Rack Mount
We offer the SEL-387E Relay in a rack-mount version that bolts easily into a standard 19-inch
rack. See
Figure 2.1. From the front of the relay, insert four rack screws (two on each side)
through the holes on the relay mounting flanges.
Reverse the relay mounting flanges to cause the relay to project 2.75 inches (69.9 mm) from the
front of your mounting rack and provide additional space at the rear of the relay for applications
where the relay might otherwise be too deep to fit.
Panel Mount
We also offer the SEL-387E Relay in a panel-mount version for a clean look. Panel-mount
relays have sculpted front-panel molding that covers all installation holes. See
Figure 2.1. Cut
your panel and drill mounting holes according to the dimensions in
Figure 2.1. Insert the relay
into the cutout, aligning four relay mounting studs on the rear of the relay front panel with the
drilled holes in your panel, and use nuts to secure the relay to your panel.
The projection panel-mount option covers all installation holes and maintains the sculpted look
of the panel-mount option; the relay projects 2.75 inches (69.9 mm) from the front of your panel.
This ordering option increases space at the rear of the relay for applications where the relay
would ordinarily be too deep to fit your cabinet.
