INSTALLATION
The device can be installed in any position. In case of an horizontal or titled
installation, mount the device with the cable entrance on the right side for
PFG05L models, or lower side for PFG57L models. The coupling of the
instrument with the wall of the container (silos) can be either threaded or
anged; images 2 and 3 show the standard couplings. Always refer to the
technical drawings supplied by the Manufacturer together with this manual.
Protect the device from falling material or excessive weight, using protective
deectors. For cable entries, 1 (one) or 2 (two) G 1/2 threaded holes (BSPP) are
available. Seal the cable entries with cable glands or sealing caps suitable for
the operating range shown on the label.
The protective caps supplied with the device are only for protection during
transport and storage, they are not suitable for the use of the instrument and it is
responsibility of the installer to replace them.
The diameter of the power supply cable must correspond to the tightening range indicated by the cable gland used.
