Safety
Definitions and symbols
VOLTAGE
This symbol indicates high voltage. It calls your attention to items
or operations that could be dangerous to you and other persons
operating this equipment. Read the message and follow the
instructions carefully.
This symbol is the “Safety Alert Symbol.” It occurs with either of
two signal words: CAUTION or WARNING, as described below.
WARNING
Indicates a potentially hazardous situation which, if not avoided,
can result in serious injury or death.
CAUTION
Indicates a potentially hazardous situation which, if not avoided,
can result in minor to moderate injury, or serious damage to the
product. The situation described in the CAUTION may, if not
avoided, lead to serious results. Important safety measures are
described in CAUTION (as well as WARNING).
Hazardous high voltage
VOLTAGE
Motor control equipment and electronic controllers are connected
to hazardous line voltages. When servicing drives and electronic
controllers, there may be exposed components with housings or
protrusions at or above line potential. Extreme care should be taken
to protect against shock.
Stand on an insulating pad and make it a habit to use only one
hand when checking components. Always work with another
person in case an emergency occurs. Disconnect power before
checking controllers or performing maintenance. Be sure
equipment is properly grounded. Wear safety glasses whenever
working on electronic controllers or rotating machinery.

Cautions and notices
Read this manual thoroughly and make sure you understand the procedures before you
attempt to install, set up, or operate Eaton’s M-Max Series adjustable frequency drive.
Cautions
CAUTION
Be ABSOLUTELY sure not to connect two functions to one and
same output in order to avoid function overruns and to ensure
flawless operation.
CAUTION
The calculated model does not protect the motor if the airflow to
the motor is reduced by blocked air intake grill.
Notices
Notice
The inputs , unlike the outputs , cannot be changed in RUN state.
Danger and dangerous electrical voltage
Before commencing the installation
Disconnect the power supply of the device.
Ensure that devices cannot be accidentally restarted.
Verify isolation from the supply.
Earth and short circuit the device.
Cover or enclose any adjacent live components.
Follow the engineering instructions IL04020001E for the device
concerned.
Only suitably qualified personnel in accordance with EN 50110-1/-2
(VDE 0105 Part 100) may work on this device/system.
Before installation and before touching the device, ensure that you
are free of electrostatic charge.
The functional earth (FE, PES) must be connected to the protective
earth (PE) or the potential equalization. The system installer is
responsible for implementing this connection.
Connecting cables and signal lines should be installed so that
inductive or capacitive interference does not impair the automation
functions.
Install automation devices and related operating elements in such a
way that they are well protected against unintentional operation.

MN04020002E
February 2010
Suitable safety hardware and software measures should be
implemented for the I/O interface so that an open circuit on the
signal side does not result in undefined states in the automation
devices.
Ensure a reliable electrical isolation of the extra-low voltage of the
24V supply. Only use power supply units complying with IEC 60364-
4-41 (VDE 0100 Part 410) or HD384.4.41 52.
Deviations of the mains voltage from the rated value must not
exceed the tolerance limits given in the specifications, otherwise
this may cause malfunction and dangerous operation.
Emergency stop devices complying with IEC/EN 60204-1 must be
effective in all operating modes of the automation devices.
Unlatching the emergency-stop devices must not cause a restart.
Devices that are designed for mounting in housings or control
cabinets must only be operated and controlled after they have been
installed and with the housing closed. Desktop or portable units
must only be operated and controlled in enclosed housings.
Measures should be taken to ensure the proper restart of programs
interrupted after a voltage dip or failure. This should not cause
dangerous operating states even for a short time. If necessary,
emergency-stop devices should be implemented.
Wherever faults in the automation system may cause injury or
material damage, external measures must be implemented to
ensure a safe operating state in the event of a fault or malfunction
(for example, by means of separate limit switches, mechanical
interlocks, etc.).
Depending on their degree of protection, frequency inverters may
contain live bright metal parts, moving or rotating components, or
hot surfaces during and immediately after operation.
Removal of the required covers, improper installation or incorrect
operation of motor or frequency inverter may cause the failure of
the device and may lead to serious injury or damage.
The applicable national accident prevention and safety regulations
apply to all work carried on live frequency inverters.
The electrical installation must be carried out in accordance with
the relevant regulations (e.g., with regard to cable cross sections,
fuses, PE).
Transport, installation, commissioning and maintenance work must
be carried out only by qualified personnel (IEC 60364, HD 384 and
national occupational safety regulations).
Installations containing frequency inverters must be provided with
additional monitoring and protective devices in accordance with
the applicable safety regulations. Modifications to the frequency
inverters using the operating software are permitted.

Rated operational data on the nameplate
The device-specific rated operational data for M-Max Series adjustable frequency drives
is shown on the nameplate on the device's side and on the back of the control signal
terminal cover.
The inscription of the nameplates has the following meaning (example):
Table 1: Nameplate Inscriptions
Mains voltages
The given rated operational voltages in Table 2 are based on the standardized rated values in
centrally earthed star networks.
In ring-type networks (e.g., Europe) the rated voltage corresponds the value of the consumer
networks (e.g., 230V, 400V) at the utility company’s transfer point.
In star-type mains (e.g., North America) the rated voltage at the utility company’s transfer
point is higher than in the consumer network. For example: 120V  115V, 240V  230V,
480V  460V.
