Installation

3 : 1.Location
The intended use of X Series amplifiers is in a rack only. The
AC mains wirings of the units must be connected to a terminal box
provided with a properly breaker (refer to
elettrica for more details). It is not allowed to connect the X Series
AC mains connection directly to the power distribution system.
For North America market we recommend to use an approved
UL/CSA cable (i.e. ST 600Vac 105°C 5x13AWG).
In order to limit the risk of mechanical damages, the ampli-
fiers must be fixed to the rack using both frontal and rear mount-
ing brackets. We recommends to use eight M6 or 12-24 UNC-2B
screws for threaded holes or cage nuts.
Install this amplifier as far as possible from radio tuners and TV
sets. An amplifier installed in close proximity of such equipment
may experience noise or generic performance degradation. 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.
3 : 2.Cooling
Install the amplifier in a well-ventilated location: the ventila-
tion openings must not be impeded by any item such as newspa-
pers, tablecloths, curtains, etc; keep a distance of at least 50 cm
from the front and rear ventilation openings of the amplifier.
All Powersoft amplifiers implement a forced-air cooling
system to maintain low and constant operating temperatures.
Drawn by the internal fans, air enters from the front panel and is
forced over all components, exiting at the back of the amplifier.
The amplifier's cooling system features "intelligent" variable-
speed DC fans which are controlled by the heatsink temperature
sensing circuits: the fans speed will increase only when the
temperature detected by the sensors rises over carefully pre-
determined values. This ensures that fan noise and internal dust
accumulation are kept to a strict minimum.
Should however the amplifier be subject to an extreme ther-
mal load, the fan will force a very large volume of air through the
heat sink. In the extremely rare event that the amplifier should
dangerously overheat, sensing circuits shut down all channels
until the amplifier cools down to a safe operating temperature.
Normal operation is resumed automatically without the need for
user intervention.
X Series amplifiers can be stacked one on top of the other due
to the efficient cooling system they are equipped with.
There is however a safety limit to be observed: in case a rack
with closed back panels is used, leave one rack unit empty every four
installed amplifiers to guarantee adequate air flow (see
10).

air to remove the dust from filters, or wash it with clean water: in
the latter case ensure that the filter is dry before reassembly.

without need of manual selection: true three-phase load balanc-

assignment in the power distribution system design.
