The rated operating voltages stated in the following table are based on the
standard values for networks with a grounded star point.
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, 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 DC1 variable frequency drive's wide tolerance range takes into account a
permissible voltage drop of 10% (i.e. U
category, it takes into account the North American mains voltage of
480 V + 10 % (60 Hz).
The rated mains voltage operational data is always based on mains
frequencies of 50/60 Hz within a range of 48 to 62 Hz.
￫
The permissible power supply for the DC1 series can be found
in ￫ Section 1.4.3 "Features", page 17.
Every physical dimension included in this manual uses international metric
system units, otherwise known as SI (Système International d'Unités) units.
For the purpose of the equipment's UL certification, some of these
dimensions are accompanied by their equivalents in imperial units.
