2.4.3. Directives on the use of the drives
It is extremely important that the module's technical data and information about connections (plate and documentation) are
always available and complied with.
fi
�
Only quali ed technical personnel familiar with transport, installation, assembly and commissioning may carry out these
activities.
Quali
fi
�
ed personnel shall be familiar with and observe the following standards:
• IEC 60364 and IEC 60664
• National accident prevention regulations
The drives contain electro-statically sensitive components, which may be damaged by handling if touching a conductive object
that is earthed.
Electrostatic charge should be discharged before handling the drive and positioning it on a conductive surface.
2.4.3.1. Use as directed
Drives are safety devices that are built into electrical plants or machines, and can only be operated as integral components of
such plants or machines.
The manufacturer must produce a risk analysis for the machine, and take appropriate measures to prevent unforeseen
movements that can cause injury or damage to persons or property.
If the drives are used in residential areas, in business areas, or in small industrial operations, then additional
�
lters must be
implemented by the user after full system measures.
2.4.3.2. Distribution board and connections
The drives must only operate in distribution boards or closed control cabinets. Ventilation or cooling may be required depending
on the external environmental conditions.
Use only copper conductors for wiring.
Conductor cross-sections must conform to the IEC 60204 standard.
2.4.3.3. Power supply
The DM2020 series drives (overvoltage category III according to EN 61800-5-1) may be powered by three-phase earthed
industrial electric networks (TN system, TT system with earthed neutral point, no more than 10 KA symmetrical rated current at
208 V -10%, 230 V, 240 V, 400 V or 480 V +10%).
Overvoltages between phases and the drive housing must not be higher than the peak of 1000 V.
According to the EN61800-3 standard, voltage transient peaks (< 50 ms) between phases must not exceed 1000 V.
Voltage transient peaks (< 50 µs) between a phase and housing must not exceed 2000 V.
2.4.3.4. Motors
The DM2020 drives have been designed for operating brushless synchronous motors and asynchronous motors with torque,
velocity and/or position control. The rated voltage of the motors must be at least as high as the DC-link voltage divided by two
produced by the drive.
2.4.3.5. Prohibited use
Usage which differs from that described in section “2.4.3.1. Use as directed” are not recommended, and could cause damage to
persons, equipment or other items.
Use of the drive is normally prohibited in the following environments:
• potentially explosive areas
• areas with corrosive and/or electrically conductive acids, alkaline solutions, oils, vapours,
• directly on unearthed electrical networks or on asymmetrically earthed power supplies with a voltage above 240 V
• on ships or offshore installations
Installing and starting up the drive is prohibited if the machine in which it is to be installed:
• does not conform to the requirements of the EC Machinery Directive
• does not conform to the EMC Directive or Low Voltage Directives
• does not conform to national regulations
The control of brake holding by the DM2020 drive alone may not be used in applications where personnel security is to be ensured
with the motor brake.
