Warnings

The Varispeed F7 DC bus capacitor remains charged even after the power has been
switched off. To avoid an electric shock hazard, disconnect the frequency inverter from the
mains before carrying out maintenance. Then wait for at least 5 minutes after all LEDs
have gone out.
Do not perform a withstand voltage test on any part of the Varispeed. The frequency
inverter contains semiconductors, which are not designed for such high voltages.

Do not remove the digital operator while the mains supply is switched on. The printed cir­cuit board must also not be touched while the inverter is connected to the power.

CAUTION

CAUTION

Cables must not be connected or disconnected, nor signal tests carried out,

while the power is switched on.

Never connect general LC/RC interference suppression filters, capacitors or overvoltage
protection devices to the inverter input or output.

To avoid unnecessary overcurrent faults, etc. being displayed, the signaling contacts of any
contactor or switch fitted between inverter and motor must be integrated into the inverter
control logic (e.g. baseblock).

This is absolutely imperative!

This manual must be read thoroughly before connecting and operating the inverter. All
safety precautions and instructions for use must be followed.

The inverter may must be operated with the appropriate line filters, following the installation
instructions in this manual and with all covers closed and terminals covered.
Only then will adequate protection be provided. Please do not connect or operate any
equipment with visible damage or missing parts. The operating company is responsible
for any injuries or equipment damage resulting from failure to heed the warnings in this
manual.

EN-2

 Safety Precautions and Instructions

 General

Please read these safety precautions and instructions for use thoroughly before installing and oper­ating this inverter. Also read all of the warning signs on the inverter and ensure they are never dam­aged or removed.

Live and hot inverter components may be accessible during operation. Removal of housing compo­nents, the digital operator or terminal covers runs the risk of serious injuries or damage in the event
of incorrect installation or operation. The fact that frequency inverters control rotating mechanical
machine components can give rise to other dangers.

The instructions in this manual must be followed. Installation, operation and maintenance may only
be carried out by qualified personnel. For the purposes of the safety precautions, qualified personnel
are defined as individuals who are familiar with the installation, starting, operation and maintenance
of frequency inverters and have the proper qualifications for this work. Safe operation of these units
is only possible if they are used properly for their intended purpose.

The DC bus capacitors can remain live for about 5 minutes after the inverter is disconnected from
the power. It is therefore necessary to wait for this time before opening its covers. All of the main cir­cuit terminals may still carry dangerous voltages.

Children and other unauthorized persons must not be allowed access to these inverters.
Keep these Safety Precautions and Instructions for Use readily accessible and supply them to all

persons with any form of access to the inverters.

 Intended Use

Frequency inverters are intended for installation in electrical systems or machinery.
Their installation in machinery and systems must conform to the following product standards of the

Low Voltage Directive:
EN 50178, 1997-10, Equipping of Power Systems with Electronic Devices
EN 60204-1, 1997-12 Machine Safety and Equipping with Electrical Devices

Part 1: General Requirements (IEC 60204-1:1997)/
Please note: Includes Corrigendum of September 1998

EN 61010-1, A2, 1995 Safety Requirements for Information Technology Equipment

(IEC 950, 1991 + A1, 1992 + A2, 1993 + A3, 1995 + A4, 1996, modified)

CE marking is carried out to EN 50178, using the line filters specified in this manual and following
the appropriate installation instructions.

 Transportation and storage

The instructions for transportation, storage and proper handling must be followed in accordance with
the technical data.

 Installation

Install and cool the inverters as specified in the documentation. The cooling air must flow in the
specified direction. The inverter may therefore only be operated in the specified position (e.g.
upright). Maintain the specified clearances. Protect the inverters against impermissible loads. Com­ponents must not be bent nor insulation clearances changed. To avoid damage being caused by
static electricity, do not touch any electronic components or contacts.

EN-3

 Electrical Connection

Carry out any work on live equipment in compliance with the national safety and accident prevention
regulations. Carry out electrical installation in compliance with the relevant regulations. In particular,
follow the installation instructions ensuring electromagnetic compatibility (EMC), e.g. shielding,
grounding, filter arrangement and laying of cables. This also applies to equipment with the CE mark.
It is the responsibility of the manufacturer of the system or machine to ensure conformity with EMC
limits.

Your supplier or Omron Yaskawa Motion Control representative must be contacted when using leak­age current circuit breaker in conjunction with frequency inverters.

