Important warnings (Attention, Avvertenze importanti)
During the operations with units under tension, local regulations regarding electrical
installation should be rigidly observed:
•
Respect the internal safety rules.
•
Don't bend components to maintain insulation distances.
•
Protect the units from high temperature humidity and vibrations.
•
Don't touch components to prevent electrostatic discharges on them.
•
Verify that the size is in line with real needs.
•
To measure voltage current etc. on unit, remove rings and other jewels from fingers
and hands.
•
Authorized personnel that work on thyristor unit under power supply voltage must be
on insulated board
This listing does not represent a complete enumeration of all necessary safety cautions.
Electromagnetic compatibility
(Compatibilità électromagnétique, Compatibilità elettromagnetica)
Our thyristor units have an excellent immunity to electromagnetic interferences if all
suggestions contained in this manual are respected. In respect to a good Engineering
practice, all inductive loads like solenoids contactor coils should have a filter in parallel.
Emissions (Emission, Emissioni)
All solid-state power controllers emit a certain amount of radio-frequency energy because
of the fast switching of the power devices.
The CD Automation’s Thyristor unit are in accord with the EMC norms, CE mark.
In most installations, near by electronic systems will experience no difficulty with
interference. If very sensitive electronic measuring equipment or low-frequency radio
receivers are to be used near the unit, some special precautions may be required. These
may include the installation of a line supply filter and the use of screened (shielded) output
cable to the load.
