Safety and operating instructions

2.3.1

General terms

Warning:

During assembly, testing, and 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 and damage to property, if the kit

or components are improperly used or installed incorrectly.

The kit is not electrically isolated from the AC/DC input. The

demonstration board is directly linked to the mains voltage.

No insulation has been placed between the accessible parts

and the high-voltage. All measurement 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 a shock from

occurring as a result of touching any single point in the

circuit, but does NOT prevent shocks when touching two or

more points in the circuit. Do not touch the demonstration

board after disconnection from the voltage supply, as several

parts and power terminals, which contain energized

capacitors, need to 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 suitably qualified people who are familiar with the installation, use and maintenance of

powered electronic systems.

2.3.2

Demonstration board intended use

The STEVAL-IHM023V2 demonstration board is a component designed for demonstration

purposes only and is not to be used for electrical installation or machinery. The technical

data as well as information concerning the power supply conditions should be taken from

the documentation and strictly observed.

2.3.3

Demonstration board installation

The installation and cooling of the demonstration kit boards must be in accordance with the

specifications and the targeted application.

●

The motor drive converters are protected against excessive strain. In particular, no

components are to be bent or isolating distances altered during the course of

transportation or handling.

●

No contact must be made with other electronic components and contacts.

●

The boards contain electro-statically sensitive components that are prone to damage

through improper use. Electrical components must not be mechanically damaged or

destroyed.
