2. INSTALLATION
2.1.4. Vibrations
The instrument can support vibrations from 10 to 55 Hz,
20 m/s
2
, in all directions (X, Y and Z).
If the device is mounted on a support that exceeds these
limits, it is recommended to provide a suspension system to
reduce vibrations.
2.1.5. Minimum space for ventilation
The temperature in the housing containing the instrument
must NEVER exceed 55°C. NEVER block the ventilation slits.
Advice. The lower the temperature in which the de-
vice works, the longer the life of its electronic com-
ponents.
Attention! Forced cooling (for example, with a fan)
of the rear of the instrument may cause measure-
ment errors.
2.1.6. Positioning
The indicator 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 reflecti-
ve screen. The instrument must be tilted between 30° and
120°, as shown in the figure.

2.1.7. Fastening to the panel
1. Insert the die-cut rubber gasket between the instrument
and the panel. The gasket (supplied) is required for en-
suring 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 instru-
ment.
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 °
30 °
