The insulation values (air gaps and creepage distances) are sized for the fo-
llowing ambient conditions in accordance with EN 61010-1:2010:
EN
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 compo-
nents) was tested with a reduced impact energy of 2 J corresponding to IK07
per EN 61010-1:2010. The IK code is included on the respective product label.
