Obviously, the directive does not point out in detail neither the criterions which have to be applied in order to
judge a device EM-compatible, nor the actions that have to be taken, in order to keep it in that way. That task is
up to the Product Standard concerned with the product; if this would not exist or if the part concerning EMC had
been missed, the product manufacturer must refer to the Generic Standard.
Therefore, being EMC conformant, does not mean high-immunity and low-emissions, but it implies the
adherence to the limits imposed by a product standard, which cannot foresee any limitation.
Seeing the wide range of products to which the directive refers and its legal nature, it became necessary for the
manufacturers of products of the same typology, to give an interpretation of the directive, with no official value,
but whose validity is linked with the acknowledgment of the association of some categories. (The only document
recognized by CE is the directive).

In this standard it has been assigned the noise-levels to which the equipment must be submitted under the
immunity test and the allowed emission limits.
On the whole the machine manufacturer, or GE customers, belong to the validity field CEMEP number 4 as
“System /apparatus” and therefore they have the obligation of CE Mark and Declaration of Conformity.
The machine manufacturer has the responsability of EMC conformity. They have the right to receive all the
necessary indications (filter, installation, etc.) in order to comply with EMC standard from the single component
producers.
Almost all the products do not have product standard as far as EMC concerns and they have to refer to the
generic standards, which are EN50081-1 and 50081-2 as far as emissions in residential and industrial environments
and
EN50082-1
These documents, as far as the radio-frequency emissions concern, refer to the specific standard EN55011
which define the emissions limits in industrial environment (class A limits) and residential (class B limits).
This is why, despite the less restrictive limitation imposed by the product standard

technical support service. In case of Restricted Distribution the limits are equal to the class A ones of
Standard EN5501 1, while in case of Unrestricted Distribution equal to class B for devices with rated current
less than 25A and class A for higher current.
Regarding the second Environment (A), which is the most frequently notable case, the limits are not defined
yet. As already anticipated in the conclusion at the first section, it is to refer to the limits, defined by the
curves A-B of standard EN5501 1.
In general, to have GE equipment in its limits, whether class A or B, it would be necessary both additional
devices (filters) and the respect of strict installation rules: in the next two paragraphs it will be given either

ECF filters are needed for

motor cable length less then 20 m for 3015 device size and higher
-

Applications that require long motor cable length (greater than 20 m) or residential installation environment,
will be satisfied by the FN, Compact, Ranger or S-.... filters.
The EFC filters are parallel connected on the supply line of the device.
The some kind of filter can be used for both converter and inverter. For multi-drive applications, it is enough to
use only one filter, which should be connected to the incoming line before all mains chokes, sized for the total
power rating of all units fed.
ECF filters are connected before the main choke.

SHIELD OF CABLES FOR ANALOG SIGNALS
The cables of analog signals must be shielded (each signal must be contained in the shield connected to the zero
volt terminal), the same is valid for the constant references (E.g..
converters the shield must be ground connected at 360” using the omega connectors available on the support
panel of the regulation board, in front of the terminals strip on the bar above the board.
Note: cable shields are grounded at one end only.

GEI-100353
GROUND CONNECTION OF THE ANALOG ZERO VOLT FOR OPTIONAL TBO CARD
The common references of the TBO analog signals (terminal 2 and 4) must be connected to terminal 11 of the
drive regulation board.
For the RS300 device the common reference of the analog output signals (terminal 22) must be connected to
terminal 11 of the device regulation board.
The minimum distance between parallel signals and power cables (supply cables of the motor ) is 30cm (12
inches). Possible crossings have to be made at 90”. In case of double cabinets (entry to the inside of the cabinet
on both sides with 2 different panels installed each other reverse side) it is advisable to have all signals cables
conveyed into ducts mounted on the inverter side (front) and to pass motor cables on the other side (back) trough
a hole made in the panel at the output of the inverter’s terminals.
In case of single cabinets, it is advisable to let the power cable run vertically, while those of signal horizontally,
keeping the maximum possible distance.
SHIELDING OF THE SUPPLY FOR AN AC MOTOR
The AC motors have to be supplied through a four pole shielded cable (three phases + green/yellow ground
wire), or through four unshielded cables, which are inserted inside a metal channel, consequently needing a
higher insulation (see relative safety standards). So, it is important that, further to the three phases, it has been a
direct connection (four cables) between the panel grounding and the motor and that the fourth cable had been
inserted in a shield.
GROUND CONNECTION TO BOTH SIDES OF THE CABLE SHIELD (AC MOTOR)
The shield of the supply cable of AC motors must be grounded on both sides in order to obtain a 360” contact,
that means the whole shield. This can be realized using suitable metallic EMC cables press grounded at 360” at
the input of the cabinet and of the motor’s terminal strip. If this connection is not possible, the shielded cables
should be brought inside the cabinet and connected with an omega connector (see figure) to the mounting panel.
The same must be done on the motor side: in case the connection at 360” on the motor’s terminal strip is not
possible, the shield must be grounded before entering into terminal strip, on the metal support of the motor,
using an omega connector (see figure). In case a metal duct has to be used, it should be both-sided grounded at
360” where possible.
PIGTAIL AVOIDING
While grounding the shielding of the cables, one has to adopt a 360” connection (E.g.: omega bus as in the table)
and the pigtail connection must be absolutely avoided. As pigtail here is meant the connection to earth of the
cable shield by means of a wire (or to use the same screen, roll it up and ground-connected).
SUPPLY CABLES OF THE DC MOTOR
The supply cables of DC motor do not need to be shielded.
DIRECT CONNECTION BETWEEN GROUND BUS AND MOTOR CHASSIS
Independently from any local ground-connection of the motor’s chassis, for safety reasons, it must always be
connected to the ground wire (yellow/green) coming from the panel ground bus.

From the grounding of the screen s&cabinet of the inverter terminal strip, the supply’s cables have to measure
at max. 5 meters (16.4 feet).
ENCODER CABLES
The encoder cable must be shielded and grounded only from the side of the inverter at 360”. The female connector
on the regulation board has been foreseen for that connection, therefore it is enough to have the cable shield
connected at 360” in the conductive case of the male connector.
In order to check that the shield is not connected on the motor side remove the encoder connector from the
inverter and verify with a tester the presence of a high impedance between the shield and the metal case of the
encoder or of the motor.
MOUNTING SEQUENCE FOR FN, COMPACT AND RANGER FILTERS WITH CONVERTER AND
LINE REGEN CONVERTER
In case of converters and line regen converetrs, these filters must be series-connected between the choke and the
AC line switch. The autotrasformer, in case of RS300 device, is always connected between the choke and regen
