4.2 Meaning of connectors
The following charts show the meaning of the connectors of
the devices.
For further information look at chapter “TECHNICAL DATA”.
POWER
Power supply device (24 VAC/DC not isolated).
If the device is powered in direct current, it will be necessary
to respect the polarity of the power supply voltage.
If the device is connected to a devices network, it will be
necessary:
-
the power supply of the devices making the network is
galvanically isolated one another
- the phase supplying the device is the same supplying all
the devices making the network.
Part Meaning
AC/+ power supply device:
- if the device is powered in alternate current,
connect the phase
- if the device is powered in direct current, con-
nect the positive pole
AC/- power supply device:
-
if the device is powered in alternate current,
connect the neutral
- if the device is powered in direct current, con-
nect the negative pole

1 INTRODUCTION
1.1 Introduction
c-pro 3 NODE kilo+ is a range of programmable controllers for applications in refrigeration and air conditioning sectors.
The controllers have a considerable number of inputs and outputs; they allow to realize a flexible, modular and expandable
control devices network.
The variety of available communication ports (RS-485, CAN, USB and Ethernet) and supported communication protocols
make easier the integration of the devices in systems.
The application software can be realized through the UNI-PRO 3 development environment for programmable controllers.

Additional information for electrical connec-
tion
- do not operate on the terminal blocks of the device
using electrical or pneumatic screwers
- if the device has been moved from a cold location to a
warm one, the humidity could condense on the in-
side; wait about an hour before supplying it
- make sure the power supply voltage, the electrical
frequency and the electrical power of the device cor-
respond to those of the local power supply; look at
chapter “TECHNICAL DATA”
- disconnect the power supply of the device before serv-
icing it
3 SIZE AND INSTALLATION
3.1 Size
The following drawing shows the size of the devices (8 DIN modules); size is in mm (in).
2 DESCRIPTION
3.2 Installation
Installation is on DIN rail 35.0 x 7.5 mm (1.377 x 0.295
in) or 35.0 x 15.0 mm (1.377 x 0.590 in), into a switch-
board.
To install the devices operate as shown in the following
drawing. To remove the devices remove possible extractable screw ter-
minal blocks plugged at the bottom first, then operate on the
DIN rail clips with a screwdriver as shown in the following
drawing.
To install the devices again press the DIN rail clips to the end
first.
3.3
Additional information for the installation
- make sure the working conditions of the device (operat-
ing temperature, operating humidity, etc.) are in the limits
indicated; look at chapter “TECHNICAL DATA”
- do not install the device close to heating sources (heat-
ers, hot air ducts, etc.), devices having big magnetos
(big speakers, etc.), locations subject to direct sunlight,
rain, humidity, dust, mechanical vibrations or bumps - according to the safety legislation, the protection against
possible contacts with the electrical parts must be en-
sured by a correct installation of the device; all the parts
which ensure the protection must be fixed so that you
can not remove them if not by using a tool.
