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 600 V.
- Fan voltage supply is 230 VAC 50/60Hz Power consumption 14W.
Don't remove the plastic cover which provides adequate protection against electric shock.
Don't use this thyristor units 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 specialised personnel;
·
the authorised personnel must read this manual before to have access to the unit;
·
the access to the units must be denied to unauthorised 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 rating are in line with real needs.
·
If authorised personnel must measure voltage current etc. on units, take away rings and other jewels
from fingers and hands.
·
Authorised 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 unit has a polymeric plastic cover to compliance to International specification IP20. To understand if
IP20 protection is sufficient should be evaluated the installation place.
Open Type Equipment(équipment de type ouvert)..
Maximum surrounding air temperature 40°C(Temperature de l'air environnante maximum 40°C).
Earth(terre)
CD3000 series 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.
Electromagnetic compatibility (compatibilité électromagnétique)
Our thyristor unit have an excellent immunity to electromagnetic interferences if all suggestions contained in this
manual are respected.
Emissions (emission)
All thyristor switching at high speed generate some radiofrequency disturbance. CD3000 serie compliance with EMC
rules for CE mark. In many installations near electronic devices has not been noted problems. If radiofrequency
devices 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.
INSTALLATION AND WIRING INFORMATION
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 cover corresponds to that ordered.
Before to switch on the unit verify:
·
Load current equal or less than nominal
·
Main voltage equal or less than nominal
·
Remember to supply fan at 230V on 110A unit
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.
