4.9.3 EMC filter information
Refer to Figure 4-1 on page 33 for the location of the optional EMC filter. See Table 4-20 for EMC filters that can be sourced directly from Epcos and
Schaffner.
Table 4-20 Mentor MP and EMC filter cross references
* This filter is required if the input current to the Mentor MP will be greater than 66 Amperes.

(shown in decreasing order of permitted emission level):
C4
EN 61800-3 second environment, restricted distribution
(Additional measures may be required to prevent interference)
C3
EN 61800-3 second environment, unrestricted distribution
C2
Industrial generic standard EN 50081-2 (EN 61000-6-4)
EN 61800-3 first environment restricted distribution (The
following caution is required by EN 61800-3)
C1
Residential generic standard EN 50081-1 (EN 61000-6-3)
EN 61800-3 first environment unrestricted distribution
EN 61800-3 defines the following:
•
The first environment is one that includes residential premises. It
also includes establishments directly connected without intermediate
transformers to a low-voltage power supply network which supplies
buildings used for residential purposes.
•
The second environment is one that includes all establishments
other than those directly connected to a low-voltage power supply
network which supplies buildings used for residential purposes.
•
Restricted distribution is defined as a mode of sales distribution in
which the manufacturer restricts the supply of equipment to
suppliers, customers or users who separately or jointly have
technical competence in the EMC requirements of the application of
drives.
4.9.4 Surge immunity of control circuits - long
cables and connections outside a building
The input/output ports for the control circuits are designed for general
use within machines and small systems without any special precautions.
In applications where they may be exposed to high-energy voltage
surges, some special measures may be required to prevent malfunction
or damage. Surges may be caused by lightning or severe power faults in
association with grounding arrangements which permit high transient
voltages between nominally grounded points. This is a particular risk
where the circuits extend outside the protection of a building.
As a general rule, if the circuits are to pass outside the building where
the drive is located, or if cable runs within a building exceed 30m, some
additional precautions are advisable. One of the following techniques
should be used:
1. Galvanic isolation, i.e. do not connect the control 0V terminal to
ground. Avoid loops in the control wiring, i.e. ensure every control
wire is accompanied by its return (0V) wire.
2. Shielded cable with additional power ground bonding. The cable
shield may be connected to ground at both ends, but in addition the
It is essential that line reactors be connected between the
filter terminals and the power input terminals, as shown in
Figure 4-1. Failure to observe this requirement could result in
destruction of the thyristors.
