6.3 AC mains supply
The AC Main connection is made via the
• AMP CPC 45A connector in Bias V9;
• IEC C20 connector in Bias V3
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 Bias 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
•
LAPP OLFLEX191 3G6 / SJT 3XAWG10
for Bias V9.
•
Bahoing SJT 3x16AWG or I-sheng SGIS 3G 1,5 mm

for Bias V3.
WARNING: TO PREVENT FIRE OR ELECTRIC SHOCK
•
This device must be powered exclusively by earth
connected mains sockets in electrical networks
compliant to the IEC 364 or similar rules.
•
Install Bias V9 into rack cabinet.
•
With Bias V9 a sectioning breaker between the
mains connections and the amplifier must be
installed inside the rack cabinet. Suggested
device is 32A/250VAC, C or D curve, 10kA.
•
With Bias V3 provide a sectioning breaker between
the mains connections and the amplifier. Suggested
device is 16A/250VAC, C or D curve, 10kA.
•
Before powering this amplifier, verify that the
correct voltage rating is being used.
•
Verify that your mains connection is capable of
satisfying the power ratings of the device.
•
Do not use this amplifier if the electrical
power cord is frayed or broken.
•
Output terminals are hazardous: wiring connection
to these terminals require installation by an instructed
person and the use of ready made leads.
•
Take care to secure the output terminal
before switching the device on.
•
To avoid electrical shock, do not touch any exposed
speaker wiring while the amplifier is operating.
•
Do not spill water or other liquids into or on the amplifier.
•
No naked flame sources such as lighted
candles should be placed on the amplifier.
•
Do not remove the cover. Failing to do so will
expose you to potentially dangerous voltage.
•
It is absolutely necessary to verify this fundamental
requirement of safety and, in case of doubt, require
an accurate check by qualified personnel.
•
The manufacturer cannot be held responsible for
damages caused to persons, things or data due
to an improper or missing ground connection.
•
Contact the authorized service centre for
ordinary and extraordinary maintenance.
Connection to the mains shall be done
only by a electrotechnical Skilled person
