1.3 Safety and operating instructions
1.3.1 General terms
Warning: During assembly, testing, and normal operation, the
demonstration board poses several inherent hazards,
including bare wires, moving or rotating parts and hot
surfaces. There is a danger of serious personal injury if the
kit or components are improperly used or incorrectly
installed. The kit is not electrically isolated from the AC/DC
input. The demonstration board is directly linked to the mains
voltage. No insulation is ensured between accessible parts
and high voltage. All measuring equipment must be isolated
from the mains before powering the board. When using an
oscilloscope with the demonstration board, it must be
isolated from the AC line. This prevents shock from occurring
as a result of touching any SINGLE point in the circuit, but
does NOT prevent shock when touching two or more points
in the circuit. Do not touch the demonstration board after
disconnection from the voltage supply; several parts and
power terminals, which contain energized capacitors, must
be allowed to discharge.
All operations involving transportation, installation and use, as well as maintenance, are to
be carried out by skilled technical personnel (national accident prevention rules must be
observed). For the purpose of these basic safety instructions, “skilled technical personnel”
are considered as suitably qualified people who are familiar with the installation, use, and
maintenance of power electronic systems.
1.3.2 Demonstration board intended use
The STEVAL-IHM027V1 demonstration board is designed for demonstration purposes only
and must not be used for any commercial purposes. The technical data, as well as
information concerning power supply conditions, must be taken from the relevant
documentation and strictly observed.
1.3.3 Demonstration board installation
The installation of the demonstration board must be in accordance with the specifications
and the targeted application.
●The boards contain electro-statically sensitive components that are prone to damage
through improper use. Electrical components must not be mechanically damaged or
destroyed
●Avoid any contacts with other electronic components
●During the motor drive converters must be protected against excessive strain. In
particular, no components are to be bent or isolating distances altered during the
course of transportation or handling
