Environmental conditions
Warning about dangerous electrical voltage! Danger to life - Danger of electric shock!
Overvoltage category III (test voltage 4.0 kV) / contamination degree 2: All connections of the
device provided for operation with 230 V AC supply voltage must be wired with the same phase
conductor. 400 V AC between neighbouring connection terminals is not permitted!
Overvoltage category II (test voltage 2.5 kV) / contamination degree 2 or
overvoltage category II (test voltage 2.5 kV) / contamination degree 1: Different phase conductors
may be used. 400 V AC between neighbouring connection terminals is permitted!
