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
alimentazione 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
amplifiers must be fixed to the rack using both frontal and
rear mounting 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 ven-
tilation openings must not be impeded by any item such as
newspapers, 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 tempera-
tures. 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" var-
iable-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 predetermined 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
thermal 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 panel G, p. 10).

3 : 3.Cleaning

always use a dry cloth for cleaning the chassis and the
front panel. air filter cleaning should be scheduled according
§3 : 4. to the dust levels in the amplifier's operating environment.
Disconnect the AC mains source before
attempting to clean any part of the amplifier
in order to clean the vent filters you need to remove the
front cover: never attempt to open any other part of the unit.
By means of a metric hex key #6, unscrew the two
screws located on the left and right sides of the front panel,
(see FiG. 1) gently lift the cover and remove the filter. You
may use compressed 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.
FIG. 1: Use a #6 hex key to remove the front cover.

3 : 4.AC mains supply

X Series amplifiers offers worldwide ac acceptance and
direct connection to any regional power line configuration.
powersoft's legendarily reliable power supply is now suit-
able to single-phase, two-phase or three-phase operation
from 90 V up to 464 V
ac
true three-phase load balancing is directly achievable by
the unit without any complex load assignment in the power
distribution system design.
ac mains connection is provided by means of the eu-
roblock phoenix pc 5/5-STF1-7,62 flying plug (phoenix
product iD 1777862). proper assembly of the ac mains
conductors to the flying plug must respect the power line
configuration.
Take care to connect any and all the five contacts of the
flying plug to the power cords according to the configuration
showed in panel k, L, M
guarantee the proper connection we recommend to use an
approved uL/cSa cable (i.e. ST 600Vac 105°c 5x13aWG).
This device must be powered exclusively by
earth connected mains sockets in electrical
networks compliant to the IEC 364 or similar rules.
Since the main power switch on this unit does not pro-
vide a complete insulation of the equipment from the main
power, you must disconnect the main power source to turn
off all power.
