Connect up the Micropilot S as follows:
Before unscrew housing cover (2) at seperate connection room
turn off the power supply!
Insert cable (3) through gland (4).
Use screened, twisted 2-wire or 4-wire cable.
Only ground screening of the line (5) on sensor side.
Make connection (see pin assignment).
Tighten cable gland (4).
Screw off housing cover (2).
Switch on power supply.

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

The power supply be delivered by a transmitter supply unit.
When you use the measuring system in ha
z
ardous areas, make sure you comply with
national standards and the specifications in the safety instructions (XA’s).
Make sure you use the specified cable gland.
Caution!
"
A Micropilot S situated in a ha
z
ardous area is connected as a
to a
situated outside of the
ha
z
ardous area. In this case, it is recommended that the screen be
connected directly to the Micropilot at the housing's earth, whereby
the Micropilot S and the power supply unit are connected to the same
potential matching line (PML).