In certain systems it may be necessary to use additional monitoring and safety devices in compli­ance with the relevant safety and accident prevention regulations. The frequency inverter hardware
must not be modified.

 Notes

The Varispeed F7 frequency inverters are certified to CE, UL, and cUL

 EMC Compatibility

 Introduction

This manual was compiled to help system manufacturers using OMRON YASKAWA Motion Control
(OYMC) frequency inverters design and install electrical switch gear. It also describes the measures
necessary to comply with the EMC Directive. The manual's installation and wiring instructions must
therefore be followed.

Our products are tested by authorized bodies using the standards listed below.
Product standard: EN 61800-3:1996

EN 61800-3; A11:2000

 Measures to Ensure Conformity of OYMC Frequency inverters to the EMC Directive

OYMC frequency inverters do not necessarily have to be installed in a switch cabinet.
It is not possible to give detailed instructions for all of the possible types of installation. This manual

therefore has to be limited to general guidelines.
All electrical equipment produces radio and line-borne interference at various frequencies. The

cables pass this on to the environment like an aerial.
Connecting an item of electrical equipment (e.g. drive) to a supply without a line filter can therefore

allow HF or LF interference to get into the mains.
The basic countermeasures are isolation of the wiring of control and power components, proper

grounding and shielding of cables.
A large contact area is necessary for low-impedance grounding of HF interference. The use of

grounding straps instead of cables is therefore definitely advisable.
Moreover, cable shields must be connected with purpose-made ground clips.

EN-4

 Laying Cables

Measures Against Line-Borne Interference:
Line filter and frequency inverter must be mounted on the same metal plate. Mount the two compo-

nents as close to each other as possible, with cables kept as short as possible.
Use a power cable with well-grounded shield. For motor cables up to 50 meters in length use

shielded cables. Arrange all grounds so as to maximize the area of the end of the lead in contact
with the ground terminal (e.g. metal plate).

Shielded Cable:

• Use a cable with braided shield.

• Ground the maximum possible area of the shield. It is advisable to ground the shield by connect-

ing the cable to the ground plate with metal clips (see following figure).

Ground Clip

Fig 1 Earthing the cable shield with metal clips

The grounding surfaces must be highly conductive bare metal. Remove any coats of varnish and
paint.

– Ground the cable shields at both ends.
– Ground the motor of the machine.

Installation

 Mechanical Installation

 Unpacking the Inverter

Check the following items after unpacking the inverter.

Item Method

Has the correct Inverter model been
delivered?

Is the Inverter damaged in any way?

Are any screws or other components
loose?

If any irregularities in the above items are found, contact the agency from which the Inverter was pur­chased or your Omron Yaskawa Motion Control representative immediately.

 Checking the Installation Site

Protection covers are attached to the top and bottom of the NEMA 1 / IP20 Inverters. Be sure to
remove the top cover before operating a 200 or 400 V Class Inverter with a capacity of 18.5 kW or
less inside a panel.

Observe the following precautions when mounting the Inverter:

• Install the Inverter in a clean location which is free from oil mist and dust. It can be installed in a

totally enclosed panel that is completely shielded from floating dust.

• When installing or operating the Inverter, always take special care so that metal powder, oil,

water, or other foreign matter does enter the Inverter.

• Do not install the Inverter on combustible material, such as wood.

• Install the Inverter in a location free from radioactive materials and combustible materials.

• Install the Inverter in a location free from harmful gasses and liquids.

• Install the Inverter in a location without excessive oscillation.

• Install the Inverter in a location free from chlorides.

• Install the Inverter in a location without direct sunlight.

Check the model number on the nameplate on the side of the
Inverter.
Inspect the entire exterior of the Inverter to see if there are any
scratches or other damage resulting from shipping.

Use a screwdriver or other tools to check for tightness.

EN-6

 Installation Orientation

Install the Inverter vertically so as not to reduce the cooling effect. When installing the Inverter,
always provide the following installation space to allow normal heat dissipation.

 Installation of Inverters and EMC filters

For an EMC rules compliant installation
consider the following points:

• Use a line filter.

• Use shielded motor cables.

• Mount the inverter and filter on a

grounded cunductive plate.

• Remove any paint or dirt before mount-

ing the parts in order to reach the low­est possible grounding impedance.

Consider the following precautions for the main circuit power supply input.

