the output choke close to the inverter, but outside the minimum clearance
for cooling.
•
Route all three phases together through the output choke. Do not route the PE
conductor through the output choke!
