6.11.2 Programming Settings
General Voltage protection is only in effect and accessible if address  is set to
(QDEOHG during configuration of protective functions. If the voltage protection function
is not needed, address  should be set to 'LVDEOHG.
All setting values are based on phase-to-phase voltages. The setting ranges depend
on the type of voltage transformer connection utilized (specified at address ). For
voltage transformers connected in a grounded-wye configuration, higher setting val-
ues may be used because the voltage inputs are subjected only to phase-to-ground
voltage levels.
