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.
