About This
Quick-Start Installation and User’s Guide
This SEL-351R Recloser Control Quick-Start Installation and User's Guide
helps you install, communicate with, set, and test the SEL-351R in its EZ
(“easy”) mode of operation. The EZ mode performs traditional recloser
control functions and operations.
SEL designed the SEL-351R based on the SEL-351 Distribution Relay. The
SEL-351R has full SEL-351 Relay functionality together with a modified user
interface designed for recloser control. When using the SEL-351R as a
traditional line recloser control, it is only necessary to access the EZ Level
(Access Level E) Settings. See the SEL-351R Recloser Control Instruction
Manual for complete information regarding the full functionality of the
SEL-351R.

Some Cooper reclosers have an internal battery charging transformer (current
transformer). This charging transformer is not used by the SEL-351R. Its
24 Vdc battery is charged from a user-supplied 120 Vac power source. If one
of these reclosers is connected to the SEL-351R, this charging transformer is
electrically shorted at the control cable receptacle (see Figure 1.13; pins K and
L are shorted together and grounded).
Terminal Block ➤Rail: DIN 3
➤Screws: #6-32
➤Lug width: 0.334" max. (8.5 mm)
Accessories Accessories can be mounted on the back panel, above the terminal block. See
Figure 1.10 for more details.
Control Cable The SEL-351R uses the same control cable that connects a Kyle Form 3, 3A,
4, 4A, 4C, or Type FXA or FXB control to a Cooper three-phase recloser.

Ground Connection to Required System Grounding
Important Notes for
Installation Step 2
1. All devices interfacing to the SEL-351R must be connected to
the same pole ground. Figure 1.4 shows a suggested method of
making these connections.
2. All connections to the SEL-351R must be routed in close
proximity to and parallel to their corresponding ground paths
for adequate surge protection. The connections and their
ground paths should be approximately equal in length. Use
applicable IEEE and IEC grounding standards. Follow the
preceding recommendations to reduce high potentials from
surges that can damage equipment.
3. External control wiring brought into the SEL-351R enclosure
for connection to the extra I/O (output contacts OUT101 through
ALARM and optoisolated inputs IN101 through IN106; see
Figure 1.9 and Figure 1.12) should be protected within
shielded cables. The cable shields must be grounded at the
grounding lug bolt inside the SEL-351R enclosure (see
Figure 1.13).

CAUTION
Separable connector J12 should be the
first disconnected when removing
batteries and the last connected when
installing batteries. Do not leave J12
connected without the batteries also
connected. The tab disconnects on the
battery wiring harness are energized
and can short-circuit if they come in
contact with the enclosure floor or
each other, consequently damaging
the internal power supply.

Installation
Installation Step 4: Wake Up the Control
Set the batteries inside the battery fence as shown in Figure 1.2. Fasten and
secure the hook and loop strap over the battery top. Connect the battery wiring
harness as shown in Figure 1.6, following the instructions given in the
accompanying CAUTION. Note that the small jumper wire in the harness
connects the (–) terminal of one 12 Vdc battery to the (+) terminal of the other
12 Vdc battery to make an effective 24 Vdc battery.
Installation Step 4: Wake Up the Control
Press the front-panel {WAKE UP} operator control, and the SEL-351R turns on.
The following should be observed:
➤CONTROL ENABLED LED illuminates
➤BATTERY PROBLEM LED remains extinguished

WAKE UP
WITHOUT {WAKE UP}:
If Installation Step 4 is skipped, the
SEL-351R will turn on automatically
when Installation Step 6 is executed.
Application of 120 Vac power always
turns on the SEL-351R.
NO If not connecting three-phase voltage, go directly to
Installation Step 6: Connect the 120 Vac Power on
page 1.7.
YES If connecting three-phase voltage, read and understand
the following subsections and then answer the following
question:
Option 1: Connect Three-Phase and Synchronism
