3.2 Cooling
Minispeed amplifier should be
installed to allow a proper heatsink
cooling.
Only position accepted in the
equipment is vertical mounting.
It is important, for proper natural convection cooling, avoid to put other objects above
the amplifier.
Using the amplifier in dusty ambient,it is important that the doors of boxes containing
electronic equipment be kept closed and air must be filtered avoid the entry of contaminants
and conductive particles wich can cause extensive damages.
Every amplifier is provided with a thermoswitch that opens when the temperature exceeds
a safe operating level,S.T. protections will be memorized.
The fault canʼt be reset.We must wait until the heatsink temperature is lower.
If we use intensively the amplifier with high room temperature ambient and quick step
we must provide for forced cooling.
NOTE: In case of forced cooling requirement the ventilator it should be installed at the
bottom of the amplifier under the relative units.
Max. Ambient temperature C°
NOTE
3.3 Wiring
Minispeed amplifier has several wiring connections which must be made in order to ensure
the correct operation for reduce interferences.
Use shielded cable for analogue and tacho signal.(For wiring connections see page 20)
Signals cables must be not togheter power wires signals cable output should be own
upper side power wiring output twisted togheter should be on lower side.
AXOR advise:
0,5 / 1 mm2 for signal cables, 2 mm2 for power cables MS 4/8A e 8/16A , 2,5 / 3 mm2
for power cables MS 10/20A e 14/28A, 4 mm2 for power cables MS 20/40A and 25/50A.
