WARNING
Explosion of the Y capacitors
If you operate units, category C1, C2 or C3 (radio interference suppression class A or B)
with type designation "2T..-.....-....A/B...." on ungrounded mains power supplies, then this
can destroy the Y capacitors at the line supply input. Serious injury and death can occur.
Only use units without RFI suppression filter with the type designation "2T..-.....-....O...." on
an ungrounded mains power supply. IT mains power supplies are not grounded.
