Connection
1.
NOTE! Lead the 230 V supply voltage
to the device through a double-pole
switch. Connect the supply voltage
to connectors N and L in the electron-
ics section of the terminal device, as
shown in Figures 2.1–2.3.
2.
Connect the ground to the terminal device’s
separate ground connector as shown in
Figures 2.1–2.3.
3.
Connect the ECO series terminal device to
the controller with the Modbus cable as shown
in Figures 2.1–2.3.
4.
Connect the bus cables as shown in the figures.
5.
Activate the termination resistor by moving
the termination jumper to the ON position in
the first and last device of the bus.
NOTE! Electrical connections may only
be made by a professional electrician.
WARNING! The supply air device carries
a voltage of 230 V.
