SAFETY INSTRUCTION

WARNING

Warning: Identifies conditions or practices that could result in injury or loss of life.

CAUTION

Caution: Identifies conditions or practices that could result in damage to GDS-2000 or to other properties.

Attention Refer to the Manual

SAFETY INSTRUCTION

This chapter contains important safety instructions that you must follow when operating or storing the demo board designed for GDS-2000 and GLA-

1000. For safety instructions regarding GDS and GLA, refer to their user manuals.

Safety Symbols

These safety symbols may appear in this manual.

GDS-2000 Series Training Manual

General Guideline

CAUTION

 Do not place any heavy object on the instruments.  Avoid severe impacts or rough handling that leads to

damaging the instruments.

 Do not discharge static electricity to the instruments.  Use only mating connectors, not bare wires, for the

terminals.

 Do not disassemble the instruments unless you are

qualified.

Power Supply

WARNING

 Input voltage: DC 5V  The power supply voltage should not fluctuate more

than 10%.

Operation Environment

 Location: Indoor, no direct sunlight, dust free, almost

non-conductive pollution (Note below)

 Relative Humidity: < 80%  Altitude: < 2000m  Temperature: 0°C to 50°C

(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees and their requirements as follows. GDS-2000 and the Training Kit fall under degree 2.Pollution refers to “addition of foreign matter, solid, liquid, or gaseous (ionized gases), that may produce a reduction of dielectric strength or surface resistivity”.

 Pollution degree 1: No pollution or only dry, non-conductive

pollution occurs. The pollution has no influence.

 Pollution degree 2: Normally only non-conductive pollution

occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.

 Pollution degree 3: Conductive pollution occurs, or dry, non-

conductive pollution occurs which becomes conductive due to condensation which is expected. In such conditions, equipment is normally protected against exposure to direct sunlight, precipitation, and full wind pressure, but neither temperature nor humidity is controlled.

Storage environment

 Location: Indoor  Relative Humidity: < 85%  Temperature: 0°C to 50°C
