Schweitzer Engineering Laboratories, Inc. SEL-2243 Data Sheet
Every SEL Axion®node requires at least one SEL-2243 Power Coupler module. The SEL-2243 serves two purposes in
an Axion system:
1. It is the power supply for all modules installed in the node, and;
2. It provides two dedicated EtherCAT®ports so that multiple Axion nodes can operate together.

Power Supply Operation
One SEL-2243 has sufficient power capacity to accom-
modate an entire Axion node. The terminal strip at the
bottom of the unit, as seen in Figure 1, is the connection
point for incoming power. All Axion modules have a
55-position IEC C-style connector that provides a com-
munications and power interface to the backplane. The
SEL-2243 provides power to the node via the backplane
connector.
The power coupler module uses the same power supply
design that you would find in SEL protective relays. The
Axion provides test-proven superior performance and
availability, while also allowing for redundant power
couplers in a node for applications that need these. If you
install two power couplers in a node, both modules
actively share load and provide the necessary power for
node functions. If one SEL-2243 becomes unavailable,
there is zero switching delay or power loss to the node.
EtherCAT Operation
Each SEL-2243 provides two dedicated ports for Ether-
CAT networks. The ports will either be standard
10/100BASE-T or optional 100BASE-FX Ethernet ports.
EtherCAT is a real-time fieldbus protocol (see
Appendix E in the ACSELERATOR RTAC SEL-5033
Instruction Manual) that we can use to connect an RTAC
to I/O modules in an Axion system. If the installation has
only one node, then the backplane transmits EtherCAT
messages. Alternatively, if you use an SEL-3530 RTAC,
or if you need more I/O than will fit in a node, then the
ports on a power coupler module provide a mechanism
for extending the EtherCAT network through the use of
dedicated Ethernet wiring. Refer to EtherCAT in
Section 2: Communications in the ACSELERATOR RTAC
SEL-5033 Instruction Manual to learn more about con-
figuring a network.
If an Axion node contains two SEL-2243 modules, then
the EtherCAT ports in both power couplers will operate
normally even if one power supply becomes unavailable.
The remaining power supply will serve as the source for
all I/O modules and communications needs.

Mechanical Installation
Each SEL-2242 chassis/backplane has ten slots, labeled
Athrough J. Only slots A, B, and Csupport the SEL-2243
Power Coupler module.
To install the power coupler, tip the top of the module
away from the chassis, align the notch on the bottom of
the module with the slot you have selected in the chassis,
and place the module on the bottom lip of the chassis
(Figure 2). The module is aligned properly when it rests
entirely on the lip of the chassis.
Figure 2 Proper Module Placement
Next, carefully rotate the module into the chassis, mak-
ing sure that the alignment pin fits into the corresponding
slot at the top of the chassis (refer to Figure 3). Finally,
press the module firmly into the chassis and tighten the
chassis retaining screw.

Connections
General
Terminals are not intended for use with bare conductors.
Solid or stranded wire can be used with ferrule or spade
terminals. The customer is responsible for verifying that
wire insulation and temperature ratings are sufficient for
their application.
Power
DANGER
Contact with this circuitry may cause electrical shock that can result in
injury or death.
CAUTION
Capacitors should be safely discharged during decommissioning.
The power terminals on the high-voltage power coupler
(1 (+/H) and 2 (–/N)) must connect to 120/240 Vac with
the proper polarity or to 125/250 Vdc. The power
terminals on the low-voltage power coupler (1 (+/H) and 2
(–/N)) must connect to 24/48 Vdc. The power terminals
are isolated from the chassis ground. Use 14 AWG
(2.1 mm2) with an external 15 A branch circuit
protection device or 12 AWG (3.3 mm2) wire with an
external 20 A branch circuit protection device.
Grounding (Earthing)
Connect the ground terminal labeled GND (3) on the
power coupler to a rack frame or switchgear ground for
proper safety and performance. Use 14 AWG (2.5 mm2)
wire of sufficient current capacity and insulation voltage
ratings that is less than 2 m (6.6 ft) in length for the
ground connection.
EtherCAT Ports
CAUTION
Always ensure that power couplers are not connected to any Ethernet
switches or other Ethernet devices, including RJ45-to-fiber-optic
converters. The power coupler EtherCAT ports are only for direct
connections between power couplers of the same type or to an RTAC
EtherCAT port. Connecting a power coupler to any other Ethernet device
can cause the EtherCAT network to stop communicating completely or
have unpredictable behavior.
The SEL-2243 includes two 10/100BASE-T or
100BASE-FX Ethernet ports dedicated for EtherCAT
protocol. Use a standard RJ45 connector for a copper
port and an LC connector for a fiber-optic port to connect
PORT 1 or PORT 2 of the module. Make each connection by
using a direct cable to the next device. Use SEL cable
SEL-C627 with copper ports. Copper cables for EtherCAT
connections should be less than 3 m (10 ft) in length.
Buttons and LEDs
Each power coupler includes a LAMP TEST button useful
for system testing. When depressed, all module LEDs on
the terminal side and front panel (rack mount only) will
illuminate.
The green LED labeled POWER on the SEL-2243 will illu-
minate if incoming power is present and the power sup-
ply is operating normally. The LEDs labeled ENABLED
and ALARM are related to EtherCAT network operation.
The green ENABLED LED will illuminate when the mod-
ule is operating normally on the network. The ALARM
LED will illuminate during network initialization or
when there is a problem with the network.
