Vibrations
The controller can support vibrations from 10 to 150 Hz,
20 m/s2 (2 g),in all directions (X, Y and Z).
If the device is mounted on a support that exceeds these
limits, it is advisable to provide a suspension system to
reduce vibrations.
2.1.5.
Minimum space for ventilation
The temperature in the housing containing the controller
must NEVER exceed 55°C.
NEVER block the ventilation slits.
Advice. The lower the temperature in which the
device works, the longer the life of its electronic
components.
Attention! Forced cooling (for example, with a fan)
of the rear of the controller may cause measurement
errors.
2.1.6.
Positioning
The controller must be positioned so that the display is not
subject to direct sunlight or to very strong sources of light.
If necessary, filter direct light, for example, with a reflective
screen.
The controller must be tilted between 30° and 120°, as
shown in the figure.

Fastening to the panel
1.
Insert the die-cut rubber gasket between the controller
and the panel. The gasket (supplied) is indispensable for
ensuring the declared protection index of the faceplate.
2.
Insert the device into the hole previously made on the
panel.
3.
Place the supplied bracket(s) onto the rear of the con-
troller.
4.
Tighten the screws to fasten the device to the panel.
The tightening torque must be between 0,3 and 0,4 N m
120 °
