The following abbreviations are used in this manual:
0.7 Mains supply voltages
The rated operating voltages stated in the following table are based on the
standard values.
In ring networks (as found in Europe) the rated operating voltage at the
transfer point of the power supply companies is the same as the value in the
consumer networks (e.g. 230 V or 400 V).
In star networks (as found in North America), the rated operating voltage at
the transfer point of the utility companies is higher than in the consumer
network.
Example: 120 V
→ 115 V, 240 V → 230 V, 480 V → 460 V.
The wide tolerance range of the DS7 soft starters allows for voltage drops of
10% and a voltage drop of additional 4 %, as well as an excess voltage of
10 % that are permissible in consumer supply networks.
The rated mains voltage operational data is always based on mains
frequencies of 50/60 Hz (50 Hz - 5 % – 60 Hz +5 %).
