1.1 Warnings, Cautions and Notes
NOTE
A Note contains information which helps to ensure correct operation of
the product.
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.
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 function of the drive does 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 drivehas 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 afault. Inany application
where a malfunction of the drive or its control system could leadto
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.
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 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).
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.

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 witha protection thermistor. Ifnecessary, an electricforcedvent
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.

2.4.1 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. The exact value for a specific motor can be calculated using the
equations detailed in Menu 4 in the Advanced User Guide.
Typical values are shown in the table below for RFC and open loop (OL) modes:
Table 2-2 Typical overload limits
Operating mode
RFC from cold
RFC from 100 %
Open loop from cold
Open loop from 100 %
Normal Duty overload with motor rated current =
drive rated current
110% for 180s
110% for 10 s*
110% for 180s
110 % for 10 s*
Heavy Duty overload with motor rated current =
drive rated current
140 % for 60 s
140 % for 10 s
140 % for 60 s
140 % for 10 s
* 1240720T rating provides 110 % for 3 s from rated normal duty current. 110 % is available for 10 s when limited to 850 A continuous.
12406600T and 12405660T support 110 % for 10 s.
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.
NOTE
The maximum overload level which can be attained is independent of the speed.

3.2 Lifting the Power Module
When removing the Power Module from the packaging, connect bow
shackles rated to 500 kg (1102 lbs) to the two lifting points, which
measure 17.5mm diameter, shownin Figure 3-1, and slowly raise into
a verticalposition.
Figure 3-1 Lifting the Power Module
3.3 Planning the installation
The following considerations must be made when planning the
installation:
3.3.1 Access
Access must be restricted to authorized personnel only.
Safety regulations which apply at the place of use must be complied
with.
3.3.2 Environmental protection
The drive must be protected from:
• Moisture, including dripping water or spraying waterand
condensation.
• Contamination with electrically conductive material
• Contamination with any form of dust which may restrict the fan, or
impair airflow over various components
• Temperature beyond the specified operating and storageranges
• Corrosive gasses
3.3.3 Cooling
The inlet and outlet vents on the drive must not be restricted or covered.
The ambient temperature must not exceed the specified operating
temperature of the drive.
3.3.4 Electrical safety
The installation must be safe under normal and fault conditions.
Electrical installation instructions are given in Chapter 4 Electrical
Installation on page 46.
3.3.5 Fire protection
The drive enclosure is not classified as a fire enclosure. A separate fire
enclosure must be provided.
For installation in the USA, a NEMA 12 enclosure is suitable.
For installation outside the USA, the following (based on IEC 62109-1,
standard for PV inverters) is recommended.
Enclosure can be metal and/or polymeric, polymer must meet
requirements which can be summarized for larger enclosures as using
materials meeting at least UL 94 class 5VB at the point of minimum
thickness.
Air filter assemblies to be at least class V-2.
The location and size of the bottom shall cover the area shown in
Figure 3-2. Any part of the side which is within the area traced out by the
5° angle is also considered to be part of the bottom of the fireenclosure.
Figure 3-2 Fire enclosure bottom layout
The bottom, including the part of the side considered to be part of the
bottom, must be designed to prevent escape of burning material - either
by having no openings or by having a baffle construction. This means
that openings for cables etc. must be sealed with materials meeting the
5VB requirement, or else have a baffle above.
See Figure 3-3 for acceptable baffle construction. This does not apply
for mounting in an enclosed electrical operating area (restricted access)
with concrete floor.
Figure 3-3 Fire enclosure baffle construction
3.3.6 Electromagnetic compatibility
Variable speed drives are powerful electronic circuits which can cause
electromagnetic interference if not installed correctly with careful
attention to the layout of the wiring.
Some simple routine precautions can prevent disturbance to typical
industrial control equipment.
If it is necessary to meet strict emission limits, or if it is known that
electromagnetically sensitive equipment is located nearby, then full
precautions must be observed. In-built into the drive, is an internal
EMC filter, which reduces emissions under certain conditions. If these
conditions are exceeded, then the use of an external EMC filter may be
required at the drive inputs, which must be located as close to the drive
as possible.
Lifting and handling
Always lift the drive by the lifting points. Care must be taken
when lifting as the Power Module could overbalance if not
WARNING lifted correctly. Wear safety shoes.
