SECTION 2: ADDITIONAL INSTALLATION DETAILS
I NTRODUCTION
This section describes additional SEL-351P Recloser Control installation details not covered in
the Installation section of the SEL-351P Quick-Start Installation and User’s Guide. Refer also
to Figure 6 in the guide.

Table SECTION 2: .1 shows the correspondence between output contact jumpers and the output
contacts they control. Figure 6 in the Communications section of the SEL-351P Quick-Start
Installation and User’s Guide shows the exact location and correspondence. With a jumper in
the A position, the corresponding output contact is an “a” type output contact. An “a” type
output contact is open when the output contact coil is deenergized and closed when the output
contact coil is energized. With a jumper in the B position, the corresponding output contact is a
“b” type output contact. A “b” type output contact is closed when the output contact coil is
deenergized and open when the output contact coil is energized. These jumpers are soldered in
place.
In Figure 3 in the Installation section of the SEL-351P Quick-Start Installation and User’s
Guide, note that the ALARM output contact is a “b” type output contacts and the other output
contacts are all “a” type output contacts. This is how these jumpers are configured in a standard
SEL-351P Recloser Control shipment. Refer to corresponding Figure 7.26 for examples of
output contact operation for different output contact types.

The SEL-351P has a dedicated alarm output contact (labeled ALARM – see Figure 3 in the
Installation section of the SEL-351P Quick-Start Installation and User’s Guide). Often more
than one alarm output contact is needed for such applications as local or remote annunciation,
backup schemes, etc. An extra alarm output contact can be had without the addition of any
external hardware.
The output contact next to the dedicated ALARM output contact can be converted to operate as
an “extra alarm” output contact by moving a jumper on the main board (see
Table SECTION 2:
.2).
