Before connection, please note the following:
The power supply must be identical to the data on the
nameplate (1).
Switch off power supply before connecting up the device.
Connect Equipotential bonding to transmitter ground
terminal before connecting up the device.
Tighten the locking screw:
It forms the connection between the antenna and the
housing ground potential.
When you use the measuring system in hazardous areas, make sure you comply with
national standards and the specifications in the safety instructions.
Make sure you use the specified cable gland.
Caution!
Connect the as follows:
Insert cable (3) through gland (4).
Use screened, twisted 2-wire or 4-wire cable.
Make connection (see pin assignment).
Tighten cable gland (4).
Screw of f housing cover (2).
Switch on power supply.

possibly in combination with other devices - connected
to a tank side monitor in a hazardous area. In this case, it is recommended
that you ground the cable screen centrally at the TankSide Monitor and
connect all devices to the same potential matching line (PML). If, for functional
reasons, a capacitive coupling is required between local earth and screen
(multiple grounding), ceramic condensers with a dielectric strength of min. 1500 V
must be used, whereby the total capacitance of 10 nF must not be exceeded.
Notes on grounding interconnected intrinsically safe devices are provided by
the FISCO model.
