Electronic connection

National accident prevention rules must be followed when working on the main power
supply with the power supply or power board in general.
The electrical installation must be completed in accordance with the appropriate
requirements (for example, cross-sectional areas of the conductors, fusing, PE
connections).
1.5

Demonstration board operation

An AC insulated and protected against overload and short-circuits is preferable during the
evaluation tests of the system (that is, in compliance with technical equipment and accident
prevention rules).
A proper load, able to dissipate – or in any case, absorb and reuse – the power delivered by
the system, must be used. In case of resistive and dissipative dummy loads, particular
attention should be paid to the temperature that the load may reach. Provide the needed
equipment to avoid hot surfaces and risk of fire during the tests (fan, water cooled load, etc).
Note: Do not touch the board and its components after disconnection from the voltage supply as
several parts and power terminals containing possibly energized capacitors must be given
time to discharge.
