Wiring instructions
The Thyristor unit could be susceptible to interferences lost by near equipments or by the power supply, for
this reason in accord to the fundamental practices rules is opportune take some precautions:
• The coil contactor, the relays and other inductive loads must be equipped with opportune RC filter.
• Use shielded bipolar cables for all the input and output signals.
• The signal cables must not be near and parallel to the power cables.
• Local regulations regarding electrical installation should be rigidly observed.
Use copper cables and wires rated for use at 75°C only.
For safety connect the heat-sink to the earth with his terminal
