Rack Mounting Ventilation Recommendations

Excessive heat can decrease the optimal lifetime of the power amplifier. An over temp indicator LED on the front panel of the amplifier lights red whenever the recommended operating temperature has been exceeded. See “Front Panel Features and Operation” on page 9.

To reduce the chances for an over temp condition, the XPAs should be arranged in a rack environment so that adequate airflow is available both above and below the XPA whenever possible. No more than two XPAs should be arranged one-on-top-of-the-other in a rack without an open space between them, as shown in the following illustration. An XPA can also be arranged above or below another non-XPA device, but there must be an open space both above and below those devices.

The circuit breaker used for this connection should be rated no lower than 20 amps and no greater than 30 amps.

This unit must be installed in accordance with the National Electrical

Code and with all local codes.

An ALL-POLE MAINS SWITCH with a contact separation of at least

3 mm in each pole shall be incorporated in the electrical installation of the building. The installation shall be carried out in accordance with all applicable installation rules.

Installation and service must be performed by a qualified electrician only.

ATTENTION: Failure to follow these instructions may result in damage to the unit.

A UL listed electrical distribution box is recommended for the termination of the conduit opposite the XPA. See the following “UL Requirements” section on page 7.

The optional Flexible Conduit Adapter Kit (Extron part #70-228-02) consists of

One EMT adapter plate

One 6-foot long electrical conduit
