EXTERNAL CONNECTIONS INSTALLATION
PREMISE
The rear cable glands must be used correctly in order to avoid malfunction and/or premature discharge
of the batteries. In bad use, the device's IP54 protection can no longer be considered valid. The cables
must be proportionate to the size of the hole made to pass them. The manufacturer does not assume
any responsibility for improper installation or damages caused by third parties.
For a good use of the rear cable glands, it's necessary to perform a small hole and gently push the cables
to be inserted from the bottom to the other so that the sheath hermetically closes on them. This will
ensure good insulation from external agents such as dust, heat and humidity.
In the examples below, the incorrect use of cable allows the passage of moisture and dust, which, over
time, could lead to a relative increase in consumption on the electronic board in the installed devices.
The IP54 protection of the device is NO longer valid.
