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

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.
