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
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, 1997-12Machine 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, 1995Safety 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.

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.
