10 DFS1/DFS2 Power Installation Guide
Issue Number: 2
1 Safety information
1.1 Warnings, Cautions and Notes
1.2 General information
This guide applies to products which control electric motors either directly (drives) or indirectly
(controllers, option modules and other auxiliary equipment and accessories). In all cases the hazards
associated with powerful electrical drives are present, and all safety information relating to drives and
associated equipment must be observed.
Specific warnings are given at the relevant places in this guide.
Drives and controllers are intended as components for professional incorporation into complete
systems. If installed incorrectly they may present a safety hazard. The drive uses high voltages and
currents, carries a high level of stored electrical energy, and is used to control equipment which can
cause injury. Close attention is required to the electrical installation and the system design to avoid
hazards either in normal operation or in the event of equipment malfunction. System design,
installation, commissioning/start-up and maintenance must be carried out by personnel who have the
necessary training and competence. They must read this safety information and this guide carefully.
1.3 Responsibility
It is the responsibility of the installer to ensure that the equipment is installed correctly with regard to
all instructions given in this guide. They must give due consideration to the safety of the complete
system, so as to avoid the risk of injury both in normal operation and in the event of a fault or of
reasonably foreseeable misuse.
The manufacturer accepts no liability for any consequences resulting from inappropriate, negligent or
incorrect installation of the equipment.
1.4 Compliance with regulations
The installer is responsible for complying with all relevant regulations, such as national wiring
regulations, accident prevention regulations and electromagnetic compatibility (EMC) regulations.
Particular attention must be given to the cross-sectional areas of conductors, the selection of fuses
or other protection, and protective ground (earth) connections.
This guide contains instructions for achieving compliance with specific EMC standards.
All machinery to be supplied within the European Union in which this product is used must comply
with the following directives:
2006/42/EC Safety of machinery.
2014/30/EU: Electromagnetic Compatibility.
A Warning contains information which is essential for avoiding a safety hazard.
A Caution contains information which is necessary for avoiding a risk of damage to the
product or other equipment.
A Note contains information, which helps to ensure correct operation of the product.

Safety information
Product information Mechanical installation Electrical installation Technical data
1.5 Electrical hazards
The voltages used in the drive can cause severe electrical shock and/or burns, and could be lethal.
Extreme care is necessary at all times when working with or adjacent to the drive. Hazardous voltage
may be present in any of the following locations:
• AC and DC supply cables and connections
• Output cables and connections
• Many internal parts of the drive, and external option units
Unless otherwise indicated, control terminals are single insulated and must not be touched.
The supply must be disconnected by an approved electrical isolation device before gaining access to
the electrical connections.
The STOP and Safe Torque Off functions of the drive do not isolate dangerous voltages from the
output of the drive or from any external option unit.
The drive must be installed in accordance with the instructions given in this guide. Failure to observe
the instructions could result in a fire hazard.
1.6 Stored electrical charge
The drive contains capacitors that remain charged to a potentially lethal voltage after the AC supply
has been disconnected. If the drive has been energized, the AC supply must be isolated at least ten
minutes before work may continue.
1.7 Mechanical hazards
Careful consideration must be given to the functions of the drive or controller which might result in a
hazard, either through their intended behaviour or through incorrect operation due to a fault. In any
application where a malfunction of the drive or its control system could lead to or allow damage, loss
or injury, a risk analysis must be carried out, and where necessary, further measures taken to reduce
the risk - for example, an over-speed protection device in case of failure of the speed control, or a
fail-safe mechanical brake in case of loss of motor braking.
With the sole exception of the Safe Torque Off function, none of the drive functions must be
used to ensure safety of personnel, i.e. they must not be used for safety-related functions.
The Safe Torque Off function may be used in a safety-related application. The system designer is
responsible for ensuring that the complete system is safe and designed correctly according to the
relevant safety standards.
The design of safety-related control systems must only be done by personnel with the required training
and experience. The Safe Torque Off function will only ensure the safety of a machine if it is correctly
incorporated into a complete safety system. The system must be subject to a risk assessment to
confirm that the residual risk of an unsafe event is at an acceptable level for the application.
1.8 Access to equipment
Access must be restricted to authorized personnel only. Safety regulations which apply at the place
of use must be complied with.
1.9 Environmental limits
Instructions in this guide regarding transport, storage, installation and use of the equipment must be
complied with, including the specified environmental limits. This includes temperature, humidity,
contamination, shock and vibration. Drives must not be subjected to excessive physical force.
1.10 Hazardous environments
The equipment must not be installed in a hazardous environment (i.e. a potentially explosive
environment).

