* If safety-approved EMI suppression capacitors are operated with a DC voltage being above the specified AC voltage rating the given approvals are no longer valid (IEC 60384-14).
Furthermore the permissible pulse rise time du/dt (Fmax.) will be subject to a reduction according to
Fmax. = Fr x √2 x UAC / UDC
if the DC operating voltage UDC is higher than √2 x UAC