• If a moulded case circuit breaker is used for the power supply connection (R/L1, S/L2, and T/L3),

ensure that the circuit breaker is suitable for the Inverter.

• If an earth leakage breaker is used, it should be able to detect all kinds of current in order to

ensure a safe earth leakage current detection

EN-12

• A magnetic contactor or other switching device can be used at the inverter input. The inverter

should not be powered up more than once per hour.

• The input phases (R/S/T) can be connected in any sequence.

• If the Inverter is connected to a large-capacity power transformer (600 kW or more) or a phase

advancing capacitor is switched nearby, an excessive peak current could flow through the input
power circuit, causing an inverter damage. As a countermeasure install an optional AC Reactor
at the inverter input or a DC reactor at the DC reactor connection terminals.

• Use a surge absorber or diode for inductive loads near the Inverter. Inductive loads include mag-

netic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.

Wiring the Output Side of the Main Circuit

The following precautions should be considered for the output circuit wiring.

• Never connect any power source to the inverter output terminals. Otherwise the inverter can be

damaged.

• Never short or ground the output terminals. Otherwise the inverter can be damaged.

• Do not use phase correction capacitors. Otherwise the inverter and capacitors can be damaged.

• Check the control sequence to make sure, that the magnetic contactor (MC) between the Inverter

and motor is not turned ON or OFF during inverter operation. If the MC is turned ON during the
Inverter is operation, a large inrush current will be created and the inverter’s overcurrent protec­tion may operate.

Ground Connection

The following precautions should be considered for the ground connection.

• Do not share the ground wire with other devices, such as welding machines or power tools.

• Always use a ground wire, that complies with technical standards on electrical equipment and

minimize the length of the ground wire.
Leakage current is caused by the Inverter. Therefore, if the distance between the ground elec­trode and the ground terminal is too long, potential on the ground terminal of the Inverter will
become unstable.

• When more than one Inverter is used, do not to loop the ground wire.

OK

Fig 7 Ground Wiring

NO

Control Circuit Wiring Precautions

Consider the following precautions for wiring the control circuits.

• Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1,

V/T2, W/T3, B1, B2, , 1, 2, and 3, PO, NO) and other high-power lines.

• Separate wiring for control circuit terminals MA, MB, MC, M1 to M6 (relay outputs) from wiring to

other control circuit terminals.

• If an optional external power supply is used, it should be a UL Listed Class 2 power supply.

• Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating faults.

• Ground the cable shields with the maximum contact area of the shield and ground.

• Cable shields have to be grounded on both cable ends.

 Before Power Up

The following points should be checked carefully before the power is switched on.

• Check if the power supply meets the inverter specification.

• Check if the power supply cables are tightly connected to the right terminals (L1, L2, L3).

• Check if the motor cables are tightly connected to the right terminals on the inverter side (U, V,

W) as well as on the motor side.

• Check if the braking unit / braking resistor is connected correctly.

• Check if the Inverter control circuit terminal and the control device are wired correctly.

• Set all Inverter control circuit terminals to OFF.

• When a PG card is used, check if it is wired correctly.

 Autotuning

Autotuning sets motor parameters automatically when using Open Loop or Closed Loop Vector con­trol, when the cable length is long or the installation has changed.

 Setting the Autotuning Mode

One of the following three autotuning modes can be set.

• Rotating autotuning

• Non-rotating autotuning

• Non-rotating autotuning for line-to-line resistance only

EN-16

Rotating Autotuning (T1-01 = 0)

Rotating autotuning is used for Open Loop and Closed Loop Vector control only. Set T1-01 to 0,
input the data from the motor nameplate, and then press the RUN key on the Digital Operator. The
Inverter will operate the motor for approximately 1 minute and set the required motor parameters
automatically.

Non-rotating Autotuning (T1-01 = 1)

Non-rotating autotuning is used for Open Loop and Closed Loop Vector control only. Set T1-01 to 1,
input the data from the motor nameplate, and then press the RUN key on the Digital Operator. The
inverter will supply power to the non-rotating motor for approximately 1 minute and some of the

motor parameters will be set automatically. The remaining motor parameters will be set automati­cally during the first time operation.

Non-rotating Autotuning for Line-to-Line Resistance (T1-01 = 2)

Non-rotating autotuning for line-to-line resistance can be used in any control mode. This is the only
possible autotuning for V/f control and V/f control with PG.

