SEL-749M Settings Sheets
Instructi on Manual
These settings sheets include the definition and input range for each setting in the relay. You can access the settings
from the relay front panel and the serial ports. For factory default settings see the
ACSELERATOR
®
SEL-5030
Software.
➤ Some settings require an optional module (see Section 4: Protection and Logic Functions for
details).
➤ Some of the settings ranges may be more restrictive than shown, because of settings
interdependency checks performed when new settings are saved (see Table 6.6).
➤ The settings are not case sensitive.
