Two external antennas (2,4 GHz IEEE802.15.4 and GSM) are connected to ECO603’s SMA connectors. The
antennas should be located outside the distribution board in as open a space as possible, e.g. on the top
or side of the board. For efficient operation, the antennas should be mounted onto a metal surface or
base. NOTE! The location of the antennas has a significant impact on reception.
The maximum control relay current, at a voltage of 230 VAC, is 10 A when the load is resistive.
NOTE! All
relays must be connected to the same phase. Intermediate relays must be used for connecting loads. Relay
contacts are potential-free.
Connect the measuring device ECO602.2 to the system by connecting ECO603’s pins BUS/A, BUS/B and
GND to the corresponding measuring device pins. Connect the power supply to the system by connecting
the positive and negative terminals of ECO603 to the positive and negative terminals of the power supply.
If the backup power supply ECO605 (accessory) is used, connect the positive and negative terminals of
the ECO603 to the positive and negative OUT terminals of the ECO605 and the positive and negative IN
terminals of the ECO605 to the positive and negative terminals of the power supply. Connect the supply
voltage to the terminals N and L of the power supply. See the wiring diagram on page 62.
Installing the ECO602.2
The ECO602.2 is a measuring device. The device is designed for installation onto a DIN rail in an electricity
distribution board, or into an enclosed space near the board, in such a way that a user cannot touch the
connectors and screw heads. A safety distance of 25 mm is required between the 12 VDC voltage supply
of the ECO602.2 measuring device and the live 230 VAC parts of the power supply.
The ECO602.2 measuring device front panel has two LED indicators. The PWR indicator indicates that the
device is connected to a power source. The STATUS indicator indicates the state of a software uppdate.
PRG is a programming button to determine Modbus ID, in eSmart system it is configured as default.
Electricity consumption is measured with current transformers
installed around phase conductors L1, L2 and L3. Open the
current transformer with e.g. a screwdriver. Do not damage
the bracket. Place the transformer around the phase conduc-
tor and close it. Connect the transformers to the ECO602.2 pins
CT1, CT2 and CT3. Connect the positive and negative terminals
of the power supply to the positive and negative terminals of
the ECO602.2. See the wiring diagram on page 62.
Connecting the Water Meter
In order to connect a water meter to eSmart, it must be equipped with a pulse output that converts
the measured amount of water into pulses. Typically, the pulse output is a reed relay installed onto the
mechanical meter. Connect the pulse output to pins Pulse 1 and GND of the ECO602.2 according to the
wiring diagram on page 62 using e.g. a KLM 2x0.8 cable. You can use a shielded cable in locations with
interference.
As there are different pulse outputs, the information on what amount of water corresponds to one pulse
must be set in eSmart. This is done via the operating panel’s menu
Settings/Parameters/Pulse parame-
ters
. Set the desired value with the
+
and
–
buttons. The inner + and - buttons increase/decrease the value
by 1, the outer by 100 (see figure on page 50). A mechanical meter typically generates one pulse per 10
litres of water, in which case the set value should be 100 pulses/m3 (m3=1000L). Set the value and press

Connecting the District Heating Meter
In order to connect a district heating meter to eSmart, the meter must be equipped with a pulse output
that converts the measured amount of energy into pulses. The pulse output is typically an open collector
