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
