I
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.
• Cover or enclose neighbouring units
that are live.
• Follow the engineering instructions
IL (previously AWA) of 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) must be
connected to the protective earth
(PE) or to the potential equalisation.
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.
• Suitable safety hardware and
software measures should be
implemented for the I/O interface
so that a line or wire breakage on
the signal side does not result in
undefined states in the automation
devices.
• Ensure a reliable electrical isolation
of the low voltage for the 24 volt
supply. Only use power supply
units complying with IEC 60364-4-
41 (VDE 0100 Part 410) or HD
384.4.41 S2.
• 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 restart.
• Devices that are designed for
mounting in housings or control
cabinets must only be operated and
controlled after they have been
installed with the housing closed.
Desktop or portable units must only
be operated and controlled in
enclosed housings.
Eaton Industries GmbH Safety instructions
Danger!
Dangerous electrical voltage!

II
• 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 damage to
persons or property, 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.).

1.1 Introduction
NZM-XMC Measuring and Communication Module 11/16 MN01219001Z-EN www.eaton.com 5
1 Device overview
1.1 Introduction
The NZM...-XMC-... range covers measuring devices for electrical variables in
three-phase systems. It is designed with a new mounting and installation
concept.
The energized cables are passed through the device. Punch screws are used
to fasten the device to the cables and the voltage is measured.
Actual values, minimum values and maximum values can be measured and
output over a specified period for currents, voltages and power.
The measuring and communication modules can be used flexibly within a
voltage range of 35 V to 600 V and a current range of 1.5 to 500 A (or up to
630 A in conjunction with a mounting kit).
The NZM...-XMC-...measuring and communication module can be mounted
at any location inside a cabinet. Alternatively the device can be fixed to a
mounting plate.
The system can be used regardless of the design and type of circuit-breaker
involved.
All existing circuit-breakers and switch-disconnectors can be used. Only the
minimum clearance of the circuit-breaker must be taken into account for
mounting.
Once
properly installed on wires or buss bars, the device withstands weights
up to 75 kg.

1.2 Device types
6NZM-XMC Measuring and Communication Module 11/16 MN01219001Z-EN www.eaton.com
1.2 Device types
Two sizes of NZM…-XMC-… measuring modules are available and are
matched to the current ranges of circuit-breaker NZM.
•Construction size 2 (NZM2-XMC-MB-250) for currents up to 250 A
•Construction size 3 (NZM3-XMC) for currents up to 600 A
Both
sizes are available in 3 pole (NZM...-XMC-...) or 4 pole (NZM…-4-XMC-…)
versions.
One version is provided with a digital S0 output (see also the note on page 7)
and another version is provided with a MODBUS interface and display
interface. A total of ten types (basic devices) of NZM-XMC measuring and
communication modules are available.
In addition, a universal measuring module (NZM-XMC-TC-MB) for external
transformer connections (transducer) is also available. The data for this
module is compatible with that of the above basic devices to a large extent,
and the module provides a large degree of flexibility in terms of the desired
current range. The device is powered with a 230 VAC voltage.
In addition, a mounting kit (NZM-XMC-KIT-630) for a maximum current of
630 A and a LED display (NZM-XMC-DISP) used to show readings are
available.
