installation OVERVIEW

Ventilation Requirements

Important: The MCA-C5 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 MCA-C5 above or below a heat-generating component such as an audio amplifier.

Be sure to leave at least 2 inches of space to the sides of the unit with open air flow above. A single-space rack mount vent or about 1.75 inches must be kept clear above and below the unit.

Installation

The MCA-C5 controller can be rack mounted or placed on a shelf in an equipment rack. The controller will occupy two rack spaces 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.

Up to six controllers may be connected and allow up to 48 zones on the system.

Electrical Power

The MCA-C5 operates at 100-120VAC ~60 Hz or 220-240VAC ~50 Hz. Voltage is selected by the voltage switch on the rear panel and incorporates the appropriate detachable power cord. It is recommended that the MCA-C5 and the source equipment be plugged into a dedicated 20-amp circuit. A power line conditioner can reduce interference problems caused by noise found in some electrical systems.

The power switch for the unit is on the front panel.

Do not connect the controller’s main power feed until all other connections have been made and verified. 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.

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 multiple controllers, the controller ID must be set with the rotary switch on the rear panel. Each controller must be set to a unique number before powering connected controllers.

Important: The necessary software (SCS-C5) to program and configure the system is available via download from the doc center at www.russound.com. With your laptop, you can configure the system and name all of the zones prior to connecting with the MCA-C5 controller. See Section on page 27 for items to be programmed with the software.
