Schweitzer Engineering Laboratories SEL-2245-4 User Manual

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.

Mechanical Installation
Each SEL-2242 chassis/backplane has four or ten slots,
labeled A–J. Slots B–J support 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.
