formation, it can result in personal damage and/
or damages to the product.
Any unauthorized change or use of this device
beyond the specified mechanical, electrical or
other operating limits can cause personal da-
mage and/or damage to the product.
Any such unauthorized change represents "mi-
suse" and/or "negligence" in the sense of gua-
rantee for the product and therefore makes the
guarantee covering possible consequential da-
mages void.
This device is to be exclusively operated and
maintained by a specialist.

vant training and experience, are capable of re-
cognizing risks and avoiding possible hazards
that can be caused when operating or servicing
the device.
When using the device, the necessary legal and
safety regulations should be considered additio-
nally for the respective application case.
Caution!
If the device is not operated according
to the operating manual, protection is
no longer ensured and the device may
cause dangers.
c

Goods-in Check
Correct and safe operation of this device is
subject to appropriate transportation, correct
warehousing, installation and assembly as well
as careful operation and maintenance. If it can
be assumed that safe operation without any
danger is no longer possible, the device must
be taken out of operation immediately and se-
cured against unintentional initialization.
Unpacking and packing must take place, with
the usual care without applying force and using
suitable tools. The devices must be checked for
perfect condition with visual tests.
It should be assumed that risk-free operation is
not possible if, for example:
• There is visible damage,
• it no longer works due despite the main sup-
ply being intact,
• has been subject to unfavorable conditions
(e.g. storage outside of the authorized climate
limits without adaptation to the room climate,
thawing etc.) over a longer period of time or
transport stresses (e.g. a fall from a height, in-
cluding without any visisble external damage
etc).
• Please check the delivered items for comple-
teness before starting with the installation of
the device. All supplied options and design versi-
ons are described on the delivery note.

Description
Description
Intended Use
The EM-PQ2500 is intended for measurements
in the building installation, on distributors, pow-
er switches and bus bars.
Measurement voltages and measurement cur-
rents must come from the same network.
The EM-PQ2500 is suitable for installation in
switch boards with a fixed, weather-protected
extradata.
The EM-PQ2500 can be used in 2, 3 and 4 sup-
ply networks and in TN and TT networks.
The current measurement inputs of the EM-
PQ2500 are connected using external ../1A or
../5A current transformers.
The measurement in medium and high-voltage
networks generally takes place using current
and voltage transformers.
The EM-PQ2500 can be used in residential and
industrial areas.
Measurement results can be displayed, saved
and read-out using serial interfaces for further
processing.

Description
Measurement Method
The EM-PQ2500 measures without any gaps
and calculates all effective values over a 200ms
Interval.
The EM-PQ2500 measures the real effective va-
lue (TRMS) of the voltages and currents applied
to the measurement inputs.
Operating Concept
You can program the EM-PQ2500 in several
ways and call up measurement values.
• Direct- on the device using 6 keys and the
display.
• Using the configuration and visualization soft-
ware EM-PQ VIS.
• Using the EM-PQ2500 homepagefor devices
with an Ethernet interface.
• Using the RS485 with the Modbus-protocol.
You can change and call up data with the help
of the Modbus address list (stored on the en-
closed data carrier).
Only operating the EM-PQ2500 using the integ-
rated display and the 6 keys is described in this
operating manual.
The EM-PQ VIS configuration and visualization
software and the homepage have their own "on-
line assistance“.

EM-PQ VIS configuration and
visualization software
The EM-PQ2500 can be programmed and read-
out with the EM-PQ VIS configuration and vi-
sualization software included in the scope of
supply. A PC must be connected using a serial
interface (RS485/Ethernet) to the EM-PQ2500.
EM-PQ VIS features
• Programming the EM-PQ2500.
• Configuration of recordings.
• Recordings read-out.
• Saving data in a database.
• Graphic presentation of measurement values.
• Programming specific applications for the cli-
ent.

Place of Installation
The EM-PQ2500 is suitable for installation in
fixed, weather protected switch boards. Con-
ducting switch boards have to be grounded.
Installation extradata
In order to achieve sufficient ventilation, the EM-
PQ2500 has to be installed vertically. The clea-
rance has to be at least 50mm at the top and
bottom and 20mm at the side.
Front Board Cutout
Cutout size: 138+0.8 x 138+0.8 mm
Failure to maintain the minimum clea-
rances can destroy the EM-PQ2500 at
high environmental temperatures!

Ethernet Connection
The EM-PQ2500's Ethernet connection is loca-
ted on the underside of the housing.
Depending on the bending radius of the Ether-
net cable and plug type, you must provide a
connection area beneath the EM-PQ2500.
The connection area beneath the EM-PQ2500
should not be less than 50 mm.

Fixing
The EM-PQ2500 is fixed into the switch board

Protective Wire Connection
Use a ring cable lug for connecting the protecti-
ve wire to the EM-PQ2500.
Supply Voltage
A supply voltage is required to operate the EM-
PQ2500. The type and level of the necessary
supply voltage is noted on the label.
Before applying the supply voltage, make sure
that the voltage and the frequency match the
details on the label!
The connection cables for the supply voltage
must be connected using a fuse. Use a UL/IEC
listed fuse (6A type C).

Voltage Measurement
Three-phase 4 conductor systems
The EM-PQ2500 can be used in three-phase
4 conductor systems (TN, TT network) with a
grounded neutral wire. The bodies of the elec-
trical system are grounded.
Three-phase 3 conductor systems
The EM-PQ2500 is only suitable for use in IT
networks with restrictions, because the measu-
rement voltage is measured against the housing
potential and the input impedance of the device
causes a leakage current against ground. The
leakage current can cause isolation monitoring
in IT networks to respond.
Connection variations with a voltage transfor-
mer are suitable for IT networks without any re-
strictions.

Voltage Measurement Inputs
The EM-PQ2500 has 4 voltage measurement
inputs (V1, V2, V3, V4).
Overvoltage
The voltage measurement inputs are suitable for
measurements in networks in which overvolta-
ges in the overvoltage category 600V CATIII can
occur.
Frequency
The EM-PQ2500 requires the rated frequency
for measuring and calculating measurement va-
lues.
The EM-PQ2500 is suitable for measurements
in networks with a rated frequency in the range
of 40Hz to 70Hz.

Installation
The following has to be considered when con-
necting the voltage measurement:
• A suitable separator is to be provided in order
to disconnect the EM-PQ2500 from the cur-
rent and voltage.
• The separator must be placed near to the
EM-PQ2500, labelled for the user and must
be easy to reach.
• Use UL/IEC authorized overcurrent protection
and isolators (10A type C) only.
• The overcurrent protection device must have
a nominal value calculated for the short-cir-
cuit current at the connection point.
• Measurement voltages and measurement
currents must come from the same network.
Warning!
The voltage measurement inputs on the
EM-PQ2500 are dangerous to touch!
c
Warning!
The EM-PQ2500 is not suitable for
measuring DC voltages.
Warning!
Voltages that exceed the authorized
network nominal voltages must be
connected using a voltage converter.
c
Warning!
The voltage measurement inputs may
not be used for voltage measurement
in SELV circuits (Safety Extra Low Vol-
tage).
