About this Manual
Input Supply Voltages
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 voltage at the
transfer point of the power supply companies is the same as
the value in the consumer networks (for example, 230V, 400V).
In star networks (as found in North America), the rated
voltage at the transfer point of the utility companies is higher
than in the consumer network. Example: 120V 115V,
240V 230V, 480V 460V.
Units
Every physical dimension included in this manual uses
imperial units. For the purpose of the equipment’s UL
certification, some of these dimensions are accompanied by
their equivalents in metric or Système International d’Unites
(SI) units.
2 M-Max Series Adjustable Frequency Drive MN04020003E—April 2011 www.eaton.com
The wide tolerance range of M-Max frequency inverters
takes into account a permissible voltage drop of an additional
4% (ULN –14%) in load networks, while, in the 400V
category, it takes into account the North American line
voltage of 480V +10% (60 Hz).
The permissible connection voltages for the M-Max series
are listed in “Appendix A”.
The rated operational data of the input voltage is always
based on the input frequencies 50/60 Hz (50 Hz –10% to
60 Hz +10%).
