Power Supply
WARNING

AC Input voltage: 100 - 240V AC, 50 - 60Hz,
auto selection. Power consumption:
100W for
GDS-3000A series.

Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid
electrical shock.
Cleaning the
GDS-3000A
Series

Disconnect the power cord before cleaning.

Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.

Do not use chemicals containing harsh materials
such as benzene, toluene, xylene and acetone.
Operation
Environment

Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)

Relative Humidity: ≤80%, 40°C or below;
≤
45%,
41°C ~ 50°C

Altitude: < 2000m

Temperature: 0°C to 50°C
Note
(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The GDS-3000A series falls 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.
