Page 5: Important Warnings For Safety
1. 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. - Page 6 A “NOTE” marks a short message to alert you to an important detail. A “CAUTION” safety alert appears with information that is important for protecting your equipment and performance. Be especially careful to read and follow all cautions that apply to your application. A “WARNING”...
- Page 7 CAUTION: To avoid compromising the insulation, do not bend wire or other components beyond their bend radius specifications. CAUTION: Protect the power controller from high temperature, humidity and vibrations. CAUTION: The power controller warranty is void if the tested and approved fuses are not used. CAUTION: Only trained and authorized personnel should access and handle the internal electronics and they must follow proper electro-static prevention procedures.

Page 8: Maintenance
2. Maintenance In order to have a corrected cooling, the user must clean the heat-sink and the protective grill of the fans. The fre- quency of this servicing depends on environmental pollution. Also check periodically if the screw for the power cables and safety earth are tightened correctly (See Connection Diagram). -
Page 9: Introduction
3. Introduction A thyristor unit is semiconductor device which acts as a switch formed by two thyristors in ant parallel. To switch on the alternating current the input signal will be on and the thyristor will switch off at first Zero Crossing voltage with no input signal. -

Page 53: Bakeout In Function
16. Bakeout in function 16.1 What is heater bakeout? If a MgO-insulated heater element shuts down for a long period of time (or sits in storage), it can absorb moisture. If full power is applied, excessive current can damage the heater or blow fuses. The heater bakeout feature soft starts the load to remove moisture from the heater and prevent blown heaters and fuses. -
