Proper use
The M-MAX
TM
frequency inverters are not domestic appliances.
They are designed only for industrial use as system components.
The M-Max
TM
frequency inverters are electrical apparatus for
controlling variable speed drives with three-phase motors. They
are designed for installation in machines or for use in combination
with other components within a machine or system.
After installation in a machine, the frequency inverters must not be
taken into operation until the associated machine has been
confirmed to comply with the safety requirements of Machinery
Safety Directive (MSD) 89/392/EEC (meets the requirements of
EN 60204). The user of the equipment is responsible for ensuring
that the machine use complies with the relevant EU Directives.
The CE markings on the M-MAX
TM
frequency inverter confirm
that, when used in a typical drive configuration, the apparatus
complies with the European Low Voltage Directive (LVD) and the
EMC Directives (Directive 73/23/EEC, as amended by 93/68/EEC
and Directive 89/336/EEC, as amended by 93/68/EEC).
In the described system configurations, M-MAX
TM
frequency
inverters are suitable for use in public and non-public networks.
A connection to IT networks (networks without reference to earth
potential) is permissible only to a limited extent, since the device’s
built-in filter capacitors connect the network with the earth poten-
tial (enclosure). On earth free networks, this can lead to
dangerous situations or damage to the device (isolation moni-
toring required).
Observe the technical data and connection requirements. For
additional information, refer to the equipment nameplate or label
at the frequency inverter and the documentation.
Any other usage constitutes improper use.
h
To the output of the frequency inverter (terminals U, V, W)
you must not:
• connect a voltage or capacitive loads (e.g. phase
compensation capacitors),
• connect multiple frequency inverters in parallel,
• make a direct connection to the input (bypass).
