EMC (Electromagnetic compatibility)

The requirements for EMC are divided into three levels in the following
three sections:
Section 4.10.3, General requirements for all applications, to ensure
reliable operation of the drive and minimise the risk of disturbing nearby
equipment. The immunity standards specified in Chapter 11 Technical
data on page 159 will be met, but no specific emission standards are
applied. Note also the special requirements given in Surge immunity of
control circuits - long cables and connections outside a building on
page 68 for increased surge immunity of control circuits where control
wiring is extended.
Section 4.8.4, Requirements for meeting the EMC standard for
power drive systems, IEC61800-3 (EN 61800-3:2004).
Section 4.8.5, Requirements for meeting the generic emission
standards for the industrial environment, IEC61000-6-4, EN 61000-6-
4:2007.
The recommendations of section 4.8.3 General requirements for EMC
on page 65 will usually be sufficient to avoid causing disturbance to
adjacent equipment of industrial quality. If particularly sensitive
equipment is to be used nearby, or in a non-industrial environment, then
the recommendations of section 4.8.4 or section 4.8.5 should be
followed to give reduced radio-frequency emission.
In order to ensure the installation meets the various emission standards
described in:
• The EMC data sheet available from the supplier of the drive
• The Declaration of Conformity at the front of this manual
• Chapter 11 Technical data on page 159
The correct external EMC filter must be used and all of the guidelines in
section 4.8.3 General requirements for EMC on page 65 and section
4.8.5 Compliance with generic emission standards on page 66 must be
followed.

High ground leakage current
When an EMC filter is used, a permanent fixed ground
connection must be provided which does not pass through a
connector or flexible power cord. This includes the internal
WARNING EMC filter.

NOTE
The installer of the drive is responsible for ensuring compliance with the
EMC regulations that apply in the country in which the drive is to be
used.
4.8.1 Grounding hardware
The drive is supplied with a grounding bracket / clamp to facilitate EMC
compliance. This provides a convenient method for direct grounding of
cable shields without the use of "pig-tails". Cable shields can be bared
and clamped to the grounding bracket using metal clips or clamps
supplied) or cable ties. Note that the shield must in all cases be
continued through the clamp to the intended terminal on the drive, in
accordance with the connection details for the specific signal.

A suitable clamp is the Phoenix DIN rail mounted SK14 cable clamp
(for cables with a maximum outer diameter of 14 mm).

See Figure 4-17 for details regarding the installation of the grounding bracket.
Figure 4-17 Installation of grounding bracket (size 1 to 4)
Loosen the ground connection screws and slide the grounding bracket in
the direction shown. Once in place, the ground connection screws
should be tightened to a maximum torque of 1.5 N m (1.1 lb ft).

Loosen the ground connection nuts and slide the grounding bracket in
the direction shown. Once in place, the ground connection nuts should
be tightened to a maximum torque of 2.0 N m (1.47 lb ft).
