 For a three-conductor system, you must insert the 2-pin connector provided
with the 2-pin connection jumper in the socket.
 For a four-conductor system with neutral conductor, you must insert the con-
nector without jumper and connect the connection pin marked "N" with the
neutral conductor busbar using a 1.5 mm² cable.
4.2.2 Assembly with the tap-off at the top (only size NH00)
The NH measurement module of size NH00 can also be assembled with the tap-
off at the top on the NH fuse-switch disconnector. For this assembly, the meas-
urement module is installed turned through 180° and so L1 and L3 exchanged.
 Set this in the configuration in order to adapt the representation of the meas-
ured values appropriately (via ModBus, CMC III PU or USB).
4.3 Operation
The NH measurement module acquires the values specified in the technical
specifications (see section 8.4 "Measured values") and stores them in the internal
memory. The data can be fetched via the USB interface (see section 4.5 "Access
Note:
Appropriate conductor protective terminals are described in the
"RiLine accessories" area of the current Rittal manual.

the CMC III PU via CAN bus (see section 4.7 "CMC III (CAN bus)") and via Mod-
Bus RTU (see section 5 "ModBus").

4.3.2 Activating the NH measurement module
The NH measurement module switches the power supply on automatically. The
power can be supplied in two ways that are not mutually exclusive:
1. Self-supply via the phases L1–L2
2. Supply from the CMC III Processing Unit via the CAN bus
The power can be supplied via the CAN bus. 24 VDC is present at pins 3 and 6,
GND is present at pins 4 and 5. Whereby, it suffices to assign pins 3 and 4. The
Note:
Check whether you operate the NH measurement module with 3 or
4 conductors. In 3-conductor operation, the L2 and N inputs must
be jumpered (see section 4.3.1 "Control and display components").
In 4-conductor operation, the neutral conductor must be connect-
ed to connection 2 (see section 4.3.1 "Control and display compo-
nents"). For this purpose, use the provided connector with only one
installed contact in order to prevent a connection fault. The exact
connection is shown in the assembly instructions (see section 4.2
"Assembly"). The associated operating mode must be set in the
configuration via USB, CMC III PU, ModBus or the LCD display for
monitoring.
Note:
Power supply via ModBus is not possible.

power supply unit for ModBus and the display with provided adaptor cable offers
a plug-and-play solution.
4.3.3 LED displays
The NH measurement module uses two LEDs for the status display. The com-
munications and operating states are signalled.
In the normal state, CAN bus (LED 1) and ModBus communication (LED 2) is dis-
played with the LEDs.
The LEDs for fault messages are used for warnings, alarms, temperature and
limit value violations (for the NH measurement module).
For USB communication, the LEDs are used for the associated status messag-
es.
Faults in the USB communication are displayed as follows.
Note:

quires phases L1 and L2. Please observe, in particular, the auto-
mated sequences.

4.3.4 De-energising
The electronics of the NH measurement module can be de-energised, for exam-
ple, for any high-voltage inspections.
 Ensure that the plant is switched off.
 Remove the cover.
 Pull the lower part of the NH measurement module with the communications
connections downwards.
Warning!
If the NH measurement module is connected, the electronics
can be loaded to maximum 4 kV. The de-energisation de-
scribed in the following steps permits a maximum loading of
6kV.

 Re-assemble the contact hazard protection cover.
 Ensure that the other end of the USB adaptor present in the cover is connect-
ed to the NH measurement module.
The electronics are now de-energised and the NH measurement module can be
loaded with maximum 6 kV.
 Proceed in the reverse order to reconnect the measurement electronics.

4.4 Configuration files
4.4.1 General information
The basic configuration of the NH measurement module is performed as stand-
ard via the USB interface. This is not allowed when you use the NH measurement
module with a CMC III PU. Configuring via ModBus is also possible.
The configuration is made with three different configuration files as described be-
low.
The files generated by the unit at the first start or after deletion by the user have
the following file names:
– Alarm configuration: ALARM.CNF
– Logging configuration: LOGGING.CNF
– System configuration: SYSTEM.CNF
In addition to these file names, the following file names are also supported:
– ALA*.CNF or ALA*.cnf
– LOG*.CNF or LOG*.cnf
– SYS*.CNF or SYS*.cnf
This permits the free assignment of maximum five characters, for example, for
versions or for differentiation of the configuration for the various NH measure-
ment modules.
The file for alarm configurations contains the values for alarms and warnings.
This configuration is limited to seven different groups of alarms/warnings directly
associated with the measured values.
The logging interval and the list of the values to be logged are specified by the
logging configuration. The values are stored in the non-volatile data memory
of the NH measurement module. If no (valid) logging configuration file is found,
the logging starts with the default logging setting.
The system configuration contains the basic configuration of the NH measure-
ment module, such as bus addresses.
A comment can be added to the configuration files with the commentary opera-
tor "//".
A line break must follow the last parameter to be interpreted; this means that the
last line is empty.
4.4.2 File structure
Note:
The time of day for the USB logging can be set via ModBus or the
display available as accessory.
clic!

Rittal NH measurement module 19
4 NH measurement module installation and operation
EN
The NH measurement module is equipped with a local FAT16 file system on flash
memory. This memory is used to save the configuration, log and firmware update
files. The file names are limited to 8.3, this means:
– The file name may contain maximum 8 alphanumeric characters (uppercase
and lowercase alphabetic characters and numbers).
– A full stop and the extension with exactly 3 characters then follows.
The flash memory is divided into two partitions with the following file structure:

The "\CONFIG" folder contains the configuration files of the NH measurement
module. All configuration files can be identified with their extension *.CNF (or
*.cnf).
The NH measurement module generates these files with the current settings in
ANSI format. Format UTF-8 is also supported for a configuration.
4.4.3 Serial number
A serial number must always be specified for the configuration files. This number
can be found on the type plate (see section3.5 "Serial number") or in the config-
uration files generated by the measurement block. All configuration files must
contain a line in the following format:
– SERIAL;XxXxXxXxXx (10-digit numeric serial number)
If this line is missing, the configuration file will not be accepted by the NH meas-
urement module.

Note:
It is possible to enter 0000000000 (10x "zeroes") as placeholder in
each configuration file. This configuration file will be accepted by
every NH measurement module. Use this function with care!

All values must be entered with factor 100 or with exactly 2 decimal places, but
without decimal point. The hysteresis specified as percentage value ("%") is an
exception.
Example:
The NH measurement module should issue a warning for a voltage violation of
410.32 volts. This is achieved with the following input: "UWH;41032".
The following table describes all configuration parameters. In this case, depend-
ing on the NH measurement module variant, the nominal current

is 150 A,
