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.
