4.3. AC Mains supply
The AC Main connection is made via the IEC C13
connector.
Connection to the main shall be
done only by an electrotechni-
caly skilled person according to
the national requirements of the
countries where the unit is sold.
Make sure the AC mains volt-
age used is within the accept-
able operating voltage range:
115V-230V ±10%.
It is important to connect the
ground for safety, do not use
an adapter that disables the
ground connection.
The TDC 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 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.
4.4. Precautions regarding installation
Placing and using the amplifier for long periods 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 close to
such equipment may experience noise or generic
performance degradation.
WARNING: TO PREVENT FIRE OR ELECTRIC
SHOCK:
- This device must be powered exclusively by earth-
connected mains sockets in electrical networks
compliant with the IEC 364 or similar rules.
- Install the amplifier into a rack cabinet.
- With a TDC amplifier, a sectioning breaker between
the mains connections and the amplifier must be
installed inside the rack cabinet. The suggested
device for TDC-1200W and TDC-3200W is 10A class
C or D.
- 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 connections
to these terminals require installation by an instructed
person.
- Take care to secure the output terminal before
switching the device on.
- 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 necessary to verify these fundamental
requirements 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 center for ordinary
and extraordinary maintenance.
