If failure of the pump may cause damage from flooding,
you could use those contacts to sound an alarm or
to shut off the dehumid (via low-voltage relay).


Does this mean there is a small voltage on them in the event of pump
failure? Should I tape them up separately?

Thanks,

No voltage; they connect to a switch operated
by the float arm. Tape separately as a matter of practice.
