3. INSTALLATION
3.1. Placement and mounting
The AMPACK series offers a huge variety of installation
possibilities as p.eg:
•
Installation on 35mm DIN rail
•
Desktop installation using the included accessories.
•
False ceiling / partition wall: this accessory allows fixing the unit
using screws or flanges prepared for this usage.
3.2. Mains connection
The amplifier is powered with alternate current, 220-240V 50/60Hz. The maximum power
consumption is 296VA for the AMPACK80 and 93VA for the AMPACK25. The power installation has to
be able to deliver these power values.
The amplifier should have an earth connection in good conditions (earth resistance, Rg=30
Ω
or less). The environment must be dry and dustless. Do not expose the unit to rain or water splashes,
and do not place liquid containers or incandescent objects like candles on top of the unit. Do not
obstruct the ventilation grids with any kind of material.
In case there is some type of intervention and/or connection-disconnection of the amplifier, it
is most important to previously disconnect the mains power supply. There are no user or serviceable
parts inside the amplifier.
You should avoid that the supply cable twists with the shielded signal cables, as this could
lead to unwanted hum.
The indicated situations can produce hum noise. To avoid this, the AMPACK series wears an
additional high pass filter with fixed cut-off frequency at 100Hz. This filter can be easily activated using a
jumper as shown on the configuration diagram.
In order to protect the unit from an eventual electrical overload or momentary power peaks
from the internal circuits it carries a fuse. Should it ever blow up, unplug the unit from mains and
replace it with an identical one. If the new fuse blows again contact immediately with our Authorized
Technical Service.
CAUTION: YOU MUST NEVER USE A HIGHER VALUE FUSE.
