Compatibility (EMC)
12-1General
In accordance with the provisions described in
the European Commission Guidelines Document
on Council Directive 89/336/EEC,IMO Precision
Control Ltd. have chosen to classify the VXSM
range of inverters as "Complex Components".
Classification as "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 VXSM
inverters and to his customer or the installer and
the user.
Jaguar VXSM 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
Immunity : Second environment
(Industrial environment )
Emission : First environment (Domestic
environment )
Finally, it is customer’s responsibility to
check whether the equipment conforms to
EMC directive.
12-2 Recommended Installation
Instructions
For conformance with the EMC Directive,
these instructions must be followed.
Follow the usual safety 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 12-
2-1.
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 screened cable for control, motor and
other main wiring which is connected to the
inverter, and these screens should be
securely earthed (at both ends in case of
motor cable).
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. "