It can be used to improve the performance when the motor cable is long, the cable length has
changed or when the motor and inverter have different capacities.

To perform autotuning in V/f control or V/f control with PG, set T1-02 (Motor rated power) and T1-04
(Motor rated current) and then press the RUN key on the Digital Operator. The Inverter will supply
power to the non-rotating motor for approximately 20 seconds and the Motor line-to-line resistance
and cable resistance will be automatically measured.

1. Power will be supplied to the motor during autotuning but the motor will not turn. Do not touch the motor
until autotuning has been completed.

IMPORTANT

2. Ensure that all motor contactors are closed before the autotuning is started.

3. To cancel autotuning press the STOP key on the Digital Operator.

Troubleshooting

 General Faults and Alarms

Faults and Alarms indicate unsusal inverter / application conditions.
An alarm does not necessarily switch off the inverter but a message is displayed on the keypad (i.e.

a flashing alarm code) and an alarm output can be generated at the multi-function outputs (H2-01
and H2-02) if programmed. An alarm automatically disappears if the alarm condition is not present
anymore.

A fault switches the inverter output off immediately, a message is displayed on the keypad and the
fault output is switched. The fault must be reset manually after the cause and the RUN signal have
been removed.

The following table shows a list of faults and alarms with their corrective actions.

Warnhinweise

Solange die Versorgungsspannung eingeschaltet ist, dürfen weder Kabel an- oder

abgeklemmt werden, noch dürfen Signalprüfungen durchgeführt werden.

Der Zwischenkreis des Varispeed F7 bleibt auch dann geladen, wenn die
Spannungsversorgung unterbrochen wurde. Trennen Sie den Frequenzumrichter vor
Ausführung von Wartungsarbeiten von der Spannungsversorgung, um einen elektrischen
Schlag zu vermeiden. Warten Sie anschließend mindestens 5 Minuten, bis alle LEDs
erloschen sind.
Führen Sie an keinem Teil des Varispeed Spannungsfestigkeitstests durch. Der
Frequenzumrichter enthält Halbleiter, die für derart hohe Spannungen nicht ausgelegt sind.

Die digitale Bedienkonsole darf nicht bei eingeschalteter Spannungsversorgung abgebaut
werden. Berühren Sie keine Platinen, wenn der Frequenzumrichter an die
Spannungsversorgung angeschlossen ist.

ACHTUNG

ACHTUNG

Schließen Sie niemals LC/RC-Entstörfilter, Kondensatoren oder
Überspannungsschutzgeräte an den Ein- oder Ausgang des Frequenzumrichters an,
die nicht speziell für den Frequenzumrichter vorgesehen sind.

Um unnötige Überstromfehler usw. zu vermeiden, müssen die Signalkontakte aller Schütze
oder Schalter, die zwischen Frequenzumrichter und Motor geschaltet sind, in die
Steuerungslogik (z. B. Endstufensperre) eingebunden sein.

Das ist zwingend erforderlich!

Dieses Handbuch muss vor Anschluss und Inbetriebnahme des Frequenzumrichters
sorgfältig durchgelesen werden. Alle Sicherheitshinweise und Anleitungen müssen
beachtet werden.

Der Frequenzumrichter muss gemäß Installationsanleitungen in diesem Handbuch mit
geeigneten Netzfiltern betrieben werden. Zudem müssen alle Abdeckungen geschlossen
und alle Klemmen abgedeckt sein.
Nur dann ist ein angemessener Schutz gesichert. Geräte mit sichtbaren Beschädigungen
oder fehlenden Teilen dürfen nicht angeschlossen oder in Betrieb genommen werden.
Der Betreiber der Geräte ist für alle Verletzungen oder Geräteschäden verantwortlich,
die aus Nichtbeachtung der Warnhinweise in diesem Handbuch entstehen.

DE-2

 Sicherheitshinweise und Anleitungen

 Allgemein

Lesen Sie diese Sicherheitshinweise und Anleitungen vor Installation und Inbetriebnahme dieses
Frequenzumrichters. Lesen Sie auch alle Warnhinweise, die auf dem Frequenzumrichter
angebracht sind, und achten Sie darauf, dass diese nicht beschädigt oder entfernt werden.

