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.
