4.1. Three-Phase Electric Power; 4.2. Two-Phase Electric Power; 4.3. Single-Phase Electric Power; 5.Precautions Regarding Installation - Powersoft audio X Serie Guía Rápida

Provide a sectioning breaker between the
mains connections and the amplifier.
The proper device to use depends on mains configura-
tion; for X8 powersoft suggests:
single-phase ac (p+N+E): 32 a rating, c or D curve, 10 ka;
three-phase ac (3p+N+E): 4 x 16 a rating, c or D curve, 10 ka.
For X4 powersoft suggests:
single-phase ac (p+N+E): 16 a rating, c or D curve, 10 ka;
three-phase ac (3p+N+E): 4 x 10 a rating, c or D curve, 10 ka.

TAB. 1: Color code for conductor identification.
AC mains connections must be performed
only by professional or qualified personnel
according to local electrical authoritie guidelines.

3 : 4.1. Three-phase electric power

Each single conductor must be secured to the
pc 5/5-STF1-7,62 flying plug as shown in
some instances neutral connection may lack: on three-phase
systems neutral connection is not even necessary given the
capability of the X Series to work in delta connection.

3 : 4.2. Two-phase electric power

Balanced two-phase ac mains in the configura-
tions 2p+E without neutral must be secured to the
pc 5/5-STF1-7,62 flying plug as shown in
Take care to double the phase wires at the connecting ter-
minals of the sectioning breaker in order to guarantee the
proper conduction gauge.

3 : 4.3. Single-phase electric power

p+N+E, unbalanced single-phase with neutral is the
usual configuration for signle-phase ac mains; wiring must
be configured as shown in
double the phase and neutral wires at the connecting ter-
minals of the sectioning breaker in order to guarantee the
proper conduction gauge.

3 : 5.Precautions regarding installation

WARNING: TO PREVENT FIRE OR ELECTRIC SHOCK
f This device must be powered exclusively by earth con- f
nected mains sockets in electrical networks compliant
to the iEc 364 or similar rules.
f install the unit into rack cabinet only. f
f a sectioning breaker between the mains connections f
and the amplifier must be installed inside the rack
cabinet.
f Take care to properly lock each power cord wire to the f
flying connector phoenix pc 5/5-STF1-7,62.
f once properly wired, insert and lock the flying connec-
f
tor into the shell provided by powersoft.
f Lock the flying connector to the amplifier inlet.
f
f Before powering this amplifier, verify that the correct f
voltage rating is being used.
f Verify that your mains connection is capable of satisfy- f
ing the power ratings of the device.
f Do not use this amplifier if the electrical power cord is f
frayed or broken.
f output terminals are hazardous: wiring connection to f
these terminals require installation by an instructed
person and the use of ready-made leads.
f Take care to lock the output terminal before switching f
the device on.
f To avoid electrical shock, do not touch any exposed
f
speaker wiring while the amplifier is operating.
f Do not spill water or other liquids into or on the amplifier.
f
f No naked flame sources such as lighted candles f
should be placed on the amplifier.
f Do not remove the cover. Failing to do so will expose f
you to potentially dangerous voltage.
f The manufacturer cannot be held responsible for f
damages caused to persons, things or data due to an
improper or missing ground connection.
f contact the authorized service center for ordinary and f
extraordinary maintenance.
It is absolutely necessary to verify these fundamental
requirement of safety and, in case of doubt, require
an accurate check by qualified personnel.
