AC Input voltage: 100 ~ 240V AC, 48 ~ 63Hz, 
auto selection.  Power consumption: 96VA. 
  Connect the protective grounding conductor of 
the AC power cord to an earth ground, to avoid 
electrical shock. 
  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. 
  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 
(Pollution Degree) EN 61010-1:2001 specifies the pollution degrees 
and their requirements as follows. The GDS-2000A 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.
