Appendix D: Compliance; Emc Connections - Parker 890 Quick Start Manual

Appendix D: Compliance

A comprehensive guide to product compliance is available in the full product manual.
Warning Where there is a conflict between EMC and safety requirements personnel safety shall
always take precedence.
Operation of this equipment requires detailed installation and operation instructions provided in the
installation/operation manual intended for use on this product.
Caution: This is a product of the restricted sales distribution class according to IEC 61800-3. It is
designated as "professional equipment" as defined in EN61000-3. Permission of the supply authority
shall be obtained before connection to the low voltage supply.
In a domestic environment this product may cause radio interference in which case supplementary
mitigation measures may be required.
This equipment contains electrostatic discharge (ESD) sensitive parts. Observe static control
precautions when handling, installing and servicing this product.
EMC Emissions
Conducted Emissions comply with EN61800-3 category C3 when installed in accordance with
instructions in Chapter 4 / 5 refer to "mounting the unit".
Radiated Emissions comply with EN61800-3 category C3 when fitted with specified external filter.
Immunity complies with the requirement of EN61800-3, for equipment intended for use in the second
environment.

EMC Connections

For compliance with the EMC requirements, the "0V/signal ground" is to be separately earthed. When
a number of units are used in a system, these terminals should be connected together at a single,
local earthing point.
Control and signal connections should be made with screened cables, with the screen connected only
at the VSD end. However, if high frequency noise is still a problem, earth screen at the non VSD end
via a 0.1μF capacitor.
Note: Connect the control and signal screens (at the VSD end) to the VSD protective earth point, and
not to the control board terminals.
Motor cables should have a 360° bond to ensure a low impedance connection, as per the figure
below;
