Installation- Mounting and AC Power

CONNECTING AC POWER

The CM16a uses a detachable IEC standard power cord for connecting to a grounded AC

source. To connect power to the CM16a: identify the proper end of the cord,  match the

orientation of the receptacle on the rear panel and insert firmly into the receptacle.  The

power supply will accept from 100 to 240 Volts AC, 47 to 440 Hertz, without any changes.

The power cord used must be suitable for the line voltage the CM16a is connected to. If a

different type of IEC power cord is required (different style of plug on the outlet end) contact

QSC’s Technical Services Department to obtain the correct cord assembly.

DO NOT CONNECT THE CM16a TO POWER SOURCES OUTSIDE THE SPECIFIED

RANGES OF VOLTAGE OR FREQUENCY! DAMAGE TO THE UNIT COULD RESULT OR

THE USER COULD BE EXPOSED TO UNSAFE OPERATING CONDITIONS.

MOUNTING THE CM16a (continued):

 The illustration below, left,  shows the basic mounting technique. Support the CM16a from

underneath while positioning the mounting holes in the desired location in the rack. Secure with standard rack hardware. The CM16a uses

fan-drawn air for cooling. The air intake is on the left side of the chassis and the exhaust vents are on the front panel. Be certain not to obstruct

these openings! Allow ample “open space” around them in order to maintain unobstructed air flow.

Note! 

 The CM16a’s recommended ambient operating temperature is  0°C. to  50°C. (32°F. to 122°F.).

 Do not

install the CM16a in environments that expose it to temperatures outside this range.

 Some equipment

rack  environments can get  hot. If there is any question, measure the air temperature inside the equipment rack

and supply additional cooling (air flow)  to keep the ambient temperature within the specified limits. QSC amplifiers

use back-to-front air flow and therefore do not exhaust hot air into the rack.
