3. Specifications
The insulation values (air gaps and creepage distances) are sized for the
following ambient conditions per EN 61010-1:2010.
■
Altitude up to 2,000 m
■
Overvoltage category II
■
Pollution degree 2
■
Relative humidity 0 ... 95 % non-condensing (per DIN 40040)
The strength of the measuring instruments (enclosing, non-metallic components)
was tested with a reduced impact energy of 2 J corresponding to IK07 in
accordance with EN 61010-1:2010. The IK code is included on the respective
product label.
