Safety Information and Precautions
Warnings, Cautions and Notes
WARNING
A Warning contains information, which is essential for avoiding a safety hazard.
CAUTION
A Caution contains information, which is necessary for avoiding a risk of damage to the product or
other machine.
Note
A Note contains information which helps to ensure correct operation.
Electrical Safety
Extreme care must be taken at all times when working with the AC Drive or within the area of the AC Drive.
The voltages used in the AC Drive can cause severe electrical shock or burns and is potentially lethal. Only
authorized and qualified personnel should be allowed to work on AC Drives
Machine/System Design and Safety of Personnel
Machine/system design, installation, commissioning startups and maintenance must be carried out by
personnel who have the necessary training and experience. They must read this safety information and the
contents of this manual. If incorrectly installed, the AC Drive may present a safetyhazard.
The AC Drive uses high voltages and currents (including DC), carries a high level of stored electrical energy
in the DC bus capacitors even after power OFF.These high voltages are potentially lethal.
The AC Drive is NOT intended to be used for safety related applications/functions. The electronic “STOP &
START” control circuits within the AC Drive must not be relied upon for the safety of personnel. Such control
circuits do not isolate mains power voltages from the output of the AC Drive. The mains power supply must
be disconnected by a electrical safety isolation device before accessing the internal parts of the AC Drive.
Safety risk assessments of the machine or process system which uses an AC Drive must be undertaken
by the user and or by their systems integrator/designer. In particular the safety assessment/design must
take into consideration the consequences of the AC Drive failing or tripping out during normal operation and
whether this leads to a safe stop position without damaging machine, adjacent equipment and machine
operators/users. This responsibility lies with the user or their machine/process systemintegrator.
The system integrator/designer must ensure the complete system is safe and designed according to the
relevant safety standards. K&R Technology and Authorized Distributors can provide recommendations
related to the AC drive to ensure long term safe operation.

Safety Information and Precautions
Working Environment and Handling
Matters related to transport, storage, installation, IP rating, working environment and AC Drive tolerance
limits (temperature, ambient, voltage, pollution, vibration etc) can be found within this manual. The guidelines
and recommendations should be followed in order to gain long term trouble free operation as the lifetime
of the AC Drive is dependent on the working environment and correct handling of the product in the initial
installation stage.
Electrical Installation - Safety
Electrical shock risk is always present within an AC Drive including the output cable leading to the motor
terminals. Where dynamic brake resistors are fitted external to the AC Drive, care must be taken with regards
to live contact with the brake resistors, terminals which are at high DC voltage and potentially lethal. Cables
from the AC Drive to the dynamic brake resistors should be double insulated as DC voltages are typically 600
to 700 VDC.
Mains power supply isolation switch should be fitted to the AC Drive. The mains power supply must be
disconnected via the isolation switch before any cover of the AC Drive can be removed or before any
servicing work is undertaken
Stored charge in the DC bus capacitors of the PWM AC Drive is potentially lethal after the AC supply has
been disconnected. The AC supply must be isolated at least 10 minutes before any work can be undertaken
as the stored charge will have been discharged through the internal bleed resistor fitted across the DC bus
capacitors.
Whenever possible, it is good practice to check the DC bus voltage with a VDC meter before accessing
the AC Drive bridge. Where the AC Drive input is connected to the mains supply with a plug and socket,
then upon disconnecting the plug and socket, be aware that the plug pins may be exposed and internally
connected to the DC bus capacitors (via the internal bridge rectifier in reversed bias). Wait 10 minutes to
allow stored charge in the DC bus capacitors to be dissipated by the bleed resistors before commencing
work on the AC Drive.
When using an earth leakage circuit breaker, use a residual current operated protective device (RCD) of
type B (breaker which can detect both AC and DC). Leakage current can cause unprotected components to
operate incorrectly. If this is a problem, lower the carrier frequency, replace the components in question with
parts protected against harmonic current, or increase the sensitivity amperage of the leakage breaker to at
least 200 mA per drive.
Factors in determining leakage current:
•Size of the ACdrive
•AC drive carrier frequency
•Motor cable type and length
•EMI/RFI filter
For more information, contact K&R.
Approvals
Certification marks on the product nameplate indicate compliance with the corresponding certificates and
standards.

Safety Information and Precautions
- 6 -
•The above EMC directives are complied with only when the EMC electric installation requirements
are strictly observed.
•Machines and devices used in combination with this drive must also be CE certified and marked.
The integrator who integrates the drive with the CE mark into other devices has the responsibility
of ensuring compliance with CE standards and verifying that conditions meet European standards.
•The installer of the drive is responsible for complying with all relevant regulations for wiring, circuit
fuse protection, earthing, accident prevention and electromagnetic (EMC regulations). In particular
fault discrimination for preventing fire risk and solid earthing practices must be adhered to for
electrical safety (also for good EMC practice).
•For more information on certification, consult our distributor or sales representative.
AC Motor (Induction/Asynchronous)
AC induction motors are designed to run at fixed speed at the 50 or 60 Hz supply frequency and therefore it’s
cooling capability is dependent on the axial driven fan mounted at the non drive end.
When the motor is operated at variable speed with the AC Drive, it is necessary to consider the reduced
cooling rate especially when running at low speed for considerable period of time. Please consult with the
motor manufacturer who can provide cooling solutions such as a electric force ventilated fan or an “AC Drive”
rated AC motor designed to handle reduced speed running with AC Drives.
It is also necessary to consult with the motor manufacturer when above base speed (> 50/60 Hz) running is
required and or when high speed operations are required. Motor suppliers also provide solutions for encoder
feedback devices for close loop operation with an AC Drive.
Adjusting AC Drive Parameters
The AC Drive when it leaves the factory with default settings should enable the user to get started quickly
to check on the basic mechanical running conditions. At a later time, fine tuning to optimize the operation/
performance can be undertaken.
Such parameter tuning should be done by qualified personnel who have prior training on AC Drives. Some
parameter settings if manipulated incorrectly can have adverse reactions and care should be taken especially
during the commissioning startup stages to prevent personnel from engaging the machine.
This manual provides a complete list of the parameters with functional description and care should always be
taken whenever parameters are adjusted during a live running startup. K&R Technology and Authorized
Distributors can provide product training and if in doubt seek advice.
