SEL-2245-42 AC Protection Module The SEL-2245-42 provides ac analog inputs for the SEL Axion®. Install as many as nine SEL-2245-42 modules within an Axion node and as many as sixteen SEL-2245-42 modules per system in any combination you want. Front Panel Mechanical Installation Each SEL-2242 chassis/backplane has four or ten slots, labeled A–J. Slots B–J support the SEL-2245-42 modules. Schweitzer Engineering Laboratories, Inc. Notch for Module Alignment To install an SEL-2245-42 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.

Input Connections The SEL-2245-42 CT/PT analog inputs include a dot next to the terminal number to indicate the positive connection. Refer to Specifications for ac analog input ratings and to Figure 5 for terminal assignments. You can configure potential transformer (PT) inputs for 6-300 V and current transformer (CT) inputs for 0-20 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...
