Nissei DSK-1031 Instruction Manual page 12

DSK-1031 is intended for use in the electromagnetic environment specifi ed below. The customer or the user of DSK-1031 should assure that it is used in such an environ-
ment.

Compliance level Electromagnetic environment – guidance
±6 kV contact Floors should be wood, concrete or ceramic tile. If fl oors are
±8 kV air covered with synthetic material, the relative humidity should
be at least 30 %.
±2 kV for power supply lines Mains power quality should be that of a typical commercial
±1 kV for input/output lines or hospital environment.
±1 kV diff erential mode Mains power quality should be that of a typical commercial
±2 kV common mode or hospital environment.
<5% U (>95% dip in U ) for 0,5 Mains power quality should be that of a typical commercial
