Mains connection
The device may only be connected to an electrical installation that complies with the VDE regulations DIN VDE 0100.
The electrical installation must be equipped with a residual current circuit breaker (RCD) with> 30mA rated residual
current.
The devicve is supplied with dangerous mains voltage (>50 Volt AC). Therefore never intervene on the device on
yourself! There is a risk of electric shock! Connection cables has to be protected against crushing, tensile load and
bending. Cables and wires are to be laid or secured in such a way that no one can trip over it or may fall.
Damaged Mains-Power cables
must not be used and should immediately be rendered unusable against further use,
e.g. cut off both plugs.
The device is powered by a Neutrik Powercon® connector. In contrast to a plug-in device (such as a safety plug), the
Powercon® plug-in connection must not be plugged in or disconnected under load and also not under voltage! The
consequences are stuck or burned-out contacts and the resulting loose contacts lead to failures or even destruction
of the electronics or even the risk of fire. You should therefore only switch the device ON or OFF using the
2-pole power switch on the front panel of the unit.
The mains plug may only be connected to an earthed safety socket with the associated mains connection cable. If
extension cables are used, it must be ensured that the wire cross-section is dimensioned and approved for the
power supply required for the device! Make sure that the mains voltage of the socket corresponds to the permissible
voltage values
in
this manual.
The power supply of the amplifier is equipped with an intelligent mains voltage detection. It allows worldwide
operation on all power grids. After switching on, the electronics check the mains voltage and switches the power
pack to the correct voltage range 115V AC or 230V AC.
If a three-phase current generator is used at events on which the device is to be operated, the correct mains
voltage must be checked before connecting the amplifier! In the event of faulty three-phase power supplies
without a neutral conductor, a so-called neutral point shift can result in up to 400Volt being applied to the
protective contact sockets. This overvoltage leads to the destruction of the electronics in the amplifier.
The device has a PowerCon®-Out (16) over the existing Powercon®-IN (17). This is provided for the option of
connecting another device through a short interlink PowerCon®-cable eg. when built in in a rack with other amplifiers
or other devices. Please make sure that the overall power consumption of all connected devices does not exceed the
maximum power of 16 Ampere, or the maximum allowed power limited by the upstream line circuit breaker.
Please refer to the technical data for detailed information regarding power consumption of the PowerPac 4003 DSP.
Best option is to connect the PowerPac 4003 DSP to its own circuit with a 16A fuse (characteristic curve C).
Please refer to the technical data for the power consumption in the different operating states.
The device corresponds to protection class 1.
In the event of a thunderstorm or danger, pull the power plug out of the socket immediately.
To avoid ground loops, we recommend using symmetrical signal routing and the power distribution in the so-called
star point earthing, which means, all ground connections meet at one single point.
Never interrupt the contact to the protective conductor (e.g. by cutting off the protective conductor, disconnecting
the connection to the protective conductor through insulation, etc.), because in the event of a defect this increases
the risk of a electric shock over the metal housing.
