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.
