Answer Drives 1000

Networks with asymmetric ground connection
(defined in the table below)
In these applications, the internal RFI filter must be disconnected.
If the ground configuration of the power supply network is unknown,
disconnect the internal RFI filter.
5.9.3 COMPLIANCE OF AD1000 TO IEC 61800-3
The AD1000, with RFI filter, comply with the requirements defined in EN
61800-3 for the second environment category C3 and C4.
The AD1000, with optional filter class B, also meet the narrow limits of the
first environment category C2 with motor cable lengths less than 25 meters.
CAUTION!:
“This is a product of category C2 according to IEC 61800-3.
In a domestic environment this product may cause radio interference in
which case additional measures may be required to reduce interference.
The installation warnings and recommendations in this manual must be
observed.
To limit emissions the AD1000 units are provided with EMC filter (installed
inside or outside of the drive according to its size).
Optional RFI filters are available for using the drive in the first environment.
NOTE
a) If the drive is installed on a floating network (IT), the standard EMC
filter must be disconnected. The network should be connected to
ground potential through the EMC filter capacitors with consequent
possible damage to the unit. EMC filters suitable for IT network are
available on request.
b) Refer to paragraph 5.4 for connecting the RFI filter to the drive.
c) The codes of the RFI filters are shown in Table 5.5.1.
NOTE
If the above mentioned provisions cannot be observed, (e.g. the drive
cannot be equipped with EMC filter as it is installed on a floating network
(IT)), the requirements of the EMC Directive for restricted distribution can
be met as follows:
1. Make sure that no excessive emission is generated to neighbouring low
voltage power supply network. In some cases, the natural suppression in
transformers and cables is sufficient. When in doubt, use a transformer
with a screen between primary and secondary.
2. An EMC plan for preventing disturbance has been defined for
this particular installation.
3. Power and control cables have been provided as required in
this Manual.
4. The drive is installed according to the instructions in the manual.
