compatibility (EMC)
11-1 General
In accordance with the provisions described in
the European Commission Guidelines
Document on Council Directive 89/336/EEC,
IMO has chosen to classify the Jaguar VXM
range of Inverters as “Complex Components.
Classification as a “Complex Components”
allows a product to be treated as an
“apparatus”, and thus permits compliance with
the essential requirements of the EMC Directive
to be demonstrated to both an integrator of
Jaguar Inverters and to his customer or the
installer and the user.
Jaguar Inverters are supplied ‘CE-marked’,
signifying compliance with EC Directive
89/336/EEC when fitted with specified filter units
installed and earthed in accordance with this
sheet.
This Specification requires the following
performance criteria to be met.
EMC product standard EN61800-3:1997
+A11:2000
Immunity: Second environment (Industrial
environment)
Emission: See tables 1 and 2
11-2 Recommended
Installation Instructions
It is necessary that to conform to EMC Directive,
these instructions must be followed.
Follow the usual safely procedures when
working with electrical equipment. All electrical
connections to the filter, Inverter and motor must
be made by a qualified electrical technician.
1) Use the correct filter according to Table
11-1.
2) Install the Inverter and filter in the electrically
shielded metal wiring cabinet.
3) The back panel of the wiring cabinet of board
should be prepared for the mounting
dimensions of the filter. Care should be taken to
remove any paint etc. from the mounting holes
and face area of the panel. This will ensure the
best possible earthing of the filter.
4) Use the screened cable for the control, motor
and other main wiring which are connected to
the Inverter, and these screens should be
securely earthed.
5) It is important that all wire lengths are kept as
short as possible and that incoming mains and
outgoing motor cables are kept well separated.
To minimize the conducted radio disturbance in
the power distribution system, the length of the
motor cable should be as short as possible.
Finally, it is the customer’s responsibility to
check whether the equipment conforms to
EMC directive.
