6 : 3.AC mains supply
The AC Main connection is made via the
f
f
AMP CPC 45A connector in K6, K8, K10 and K20;
f
f
IEC C20 connector in K3 and K2.
The
FIGURE 7
shows how to connect the mains power
cable to the amplifier.
Make sure the AC mains voltage used
is within the acceptable operating
voltage range: 115V-230V ±10%.
It is important to connect the ground
for safety, do not use adapters that
disable the ground connection.
All K Series amplifiers have an automatic power factor
correction system – PFC – for a perfect mains network
interface. The PFC minimizes the reactive power reflected
on the network and reduces the harmonic distortion on the
voltage/current waveform: in this way the amplifier is seen
as a resistive load from the mains network. Furthermore, the
system allows performance to be maintained even in case
of varying mains voltage.
6 : 4.Precautions regarding installation
Placing and using the amplifier for long periods of time
on heat generating sources will affect its performance. Avoid
placing the amplifier on heat generating sources. Install this
amplifier as far as possible from tuners and TV sets. An
amplifier installed in close proximity of such equipment may
experience noise or generic performance degradation.
The power cord type provided with the amplifier are

WARNING: TO PREVENT FIRE OR ELECTRIC SHOCK
f
f
This device must be powered exclusively by earth con-
nected mains sockets in electrical networks compliant
to the IEC 364 or similar rules.
f
f
Install K6, K8, K10 and K20 into rack cabinet.
f
f
With K6, K8, K10 and K20 a sectioning breaker be-
tween the mains connections and the amplifier must
be installed inside the rack cabinet. Suggested device
is 32A/250VAC, C or D curve, 10kA.
f
f
With K2 and K3 provide a sectioning breaker between
the mains connections and the amplifier. Suggested
device is 16A/250VAC, C or D curve, 10kA.
f
f
Before powering this amplifier, verify that the correct
voltage rating is being used.
f
f
Verify that your mains connection is capable of satisfy-
ing the power ratings of the device.
f
f
Do not use this amplifier if the electrical power cord is
frayed or broken.
f
f
Output terminals are hazardous: wiring connection to
these terminals require installation by an instructed
person and the use of ready made leads.
f
f
Take care to secure the output terminal before switch-
ing the device on.
f
f
To avoid electrical shock, do not touch any exposed
speaker wiring while the amplifier is operating.
f
f
Do not spill water or other liquids into or on the amplifier.
f
f
No naked flame sources such as lighted candles
should be placed on the amplifier.
f
f
Do not remove the cover. Failing to do so will expose
you to potentially dangerous voltage.
f
f
It is absolutely necessary to verify this fundamental
requirement of safety and, in case of doubt, require an
accurate check by qualified personnel.
f
f
The manufacturer cannot be held responsible for
damages caused to persons, things or data due to an
improper or missing ground connection.
f
f
Contact the authorized service center for ordinary and
extraordinary maintenance.
