QUICK INSTALL GUIDE
3. Mounting
The EL-SC-300 System Controller is designed to mount on a shelf or hang in a cabinet or rack.
Shelf Mounting
The EL-SC-300 has feet to protect finished surfaces. Set the controller in a location that will allow you
to properly manage connected wiring so that tension is not placed on the connections. Wire tension will
cause the unit to move and may cause wires to become disconnected.
Dimensions with feet: 17" W x 2.25" H x 14" D (431.8mm W x 57.2mm H x 355.6mm D)
Rack Mounting
The Rack Mount Brackets included with the EL-SC-300 attach to the chassis using the included screws.
Do not use longer screws to attach the brackets as this may permanently damage the unit.
Remove the feet from the EL-SC-300 before rack mounting the unit. When mounting in very warm
locations (i.e. enclosed rack or cabinet) leave a rack space above and/or below the unit for ventilation.
Dimensions without feet, with rack mount brackets: 19" W x 1.75" H x 14" D (482.6mm W x 44.45mm H x
355.6mm D)
4. RS-232 Serial Connections
Connect up to eight RS-232 serial controlled devices using an included DB9 to RJ45 adapter to the RS-232
port on the rear of the controller.
For null modem connections, the ports can be configured in ELAN Configurator.
