10 Russound CA4 System Installation Manual
INSTALLATION OVERVIEW
Ventilation Requirements
IMPORTANT: The CA4 should be situated so that its location or position does
not interfere with its proper ventilation. Do not block vents above or to the
sides of the unit, as it requires ventilation for proper operation. Do not expose
to excessive dust, and do not allow dust to build up on the unit and block vent
holes. Do not place the CA4 above or below a heat-generating component
such as an audio amplier.
Be sure to leave at least 2 inches of space to the sides of the unit with open air
ow above. A single-space rack mount vent or about 1.75 inches must be kept
clear above and below the unit.
Installation
The CA4 controller can be rack mounted or placed on a shelf in an equipment
rack. The controller will occupy one rack space with the feet removed.
The controller can be installed in an equipment rack using the included rack-
mount ears and hardware to attach the ears to the controller chassis.
Two controllers may be connected and allow up to 8 keypads on the system.
Electrical Power
The CA4 operates at 100 to 240 VAC. Voltage is auto selected internally. It
is recommended that the CA4 and the source equipment be plugged into a
dedicated 20-amp circuit with an isolated ground. A power line conditioner
can reduce interference problems caused by noise found in some electrical
systems.
Warning: There is no external on/o power switch on the CA4. If the controller
is plugged in to a live AC outlet, it will be powered. To cycle power, you must
unplug the controller and then plug it back in.
Important Considerations
Disconnect the power cord before making any connections to the •
controller.
Verify that all connections and polarity are correct.•
Keep all power cords away from all signal cables to prevent humming from •
induced noise.
Choose reliable signal cables and patch cords.•
Label all wires with the room location at both ends of the wire.•
Avoid running speaker wires or signal cables close to house electrical •
wiring for any distance. If you have to run them parallel, make sure to space
the wires at least two feet from the AC line. If you need to cross an AC line it
should be at a 90° angle.
For dual controllers, use a keypad connected through a wall port to set the •
ID on the second controller before linking the controllers.
Do not connect the controller’s main power feed until all other
connections have been made and veried. Live connection or
removal of the keypad wiring or other wiring when the system
is powered can cause communication problems in the network.
Double-check terminations during each phase of the installation
to prevent accidental damage. Incorrect wiring is the number one
cause for non-warranty product damage.
