Provide a sectioning breaker between the
mains connections and the amplifier.
The proper device to use depends on mains configuration;
for Bias Q5 Void 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.
NOTE: The pictures and instructions about AC wiring refer
to the European CENELEC standards April 2004 (IEC 60446)
color code for conductor identification (see table 1).

AC mains connections must be
performed only by professional
or qualified personnel according
to local electrical authoritie guidelines.
4.4.1 Three-phase electric power
Each single conductor must be secured to the
PC 5/5-STF1-7,62 flying plug as shown in
Panel I, p. 8
. In
some instances neutral connection may lack: on three-phase
systems neutral connection is not even necessary given
the capability of the Bias Q5 to work in delta connection.
4.4.2 Two-phase electric power
Balanced two-phase AC mains in the configurations 2P+E
without neutral must be secured to the PC 5/5-STF1-7,62
flying plug as shown in
Panel K, p. 9
. Take care to double the
phase wires at the connecting terminals of the sectioning
breaker in order to guarantee the proper conduction gauge.
4.4.3 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
Panel J, p. 8
. Take
care to double the phase and neutral wires at the
connecting terminals of the sectioning breaker in
order to guarantee the proper conduction gauge.
4.5 Precautions regarding installation
WARNING: TO PREVENT FIRE OR ELECTRIC SHOCK
•
This device must be powered exclusively by earth
connected mains sockets in electrical networks
compliant to the IEC 364 or similar rules.
•
Install the unit into rack cabinet only.
•
A sectioning breaker between the mains
connections and the amplifier must be
installed inside the rack cabinet.
•
Take care to properly lock each power cord wire to
the flying connector Phoenix PC 5/5-STF1-7,62.
•
Once properly wired, insert and lock the flying
connector into the shell provided by Void.
•
Lock the flying connector to the amplifier inlet.
•
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 connection
to these terminals require installation by an instructed
person and the use of ready-made leads.
•
Take care to lock 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.
•
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.
It is absolutely necessary to verify these fundamental
requirement of safety and, in case of doubt, require
an accurate check by qualified personnel.
4.6 Switch on
As soon as you connect the amplifier to the power grid, the
amplifier’s power supply will start supplying power to the
auxiliary systems. The border of the central button starts
blinking white: the amplifier is in standby mode.
A pressure on the central button will wake up the amplifier.
