Important warnings for safety
This chapter contains important information for the safety. The not observance of these instructions may
result in serious personal injury or death and can cause serious damages to the Thyristor unit and to the
components system included.
The installation should be performed by qualified persons.
The Thyristor unit are integral part of industrial equipments. When it is supply, the
Thyristor unit is subject to dangerous tensions.
•
Don't remove the protection Cover.
•
Don't use these unit in aerospace applications and/ or nuclear.
The nominal current corresponds to use at temperature not superior to 45°C.
•
The Thyristor unit must be mounted in vertical position and without obstruction above
and below to allow a good flow ventilation.
•
The hot air of one thyristor unit must not invest the unit positioned above.
•
For side by side placed leave a space of 15mm between the unit.
A suitable device must ensure that the unit can be electrically isolated from the supply, this
allows the qualified people to work in safety.
Protection (Protection, Protezione)
The unit have IP20 protection rating as defined by the specific international. Is necessary
consider the place of installation.
Earth (Terre, Messa a terra)
For safety, the Thyristor unit with isolated heat-sink must be connected to earth.
Earth impedance should be correspondent to local earth regulation. Periodically the earth
efficiency should be inspected.
Electronic supply (Alimentation électronique, Alimentazione elettronica)
The electronic circuit of the Thyristor unit must be supplied by dedicated voltage for all
electronic circuits and not in parallel with coil contactors, solenoids and other.
It's recommended to use a shielded transformer.
Electric Shock Hazard (Risque de choque électrique, Rischi di scosse elettriche)
When the Thyristor unit is energized, after the power supply is shut off, wait least a minute
for allow the discharge of the internal capacitors where there is a dangerous tension. Before
working, make sure that:
•
Only authorized personnel must perform maintenance, inspection, and replacement
operations.
•
The authorized personnel must read this manual before to have access to the unit.
•
Unqualified People don't perform jobs on the same unit or in the immediate vicinities.
