Table 60: The equivalents of the product standard IEC/EN 61800-3 + A1 in Vacon classes
EMC category in the product
standard IEC/EN 61800-3 + A1
C1
C2
C3
C4
No EMC emission protection.
The category changes when these properties in the AC drive change:
the level of electromagnetic disturbances
•
the requirements of a power system network
•
the installation environment (see 9.3.1 Environment definitions in product standard IEC/EN
•
61800-3 + A1).
The Type designation code tells which category requirement your AC drive obeys.
All Vacon NX AC drives obey all EMC immunity requirements (standard IEC/EN 61800-3 +
A1).
CATEGORY C1
Available for 380-500 V, FR4 to FR6, IP54 (UL Type 12).
The AC drives in category C1 have the best EMC protection. These AC drives have the
nominal voltage of less than 1000 V. They are used in the 1st environment.
NOTE!
If the protection class of the AC drive is IP21 (UL Type 1), only the conducted
emissions are in the requirements of category C1.
CATEGORY C2
Available for 380-500 V, FR4 to FR9 and 208-240 V, FR4 to FR9.
The category C2 includes AC drives in fixed installations. These AC drives have the nominal
voltage of less than 1000 V. The category C2 AC drives can be used in the 1st and the 2nd
environment.
CATEGORY C3
Available for IP21 (UL Type 1) and IP54 (UL Type 12) in 380-500 V FR10 and larger, 500-690 V
FR6 and larger.