12 DFS1/DFS2 Power Installation Guide
Issue Number: 2
1.11 Motor
The safety of the motor under variable speed conditions must be ensured.
To avoid the risk of physical injury, do not exceed the maximum specified speed of the motor.
Low speeds may cause the motor to overheat because the cooling fan becomes less effective,
causing a fire hazard. The motor should be installed with a protection thermistor. If necessary, an
electric forced vent fan should be used.
The values of the motor parameters set in the drive affect the protection of the motor. The default
values in the drive must not be relied upon. It is essential that the correct value is entered in the
Motor Rated Current parameter.
1.12 Mechanical brake control
Any brake control functions are provided to allow well co-ordinated operation of an external brake
with the drive. While both hardware and software are designed to high standards of quality and
robustness, they are not intended for use as safety functions, i.e. where a fault or failure would result
in a risk of injury. In any application where the incorrect operation of the brake release mechanism
could result in injury, independent protection devices of proven integrity must also be incorporated.
1.13 Adjusting parameters
Some parameters have a profound effect on the operation of the drive. They must not be altered
without careful consideration of the impact on the controlled system. Measures must be taken to
prevent unwanted changes due to error or tampering.
1.14 Electromagnetic compatibility (EMC)
Installation instructions for a range of EMC environments are provided in the relevant Power Installation
Guide. If the installation is poorly designed or other equipment does not comply with suitable standards
for EMC, the product might cause or suffer from disturbance due to electromagnetic interaction with
other equipment. It is the responsibility of the installer to ensure that the equipment or system into
which the product is incorporated complies with the relevant EMC legislation in the place of use.
1.15 Safe Torque Off
The Unidrive M700 / M701 has a single channel Safe Torque Off, whereas the Unidrive M702 has a
dual channel STO. The Safe Torque Off function provides a means for preventing the drive from
generating torque in the motor, with a very high level of integrity. It is suitable for incorporation into a
safety system for a machine. It is also suitable for use as a conventional drive enable input.
Machinery Applications
The Safe Torque Off function has been independently assessed by Notified Body, TüV Rheinland for
use as a safety component of a machine:
Prevention of unintended motor operation: The safety function “Safe Torque Off” can be used in
applications up to Cat 4, PL e according to EN ISO 13849-1, SIL 3 according to EN 61800-5-2/
EN 62061/ IEC 61508 and in lift applications according to EN 81-1 and EN 81-2.
TüV certificate No. 01.205/5270.02/17

Table 2-3 Protective ground cable ratings
Typical short-term overload limits
The maximum percentage overload limit changes depending on the selected motor. Variations in
motor rated current, motor power factor and motor leakage inductance all result in changes in the
maximum possible overload. Typical values are shown in the table below:
Table 2-4 Typical overload limits
Generally, the drive rated current is higher than the matching motor rated current allowing a higher
level of overload than the default setting.
The time allowed in the overload region is proportionally reduced at very low output frequency on
some drive ratings.
The maximum overload level which can be attained is independent of the speed.
Output current
The continuous output current ratings given on the rating label are for maximum 35 °C (95 °F),
1000 m altitude and 2 kHz switching frequency. Derating is required for higher switching frequencies,
ambient temperatures > 40 °C (104 °F). For further information, refer to Chapter 5.1 Drive technical
data on page 53.
Input current
The input current is affected by the supply voltage and impedance. The input current given on the
rating label is the typical input current and is stated for a balanced supply.

3 Mechanical installation
3.1 Safety information
Follow the instructions
The mechanical and electrical installation instructions must be adhered to. Any questions
or doubt should be referred to the supplier of the equipment. It is the responsibility of the
owner or user to ensure that the installation of the drive and any external option unit, and
the way in which they are operated and maintained, comply with the requirements of the
Health and Safety at Work Act in the United Kingdom or applicable legislation and
regulations and codes of practice in the country in which the equipment is used.
Stored charge
The drive contains capacitors that remain charged to a potentially lethal voltage after the
AC supply has been disconnected. If the drive has been energized, the AC supply must
be isolated at least ten minutes before work may continue.
Normally, the capacitors are discharged by an internal resistor. Under certain, unusual
fault conditions, it is possible that the capacitors may fail to discharge, or be prevented
from being discharged by a voltage applied to the output terminals. If the drive has failed
in a manner that causes the display to go blank immediately, it is possible the capacitors
will not be discharged. In this case, consult Nidec Industrial Automation or their authorized
distributor.
Competence of the installer
The drive must be installed by professional assemblers who are familiar with the
requirements for safety and EMC. The assembler is responsible for ensuring that the end
product or system complies with all the relevant laws in the country where it is to be used.
Enclosure
The drive is intended to be mounted in an enclosure which prevents access except by
trained and authorized personnel, and which prevents the ingress of contamination. It is
designed for use in an environment classified as pollution degree 2 in accordance with
IEC 60664-1. This means that only dry, non-conducting contamination is acceptable.
Hazardous areas
The drive must not be installed in a classified hazardous area unless it is installed in an
approved enclosure and the installation in certified.
Protection of equipment prior to installation
If the equipment is not to be installed immediately, it must be protected from moisture and
dust.
The equipment is delivered wrapped in plastic to protect it from mechanical damage. It is
recommended that wrapping is left in place until installation.
