10 | X Series | User guide
AC mains connection is provided by means of the eu-
roblock Phoenix PC 5/5-STF1-7,62 connector and ying
plug (Phoenix product ID 1777862). Proper assembly of the
AC mains conductors to the ying plug must respect the
power line conguration.
Take care to connect all the ve conductors to the ying
plug in order to guarantee the proper wire section: recom-
mended wires section is 2,5mm
2
/ 13 AWG (ref. TABLE 1).

For X4 Powersoft suggests:
monophase AC (P+N+E): 16 A rating, C or D curve, 10 kA;
triphase AC (3P+N+E): 4 x 10 A rating, C or D curve, 10 kA.
Before connecting this amplier to the AC mains:
f verify that your mains connection is capable to satisfy
the power ratings of the device;
f verify that a ground connection is available;
f verify that a proper sectioning breaker is available;
f do not use this ampliler if the electrical power cord is
frayed or broken;
f connect all the ve conductors to the ying plug as
shown in the pictures.
11 : 4.1. Three-phase electric power
Usually, three-phase AC mains encompass four power
conductors plus ground (i.e. totally ve conductors) in a
so called 3P+N+E three phase with neutral conguration.
In some instances neutral connection may lack: on three-
phase systems neutral connection is not even neces-
sary given the capability of the X Series to work in delta
connection.
Each single conductor must be secured to the
PC 5/5-STF1-7,62 ying plug as shown in FIGURE 10.
The following operations can be performed
only by professional or qualified personnel
according to local electrical authorities guidelines.
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-
vides a complete insulation of the equipment from the main
power, you must disconnect the main power source to turn
off all power.
Provide a sectioning breaker between the
mains connections and the amplifier.
The proper device to use depends on mains congura-
tion; for X8 Powersoft suggests:
monophase AC (P+N+E): 32 A rating, C or D curve, 10 kA;
triphase AC (3P+N+E): 4 x 16 A rating, C or D curve, 10 kA.
11 : 4.AC mains supply
X Series ampliers offers worldwide AC acceptance and
direct connection to any regional power line conguration.
Powersoft’s legendarily reliable power supply is now suitable
to single-phase, bi-phase or three-phase operation from 85
V
AC
up to 440 V
AC
(nominally 100 V
AC
to 240 V
AC
±10% mono-
phase and 173 V
AC

need of manual selection: true three-phase load balancing
is directly achievable by the unit without any complex load
assignment in the power distribution system design.
