ACA 635 IGBT Supply Sections
Use of the ACx 600 in Second Environment without EMC filtering (EN 61800-3: second
environment includes all establishments other than those directly connected to a low-
voltage power supply network which supplies buildings used for domestic purposes.)
Unearthed Mains
(IT Network)
1. It is ensured that no excessive emission is propagated to neighbouring low-
voltage networks. In some cases, the natural suppression in transformers and
cables is sufficient. If in doubt, the supply transformer with static screening
between the primary and secondary windings can be used.
2. The ACS 600 MultiDrive is installed according to the instructions given in the
Hardware Manual
(EN code 63700118).
3. The motor and control cables are selected as specified in the
Hardware Manual
(EN code 63700118).
4.
Note:
The ACS 600 MultiDrive must not be equipped with EMC filtering when
installed to floating networks. The mains becomes connected to earth potential
through the EMC filter capacitors. In floating networks this may cause danger or
damage the unit.
Machinery Directive
ACS 600 MultiDrive frequency converters comply with the European Union Machinery
Directive (89/392/EEC) requirements for an equipment intended to be incorporated into
machinery.
