    POWERBLOCK NOTES:

    MOUNTING:
    Careful mounting of powerblocks on the heatsink is one of the most important requirements of reliable satisfactory application. The contact surfaces of powerblock and heatsink must be clean, free from contamination and damage. Finish and flatness of heatsink contact surface should be310mm. A thin and uniform film of interface thermal compound should be applied to contact surface of powerblock and heatsink. Fixing bolts have to be uniformly tightened with the specified mounting torque. Cross sections of busbars or cables have to be dimensioned so that heating up the powerblock will be avoided. This applies in particular for series connected fuses.

    MAINTENANCE:
    Powerblocks are maintenance-free. The assembly group should, however, be cleaned from time to time to ensure the insulation capability, the heat dissipation and thus the availability of the power converter.

    WARNING:
    Beryllium oxide is used in the powerblock assembly for insulation. Do not destroy the powerblock case because the beryllium oxide dust resulting from such action is hazardous if inhaled.