Während des Betriebs können unter Spannung stehende oder heiße Bauteile zugänglich sein.
Durch Entfernen von Verkleidungsteilen, der digitalen Bedienkonsole oder Klemmenabdeckungen
besteht im Falle einer fehlerhaften Installation oder Bedienung das Risiko von ernsthaften
Verletzungen. Durch die Tatsache, dass Frequenzumrichter drehende mechanische Teile von
Maschinen steuern, können weitere Gefahren entstehen.

Den Anleitungen in diesem Handbuch muss Folge geleistet werden. Installation, Bedienung oder
Wartung darf nur durch qualifiziertes Personal erfolgen. Aus Sicherheitsgründen sind als
qualifizierte Mitarbeiter nur solche anzusehen, die mit der Installation, dem Starten, der Bedienung
und der Wartung von Frequenzumrichtern vertraut sind und für diese Arbeiten entsprechende
Qualifikationen besitzen. Ein sicherer Betrieb dieser Geräte ist nur möglich, wenn diese auch für
den vorgesehenen Zweck eingesetzt werden.

Der Zwischenkreis kann nach Abschalten der Versorgungsspannung des Frequenzumrichters noch
ca. 5 Minuten lang unter Spannung stehen. Aus diesem Grund muss diese Zeitspanne vor dem
Öffnen von Geräteabdeckungen abgewartet werden. Alle Klemmen des Hauptstromkreises können
noch gefährliche Spannungen führen.

Kinder und andere nicht autorisierte Personen dürfen keinen Zugang zu Frequenzumrichtern haben.
Bewahren Sie diese Sicherheitshinweise und Anleitungen griffbereit auf, und lassen Sie sie allen

Personen zukommen, die Zugang zu den Frequenzumrichtern haben.

 Vorgesehener Verwendungszweck

Frequenzumrichter sind für den Einbau in elektrische Systeme oder Maschinen gedacht.
Ihr Einbau in Maschinen oder Systeme muss folgenden Produktstandards der Niederspannungs-

richtlinie entsprechen:
EN 50178, 1997-10, Ausrüstung von Starkstromanlagen mit elektronischen Betriebsmitteln
EN 60204-1, 1997-12 Sicherheit von Maschinen - Elektrische Ausrüstung von Maschinen

Teil 1: Allgemeine Anforderungen (IEC 60204-1: 1997)/
Bitte beachten Sie Folgendes: Enthält Ergänzungen von September 1998

EN 61010-1, A2, 1995 Sicherheitsbestimmungen für elektrische Mess-, Steuer-, Regel- und

Laborgeräte
(IEC 950, 1991 + A1, 1992 + A2, 1993 + A3, 1995 + A4, 1996, modifiziert)

Die CE-Kennzeichnung erfolgt gemäß EN 50178 bei Verwendung der in diesem Handbuch
spezifizierten Netzfilter und dem Befolgen der entsprechenden Installationsanleitungen.

 Transport und Lagerung

Die Anleitungen für Transport, Lagerung und richtige Handhabung müssen unter Beachtung der
technischen Daten befolgt werden.

 Installation

Installieren und kühlen Sie Frequenzumrichter wie in der Dokumentation spezifiziert. Die Kühlluft
muss in der angegebenen Richtung strömen. Der Frequenzumrichter darf dementsprechend nur in
der spezifizierten Position (z. B. aufrecht) betrieben werden. Halten Sie die angegebenen Freiräume
ein. Schützen Sie die Frequenzumrichter vor unzulässigen Lasten. Bauteile dürfen nicht verbogen
werden. Isolationsabstände dürfen nicht geändert werden. Berühren Sie keine elektronischen
Bauteile oder Kontakte, um Beschädigungen durch statische Elektrizität zu vermeiden.

DE-3

 Elektrischer Anschluss

Führen Sie jegliche Arbeiten an unter Spannung stehenden Geräten gemäß der gültigen
Sicherheits- und Unfallverhütungsvorschriften durch. Führen Sie die elektrische Installation in
Übereinstimmung mit den geltenden Vorschriften durch. Insbesondere müssen Sie die
Anweisungen zur Sicherstellung der elektromagnetischen Verträglichkeit (EMV), z. B. Abschirmung,
Erdung, Filteranordnung und Verlegung von Kabeln, beachten. Das gilt auch für Geräte, die das CE­Zeichen tragen. Es liegt in der Verantwortung des Herstellers von System oder Maschine, die
Konformität mit den EMV-Richtlinien zu gewährleisten.

