CAUTION
Thyristor units are used in power industrial equipment. When the thyristor unit is working, there are
on the unit the following voltages
-Maximum main supply voltage on power terminals up to 600V.
-Auxiliary supply 230-460Vac.
-Fan voltage 230Vac 50/60Hz Power consumption 14W.
Don't remove the plastic cover which provides adequate protection against electric shock.
Don’t use this thyristor in aerospace and nuclear application.
Electric Shock Hazard (Risque the choque électrique)
When thyristor unit has been connected to main supply voltage and is switched off, before to touch
it be secure that the unit is isolated and wait at least one minute to permit to discharge internal
capacitors. Thus be secure that:
•access to thyristor unit is only permitted to specialized personnel;
•the authorised personnel must read this manual before to have access to the unit;
•the access to the units must be denied to unauthorized personnel.
Important warnings(attention)
•Local regulations regarding electrical installation should be rigidly observed.
•Safety regulations must be rigidly observed.
•Don't bend components to maintain insulation distances.
•Protect the units from high temperature, humidity and vibrations.
•Don't touch components to prevent elettrostatichal discharges on them.
•Verify that all ratings are in line with real needs.
•If authorized personnel must measure voltage, current etc. on units, take away rings and other
jewels from fingers and hands.
•Authorized personnel working on thyristor unit under power supply voltage must work on insulated
board. Be secure that board is not connected to earth.
This listing does not represent a complete enumeration of all necessary safety cautions.

Protection(protection)
CD3000 thyristor family has a polymeric plastic cover in compliance to International specification
IP20. To understand if IP20 protection is sufficient should be evaluated the installation place where
the units are installed.
Open Type Equipment(équipment de type ouvert).
Maximum surrounding air temperature 40°C(Temperature de l’air environnante maximum 40°C).
Earth(terre)
CD3000 family has isolated heatsink. For safety connect the heatsink to earth to avoid shocks in
case that circuit board or thyristors lost insulation. Earth impedance should be correspondent to
local earth regulation. Periodically the earth efficiency should be inspected.
Electronic Supply(alimentation électronique)
CD3000 family electronic circuit should be supplied by dedicated voltage supply for all electronic
circuit but not in parallel with contactor's coil, solenoids and other inductive or capacitive loads. It's
recomme nded to use a shielded transformer.
Electromagnetic compatibility (compatibilité électromagnétique)
Our thyristor unit has an excellent immunity to electromagnetic interferences if all suggestions
contained in this manual are respected. In respect to a good Engineering practise, all inductive
loads like solenoids contactor coils should have a filter in parallel.
Emissions (emission)
All thyristor switching at high speed generate some radiofrequency disturbance. CD3000 serie
complies with EMC rules for CE mark. In many installations near electronic devices has not been
noted problems. If radiofrequency device at low frequency are used near the thyristor unit, some
precautions should be taken like line filters and shielded cables for input signal and for load cables.

1. Glossary
1.1 Terminology
V: voltage power supply.
I: the full circulating current in thyristor unit.
P: total load power.
1.2 Input signal
SSR: This input type is a square waveform generated by a temperature controller.
AN: Analog input.
IRS: Communication command.
1.3 Power feed back
Feedback: supply voltage fluctuation changes the power to the load. To overcome this effect the
voltage supplied to the load is measured and compared with power demand from controller, the error
signal is used to automatically hold the power at demanded level.
1.4 What is a thyristor unit
A thyristor unit is semiconductor device which acts as a switch formed by two thyristors in
antiparallel. To switch on the alternating current the input signal will be on and the thyristor will
switch off at first zero crossing voltage with no input signal. The benefits of thyristor units
compared with elettromechanical contactors are numerouses: no mooving parts, no maintenance
and capacity to switch very fast. Thyristors are the only solution to control transformers and
special loads that change resistance with temperature and with age.

4. Installation and wiring information
4.1 Identification of the unit
Before to install the CD3000S unit examine for damages or deficiencies. If any is
found, notify the carrier immediately. Check that the product features shown on
CD3000S identification label corresponds to that ordered.
An identification label provide all the informations regarding the factory settings of the unit. This
label is on the board inside the unit, as represented below:
4.2 Installation
CD3000S unit should be always mounted in vertical position to improve air cooling on
heatsink. Maintain minimum distances in vertical and in horizontal as below represented.
Don’t install in proximity of hot elements and near units generating electromagnetic
interferences.
When more units are mounted inside a cubicle provide air circulation as below represented.
Sometimes it is necessary to provide a fan to have better air circulation.

5.1 Removing the cover
To open the unit apply as follow.
For S9 and S10 sizes, you must open the cover to configure the unit and to view the fuses
For S14 size, you must open the cover to cable, to configure the unit and to view the fuses
Warning: this procedure can be done just by specialized personnel
CD3000S unit has isolated heatsink. For safety connect the heatsink to hearth using its
terminal with hearth symbol.
CD3000S can be susceptible to airborne interferences from near equipment or from interferences on
main supply, so a number of precautions must be taken.
•Contactors coils and chokes must have in parallel a RC filter and must be supplied with a different
voltage line.
•All input/output signal must use screened bifilar wires.
•Signal input and output must not routing in same cable try and must not be parallel.
•Local regulations regarding electrical installation should be rigidly observed.
