Vacon NXS0261-2A2H0SSF [10/12] Emc and installation environment

EMC and installation environment

The product family standard EN/IEC 61800-3 + A1 sets limits for both emissions and

immunity of radio frequency disturbances. The environment has been divided into the

and 2

environments, i.e. in practice, the public and industrial networks, respectively.

Radio Frequency Interference (RFI) filters

are typically required to meet the EN/

IEC 61800-3 + A1 standard. These filters

are integrated in the VACON® NXS as

standard.

The 208–240 V and 380–500 V ranges of

the VACON® NXS (FR4-FR9) fulfills the

requirements of the 1st and 2nd

environments (H level: EN/IEC 61800-3

+ A1, category C2). No additional RFI

filters or cabinets are required. The

FR10-FR11 and the 500-690 V range of

the VACON® NXS fulfills the require-

ments of the 2nd environment (L-level:

EN/IEC 61800-3 + A1, category C3).

The units in the enclosure sizes of FR4,

FR5 and FR6 (the voltage range from

380 to 500 V) are also available with

extremely low-emission integrated EMC

filters (C level: EN/IEC 61800-3 + A1,

category C1). This is sometimes required

in very sensitive locations such as

hospitals.
