Convection cooled — The XTRA Series of amplifiers are convection cooled without the need for fans, ensuring quiet, reliable operation. Ultra low inrush current - no need for power sequencing — Allows many XTRA Series amplifiers to be powered on simultaneously without overloading power circuits. This eliminates the need for power sequencing. Flexible Conduit Adapter Kit, part # 70-228-02 — Suitable for use in other environmental air space in accordance with section 300.22, (C) of the Nation

3. Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading. 4. Circuit overloading — Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern. 5. Reliable earthing (gr

NOTE: If needed, Extron recommends using a UL-rated crimp tool to terminate the spade connectors. One recommended choice is the Molex crimp tool (Molex part #64001-0100). The kit provides a convenient means to replace the XPA’s IEC power cord with conduit, where required by local codes. WARNING: Failure to follow these instructions may result in serious injury. Make sure that the source device and the XPA are turned off and disconnected from the power source before you begin. UL Requirement
