Proper use
The Energy Meter 610/610-PB is intended for the measurement
and calculation of electrical parameters such as voltage, current,
power, energy, harmonics etc. in building installations, on distribu-
tion units, circuit breakers and busbar trunking systems.
The Energy Meter 610/610-PB is suitable for integration into xed
and weatherproof switch panels. Conductive switch panels must
be earthed. Can be installed in any attitude.
Measured voltage and measured current must derive from the
same network.
The measurement results can be displayed and can be read out
and further processed via the interfaces.
The voltage measurement inputs are designed for measurements
in low voltage networks, in which rated voltages of up to 300 V
relative to earth and surges in overvoltage category III can occur.
The current measurement inputs of the Energy Meter 610/610-PB
are connected via external ../1A or ../5A current transformers.
The measurement in medium and high voltage networks is im-
plemented in principle via current and voltage transformers. The

Current measurement via I1 to I4
The Energy Meter 610/610-PB is designed to have current trans-
formers with secondary currents from ../1A and ../5A attached cia
terminals I1-I4. The factory default for the current transformer ratio
is 5/5A and must be adapted to the current transformer employed
if necessary.
Direct measurement without a current transformer is not possible
using the Energy Meter 610/610-PB.
Only AC currents can be measured - DC currents cannot.
Via the current measurement input I4 only an apparent current
measurement is carried out thanks to the lack of a multiplier. Pow-
er measurements are therefore not possible using the I4 input.

touch.

Earthing of current transformers!
If a connection is provided for the earthing of second-
ary windings then this must be connected to the earth.
Caution!
The Energy Meter 610/610-PB is not suitable for meas-
uring DC voltages.
It is not necessary to congure a connection schematic
for the I4 measurement input.
Direction of the current
The current direction can be individually corrected on the device or
via the serial interfaces for each phase.
In the case of incorrect connection, the current transformer does
not need to be subsequently reconnected.
Caution!
The Energy Meter 610/610-PB is only approved for a
current measurement using the current transformer.
Current transformer connections!
The secondary connection of the current transformer
must be short-circuited on this before the current feed
to the Energy Meter 610/610-PB is disconnected!
If a test switch, which automatically short-circuits the
secondary wires of the current transformer, is avail-
able then it is sufcient to set this to the “Test” position
insofar as the short-circuiting device has been checked
beforehand.
Open-circuit current transformers!
High voltage spikes that are dangerous to touch can
occur on current transformers that are driven with
open-circuit secondary windings!
With “safe open-circuit current transformers” the wind-
ing insulation is rated such that the current transformer
can be driven open. However, even these current
transformers are dangerous to touch when they are
driven open-circuit.

Total current measurement
If the current measurement takes place via two current transform-
ers, the total transformer ratio of the current transformer must be
programmed in the Energy Meter 610/610-PB.

Example:
The current measurement takes place via two current trans-
formers. Both current transformers have a transformer ratio of
1000/5 A. The total measurement is performed with a 5+5/5 A total
current transformer.
The Energy Meter 610/610-PB must then be set as follows:
Primary current: 1.000 A + 1.000 A = 2.000 A
Secondary current: 5 A
Ammeter
If you want to measure the current not only with the Energy
Meter 610/610-PB but also with the ammeter, the ammeter must
be connected in series with the Energy Meter 610/610-PB.

Shielding
A twisted and shielded cable must be provided for connections via
the RS485 interface.
• Ground the shields of all cables that run into the cabinet at the
cabinet entry.
• Connect the shield so it has a large contact area and conduc-
tively with a low-noise earth.
• Mechanically trap the cable above the earthing clamp in order to
avoid damage from cable movement.
• Use the appropriate cable inlets, e.g. PG screw joints, to insert
the cable into the switch cabinet.
Cable type
The cable used must be suitable for an ambient temperature of at
least 80 °C.
Recommended cable types:
Unitronic Li2YCY(TP) 2x2x0.22 (Lapp cable)
Unitronic BUS L2/FIP 1x2x0.64 (Lapp cable)
Maximum cable length
1200 m with a baud rate of 38.4 k.

Installation
Bus structure
• All devices are connected in a bus structure (line) and each de-
vice has its own address within the bus (also see programming
parameters).
• Up to 32 stations can be interconnected in one segment.
• The cable is terminated with resistors (bus termination, 120 ohm
1/4 W) at the beginning and end of a segment.
• If there are more than 32 stations, repeaters (line ampliers)
must be used in order to connect the individual segments.
• Devices with activated bus termination must be supplied with
power.
• It is recommended to set the master at the end of a segment.
• The bus is inoperative if the master is replaced with an activated
bus termination.
• The bus can become unstable if the slave is replaced with an
activated bus termination or is dead.
• Devices that are not involved in the bus termination can be ex-
changed without making the bus unstable.
• The shield has to be installed continuously and needs to be
broadly and well conducting connected to an external low volt-
age (or potential) ground at the end.

USB interface
The Universal Serial Bus (USB) enables a rapid and uncompli-
cated connection between the device and a computer. After the in-
stallation of the USB driver the device data can be read out via the
ecoExplorer go software and rmware updates can be installed.
The USB2.0 connection cable with A/B connectors included in the
scope of deliverables is required for the USB connection of the
device to the USB interface of the computer.
USB A/B PC
The cable length of the USB connection should not
exceed 5 m.

Probus interface (only Energy Meter 610-PB)
This 9-pin D-sub receptacle RS485 interface supports the Probus
DP V0 slave protocol.
For the simple connection of inbound and outbound bus wiring
these should be connected to the Energy Meter 610-PB via a
Probus connector.

Fig.: Energy Meter 610-PB with D-sub receptacle for Probus
(View on rear).
The device address can be congured by using the pa-
rameter 000 if the device is used in a Probus-System.
The baud rate in a Probus system is detected auto-
matically and must NOT be set via the address 001!
Connection of the bus wiring
The inbound bus wiring is connected to terminals 1A and 1B of the
Probus connector. The continuing bus wiring for the next device
in line should be connected to terminals 2A and 2B.
If there are no subsequent devices in the line then the bus wiring
must be terminated with a resistor (switch to ON).
With the switch set to ON terminals 2A and 2B are switched off for
further continuing bus wiring.

Digital outputs
The Energy Meter 610 and Energy Meter 610-PB have 6 digital
outputs, whereby these are split into two groups of 2 and 4 outputs.
Digital outputs, Group 1
• The status indicator appears on the display at K1 or K2
• The status indicator on the display is not dependent on an inver-
sion being activated (NC / NO)

Fig.: Connection digital/pulse outputs
These outputs are electrically isolated from the evaluation elec-
tronics by optocouplers. The digital outputs have a common refer-
ence.
• The digital outputs can switch DC and AC loads.
• The digital outputs are not short circuit protected.
• Connected cables longer than 30 m must be shielded.
• An external auxiliary voltage is required.
• The digital outputs can be used as pulse outputs.
• The digital outputs can be controlled via the Modbus.
• The digital outputs can output results from comparators
When using the digital outputs as pulse outputs the
auxiliary voltage (DC) must have a max. residual rip-
ple of 5 %.
Functions for the digital outputs can be adjusted clearly
in the ecoExplorer go software. A connection between
the Energy Meter 610/610-PB and the PC via an in-
terface is required for the use of the ecoExplorer go
software.
