The loop amplifier is sent to you in a box. Refer to
table 3.1 for the contents of the box.
Install the loop amplifier in a 19-inch rack system or on
a flat surface (refer to figure 3.1).
Make sure that there is a free space of at least 100 mm
on both sides of the loop amplifier for ventilation. The
loop amplifier has a regulated internal fan, which keeps
the temperature of the electronics within the safe range.
