Warning - hazardous electrical voltage!
Danger of electric shock!
Overvoltage category III (test voltage 4,0 kV)
/ pollution degree 2:
All device connections designed for use with 230 V AC supply voltage
must
be connected to the same
phase conductor.
400 V AC between neighbouring connection terminals is
not
permitted!
Overvoltage category II (test voltage 2,5 kV)
/ pollution degree 2
or
Overvoltage category II (test
voltage 2,5 kV) / pollution degree 1:
Different phase conductors may be used. 400 V AC between neighbouring connection terminals is
permitted!