Wenden Sie sich an Ihren Lieferanten oder die Omron Yaskawa Motion Control-Vertretung, wenn
Fehlerstrom-Schutzschalter in Verbindung mit Frequenzumrichtern Verwendung finden.

Für bestimmte Systeme kann es erforderlich sein, gemäß den gültigen Sicherheits- und
Unfallverhütungsvorschriften zusätzliche Überwachungs- und Sicherheitseinrichtungen zu verwenden.
An der Hardware des Frequenzumrichters dürfen keine Änderungen vorgenommen werden.

 Hinweise

Die Frequenzumrichter Varispeed F7 sind gemäß CE, UL und cUL zertifiziert.

 Elektromagnetische Verträglichkeit

 Einführung

Dieses Handbuch wurde erstellt, um Systemhersteller, die OMRON YASKAWA Motion Control
(OYMC)-Frequenzumrichter verwenden, bei der Konstruktion und Installation von elektrischen
Schaltgeräten zu unterstützen. Zudem werden die zur Einhaltung der EMV-Richtlinie erforderlichen
Maßnahmen beschrieben. Die Anleitungen zur Installation und Verdrahtung in diesem Handbuch
müssen deshalb befolgt werden.

Unsere Produkte sind durch autorisierte Stellen unter Anwendung der nachstehend aufgelisteten
Normen getestet.

Produktnorm: EN 61800-3:1996

EN 61800-3; A11:2000

 Maßnahmen zur Sicherstellung der Konformität von OYMC-Frequenzumrichtern mit

der EMV-Richtlinie

OYMC-Frequenzumrichter müssen nicht unbedingt in einem Schaltschrank eingebaut werden.
Detaillierte Anleitungen für alle möglichen Installationsarten können nicht gegeben werden. Dieses

Handbuch muss daher auf allgemeine Leitlinien begrenzt bleiben.
Alle elektrischen Geräte produzieren Funkstörungen und leitungsgeführte Störungen mit

unterschiedlichen Frequenzen. Die Kabel leiten diese Störungen wie eine Antenne an die
Umgebung weiter.

Der Anschluss eines elektrischen Geräts (z. B. Frequenzumrichter) ohne Netzfilter an ein Stromnetz
kann deshalb bewirken, dass HF- oder NF-Störungen in das Stromnetz gelangen.

DE-4

Die grundlegenden Gegenmaßnahmen sind die räumliche Trennung der Kabel von Steuer- und
Leistungskomponenten, ordnungsgemäße Erdung sowie die Abschirmung von Kabeln.

Für eine Niedrigimpedanz-Erdung von HF-Störungen ist eine große Kontaktfläche erforderlich.
Die Verwendung von Erdungsbändern anstelle von Kabeln wird ausdrücklich empfohlen.

Des weiteren müssen Kabelabschirmungen mit entsprechenden Erdungsschellen verbunden werden.

 Verlegen von Kabeln

Maßnahmen gegen leitungsgebundene Störungen:
Netzfilter und Frequenzumrichter müssen auf dieselbe Metallplatte montiert werden. Montieren Sie die

beiden Bauteile so nah wie möglich nebeneinander, und halten Sie die Kabel so kurz wie möglich.
Verwenden Sie ein Netzkabel mit gut geerdeter Abschirmung. Verwenden Sie ein abgeschirmtes

Motorkabel. Ordnen Sie alle Erdungen so an, dass die Fläche des Kabelendes, die mit der
Erdungsklemme in Kontakt ist (z. B. Metallplatte), möglichst groß ist.

Abgeschirmtes Kabel:

• Verwenden Sie ein Kabel mit geflochtener Abschirmung.

• Erden Sie die größtmögliche Fläche der Abschirmung. Es ist ratsam, die Abschirmung durch

Verbinden des Kabels mit der Erdungsplatte durch Metallschellen (siehe nachfolgende
Abbildung) zu erden.

Erdungsschelle

Abb 1 Erdung der Kabelabschirmung mit Metallschellen

Die Erdungsflächen müssen aus hoch leitfähigem, blankem Metall bestehen. Entfernen Sie
Lack- und Farbbeschichtungen.

– Erden Sie die Kabelabschirmungen an beiden Enden.
– Erden Sie den Motor an der Maschine.
