TPS 320i /nc
1) Interface to a 230/400 V, 50 Hz public grid
2) A Class A equipment is not intended for use in residential locations where the elec-
trical power is provided by the public low-voltage supply system.
There can be potential difficulties in ensuring electromagnetic compatibility in those
locations, due to conducted as well as radiated radio-frequency disturbances.
