M-Max frequency converters are divided into three voltage
categories:
• 100 V (MMX11)
• 200 V (MMX12..., MMX32...)
• 400 V (MMX34...)

Mains 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 (e.g. 230 V, 400 V).
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: 120 V l 115 V, 240 V l 230 V,
480 V l 460 V.
The wide tolerance range of frequency inverter M-Max
into account a permissible voltage drop of an additional 4 %
(U - 14 %) in load networks, while, in the 400 V category, it
LN
takes into account the North American line voltage of
480 V +10 % (60 Hz).
The permissible connection voltages for the M-Max
listed in the Technical Specifications section in the appendix.
The rated operational data of the mains voltage is always based
on the mains frequencies 50/60 Hz (50 Hz -10 % - 60 Hz +10 %).

Units

Every physical dimension included in this manual uses interna-
tional metric system units, otherwise known as SI (Système Inter-
national d'Unités) units. For the purpose of the equipment's UL
certification, some of these dimensions are accompanied by their
equivalents in imperial units.
