2.7 Safe Use of the DM2020 System
The technical data (nameplate) and documentation for the ~DM2020 system and how to install its
components must be available to and observed by all personnel.
The drives contain electrostatically sensitive components, which can be damaged by electrostatic
discharge (ESD) through improper handling. It is recommended to follow proper ESD procedures to
discharge any electrostatic charge before handling the DM2020 system components (e.g., using
ESD straps, ESD mats or other protective surfaces, etc).
2.7.1 Risk Assessment
The drives are safe industrial devices that
are placed in electrical systems or machines and can
only be operated as integrated parts of those systems or machines. The builder/manufacturer of
the system or machine must generate a risk assessment, and take appropriate measures to avoid
unexpected movements that could cause death or injury to personnel and/or damage to equipment
or other property. The risk assessment must comply with all national, regional and local regulations
for the site where the system or machine will be operated. For more details, see Risk Assessment
on page 24.
2.7.2 Electrical Connections
The drives must operate only inside an enclosed control cabinet. Additional ventilation or cooling
may be necessary based on the external environmental conditions.
Use only copper conductors for wiring all connections. The conductor cross sections must comply
with IEC 60204.
2.7.3 Motor Selection
The DM2020 drives have been designed to control brushless asynchronous and synchronous
motors with torque control, speed and/or position. The rated voltage of the motors must be at
least the same level as:
produced by the drive. For more details on selecting the proper motor, see Motors on page 48.
2.7.4 Power Supply
The drives of the DM2020 series (overvoltage category III according to EN 61800-5-1) can be
powered by three-phase industrial AC supply, earthing systems (TN system, TT with grounded neutral
and symmetrical rated current not more than 10KA 120V to 480V ± 10%).
Overvoltage between phases and the drive housing must not be greater than 1000 V peak.
According to EN61800-3 transient voltage spikes (<50ms) between the phases must not exceed 1000
V. Transient voltage surge (<50μs) between a phase and the housing must not exceed 2000V.
