The DDS system is designed
to support phase-chassis
voltages under 300 V AC.
It must be ensured that there is
no voltages over the indicated
value if an isolating
transformer is not installed; i.e.
if the DDS system is
connected directly to mains or
through an auto-transformer.
Otherwise, protection
elements must be installed to
avoid reaching excessive
voltages.
