MANUAL CHANGE INFORMATION
The date code at the bottom of each page of this manual reflects the creation or revision date.
Date codes are changed only on pages that have been revised and any following pages affected by
the revisions (i.e., pagination). If significant revisions are made to a section, the date code on all
pages of the section will be changed to reflect the revision date.
Each time revisions are made, both the main table of contents and the affected individual section
table of contents are regenerated and the date code is changed to reflect the revision date.
Changes in this manual to date are summarized below (most recent revisions listed at top).

20020426 This revision includes the following changes:
− Reissued Entire Manual.
− The changes in this revision relate to the new global setting PTCONN that
allows the relay to be configured for either wye- or delta-connected PTs; new
global setting VSCONN that allows the relay to be configured for a
synchronism check or broken delta voltage input to the VS-NS terminals; new
setting range VNOM = OFF that causes the relay to disregard the loss-of-
potential logic for direction elements that use zero-sequence voltage as a
polarizing source when VSCONN = 3V0; and the new three-phase power
elements (SEL-351-7 only).
Section 1:
− Updated Table 1.2.
− Added subsection: Potential Transformer Connections.
− Added voltage input notes to Figure 1.2.
− Added AC Input Voltage and Metering specifications for open-delta
connected PTs.
Section 2:
− Updated Figure 2.1 to include projection panel-mount option.
− Added subsection: Determining Voltage Input Rating.
− Added subsection: Wye-Connected Voltages (Global Setting PTCONN =
WYE).
− Added subsection: Delta-Connected Voltages (Global setting PTCONN =
DELTA).
− Added subsection: Synchronism Check VS Connection (Global setting
VSCONN = VS).
− Added subsection: Broken-Delta VS Connection (Global setting VSCONN =
3V0).
− Added subsection: Polarity Check for VSCONN = 3V0
