Chapter 6 EMC Instruction
6-1 Installation environment
Table 6-1 shows the EMC standard conformity table of VAT300. VAT300 supports EN61800-3
Second Environment Category C3 by using either built in or external filters.
However First environment Category C2, is achieved only for drives
X000K7 to X005K5,
Refer to Tables 6-2 and 6-3 for the EMI filter and ferrite core to apply.

Installation into a metal cabinet
To clear the levels of the Residential, Commercial, Light Industrial Environments and the Industrial
Environment for the drives up to 475kW, the following method of installation is required.
6-2-1 When using drives with built-in EMI filters (N000K7 to N005K5, X000K7 to X030K0)
(1) Install the drive with built-in filters in a metal cabinet. This ensure to meet Second Environment
Category C3.
Note that drives from N000K7 to N002K2 and from X000K7 to X005K5, can meet First
environment Category C2, by installing 3 pieces of the ferrite cores on the power source cable,
one on the motor cable and other on the control cable as shown in Fig. 6-1.
All these 5 ferrites are delivered into the drive package, when order VAT300 with built-in filter.
(2) The power source cable and motor cable outside the metal cabinet should be shielded and made
to be as short as possible. Electrically connect the shield to the earth terminal of the motor.
(3) In order to suppress the noise emission from the cables, earth the shield of the power source
cable and motor cable to the metal cabinet with metal clamps.
(4) Use the shielded cables for the drive control wiring and earth the shield to the metal cabinet with a
metal clamp
6-2-2 When using the external EMI filters (VAT300-N007K5 to N045K0, X037K0 to X475K0)
(1) Install the drive unit in a metal cabinet and put the EMI filter on the power source cable as shown
in Fig. 6-2.
(2) The power source cable and motor cable outside the metal cabinet should be shielded and as
shortest as possible. Electrically connect the shield to the earth terminal of the motor.
(3) It is not necessary to use shielded cables for the control circuit wiring inside the metal cabinet.
However, make the EMI filter power source cable and the motor cable as short as possible, and
separate them as far from each other as possible.
(4) In order to suppress the noise emission from the cables, earth the shield of the power source
cable and motor cable to the metal cabinet with metal clamps.
(5) Use the shielded cables for the drive control wiring and earth the shield to the metal cabinet with a
metal clamp.
