3. An EMC plan for preventing disturbances is drawn up for the installation. A
template is available from the local ABB representative.
4. The motor and control cables are selected as specified in the Hardware Manual
5. The drive is installed according to the instructions given in the Hardware Manual.
Notes
Note 1: It is recommended to equip the ACx 607/627 with EMC filtering if equipment
sensitive to conducted emission is connected to the same supply transformer as the
drive.
Note 2: The ACx 677 must not be equipped with EMC filtering.
Note 3: The drive must not be equipped with EMC filtering (refer to Table A-1) when
installed to IT (unearthed) networks. The mains becomes connected to earth potential
through the EMC filter capacitors. In IT networks, this may cause danger or damage
the unit.
Table A-1
The EMC filtering of the drives is marked in the type code as follows. 1 =
EMC cabinet, 2 = EMC cabinet with EMC filters.
ACS 600 Type
The drives comply with the European Union Machinery Directive (98/37/EC)
requirements for an equipment intended to be incorporated into machinery.
