4.1. PLACING THE UNIT
Place the unit at the right position and height.
Avoid direct sun exposure, humidity, dust and vi-
brations.
Avoid proximity to any source of interference
which could affect the correct operation of the unit.
The A-4000 is made up
of just one piece, except the
built-in models with more
than 32 outputs, which go
with a second box.
In the “built-in model”, a
hole is to be done in the fron-
tal part of the wall or desk,
according to the measures in the section DIMEN-
SIONS. It will be held with the screws of the corners,
using the four pieces which are included in the unit.
The wardrobe must have a double isolation with
protection for the operation relationship to the net
power supply circuit.
In the “box” model, the unit is held by the upper
pieces at the corners and by the two holes placed at
the below cover of the connection housing, according
to the measures shown in the section DIMENSIONS.
In the version with “box”, the equipment is pro-
vided in a hermetically sealed (box IP65) with a trans-
parent front cover for the keyboard/display and an
opaque cover for the connection housing.
In order to maintain isolation of the box it is nec-
essary to maintain the covers always closed, as well
as install grommets at the outputs of the cables.
