QSC Audio CM16a - Manual (Page 18)

Section 2:
Installation- Mounting and AC Power
MOUNTING THE CM16a (continued): The illustration below shows the basic mounting technique.
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 that 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. Keep in mind that some
equipment rack installation environments can get quite 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.
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 85 to 264 Volts AC, 47 to 440 Hertz, without any changes. Make
sure that the power cord used is suitable for the line voltage that 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.
