Schweitzer Engineering Laboratories SEL-2245-4 Manual de usuario
Schweitzer Engineering Laboratories, Inc. SEL-2245-4 Data Sheet
The SEL-2245-4 provides ac metering inputs for the SEL Axion®. Within an Axion node, install as many as sixteen
SEL-2245-4 modules per system in any combination you want.

Figure 1 SEL-2245-4 AC Metering Module
Mechanical Installation
Each SEL-2242 chassis/backplane has four or ten slots,
labeled A–J. Slots B–Jsupport the SEL-2245-4 modules.
Figure 2 Notch for Module Alignment
To install an SEL-2245-4 module, tip the top of the
module away from the chassis, align the notch on the
bottom of the module (shown in Figure 2) with the slot
you want on the chassis, and place the module on the
bottom lip of the chassis as Figure 3 illustrates. The
module is aligned properly when it rests entirely on the
lip of the chassis.

Figure 3 Proper Module Placement
Next, carefully rotate the module into the chassis,
making sure that the alignment tab fits into the
corresponding slot at the top of the chassis (refer to
Figure 4). Finally, press the module firmly into the
chassis and tighten the chassis retaining screw.
Figure 4 Final Module Alignment
Input Connections
The SEL-2245-4 CT/PT analog inputs include a dot next
to the terminal number to indicate the positive
convention. Refer to Specifications for ac analog input
ratings and to Figure 5 for terminal assignments. You can
configure potential transformer (PT) inputs for 5–400 V
and current transformer (CT) inputs for 0–22 A.
Configure inputs by adding a Fieldbus I/O connection for
each module in ACSELERATOR RTAC®SEL-5033
Software. See the EtherCAT®portion in Section 2:
Communications in the SEL-5033 Software Instruction
Manual for details.
Figure 5 CT/PT Analog Inputs
LED Indicators
The LEDs labeled ENABLED and ALARM are related to
EtherCAT network operation. The green ENABLED LED
illuminates when the module is operating normally on
the network. The ALARM LED illuminates during network
initialization or when there is a problem with the
network.
CAUTION
Use supply wires suitable for 60°C (140°F) above ambient. See product
or manual for ratings.
ATTENTION
Utilisez des fils d'alimentation appropriés pour 60°C (140°F) au-dessus
ambiante. Voir le produit ou le manuel pour les valeurs nominales.
