3. The device must be free of any voltage before performing any alterations with upgrade sets,
switching the mains voltage, or performing any other modifications.
4. The minimum distance between voltage-carrying parts and metal parts that can be touched (such
as the metal housing) or between mains poles is 3 mm, and must be observed at all times.
5. The minimum distance between voltage-carrying parts and circuit parts that are not connected to
the mains (secondary) is 6 mm, and must be observed at all times.
6. Special components that are marked with the safety symbol in the circuit diagram (note) must only
be replaced with original parts.
7. Unauthorized changes to the circuitry are prohibited.
8. The protective measures issued by the relevant trade organizations and applicable at the place of
repair must be observed. This includes the properties and configuration of the workplace.
9. Observe the guidelines with respect to handling MOS components.

1.3. Safety precautions
Speaker system damage and protection of human beings
Power amps provide extremely high power output that might be dangerous for human beings as well
as for the connected speaker systems. High output voltages can damage or even destroy the
connected speaker systems, especially, when the amplifier is operated in bridged mode. Prior to
connecting any loudspeakers, make sure to check the speaker system’s specifications for continuous
and peak power handling capacities. Even if amplification has been reduced through lowering the
input level controls on the amplifier’s front panel, it is still possible to achieve full power output with a
sufficiently high input signal.
Danger!
Danger at the loudspeaker/power outputs
Power amplifiers are capable of producing dangerously high voltage output that is present at the
output connectors. To protect yourself from electric shock, do not touch any blank speaker cables
during operation of the power amp.
Danger!
The terminals marked with a lightning bolt are hazardous live and the external wiring connected to
these terminals requires installation by an instructed person or the use of readymade leads of cords.
Danger!
In case of using the amplifier with speakers including a primary tapped transformer, it is possible that
during operation shock hazard voltages may be present at the taps of the transformer. Therefore, the
taps have to be insulated sufficiently in accordance with applicable safety regulations.

2.1 Short Information
Items covered in the is manual are
CTN
Description
PD32-EU
Power distro 3x32A, 230V, CEE 32A
PD30-US
Power distro 3x30A, 208V, NEMA L21-30
2.2 Intended Use
The PD30-US and PD32-EU mains power distributors are designed and dimensioned to provide and
distribute the mains power necessary to drive audio amplifiers, that feature a 32A powerCON®mains
power connector, in a system rack.
The PD30-US and PD32-EU may never be used outside a system rack or non-audio applications.

3.Mains In
PD30-US is designed for a mains supply network configuration of:
30 A 3øY 120/208 V~ VAC ~ 60 Hz
It has a NEMA 30A 3øY 120/208V VAC male connector that accepts the corresponding NEMA female
connector.
PD32-EU is designed for a mains supply network configuration of:
3-phase, 230/400 V~ -50/60 Hz –32 Amax.
It has a 32A CEE (Cekon) male connector that accepts the corresponding CEE female connector.
NOTICE! The main power distributor device has no built-in circuit breaker for the three
amplifier mains power lines. Protection is only provided by the onsite mains power sub-distribution.
DANGER! Potential Risk of electric shock!
The mains power distributor is a protective class 1 unit. A missing earth (ground) contact may cause
dangerous voltages in the housing and controls and may lead to electric shock.
Do not connect the NEMA/CEE mains connector under load or live!
Ensure the mains connector is accessible at any time to disconnect the unit in case of
malfunction or danger!
Connect the unit to mains power supplies with protective earth only!
If there’s any sign of obvious damage to the power cord and/or mains connector, do not use
the unit and replace it before further use!

When the rack is connected to onsite mains power supply, the three main indicators display the
presence of the onsite mains supply lines (phase conductors L1,L2,L3 on PD32-EU, X,Y,Z on PD30-
US).

4. Mains Outputs –Amplifiers
Both PD30-US and PD32-EU have three power lines that are terminated with a 32A powerCON®
(NAC3FC-HC) mains power connector. They appear on the rear panel and should be connected to the
three amplifiers.
Because there is no built-in circuit breaker, the amplifiers will be connected to mains power as soon as
the mains power connector is put on the mains power distributor.

5. Auxiliary Mains Outputs
The PD30-US, PD32-EU also feature three auxiliary mains outputs- on per phase. They are intended
for the connection of low current devices such as notebooks, or Ethernet switches.
They have 230 V~ / 16 A (PD32-EU), respect. 120 V~/ 15 A (PD30-US) circuit breaker on the front
panel. They are labeled:
