4. INSTALLATION AND ELECTRIC CONNECTION
Place of installation should be selected so that proper place should be available for handling.
Gauges measuring gases should be mounted to the highest point, liquids to the lowest points of the tank or pipe.
GASES LIQUIDS
Devices should not be installed to places with pressure waves involved for instance by
stirrer or pumps.
Device should be protected from direct heat (sun) radiation.
Front diaphragm must not be pressed by hand or any object or cleaned with hard tool.
Diaphragm protection cap can only be removed before installation!
Devices with thread should be tightened with open-end wrench to the maximum torque
of 35 Nm.
After tightening the transmitter the rotatable housing can be rotated so that the cable
gland will look down which is especially suggested in open air applications.

4.1 WIRING
Transmitters are used in 2-wire systems with power supply of
10…36 V DC. Resistance of the units in the loop depends on the voltage of the
power supply.
For wiring shielded cable suggested in the Technical Data should be used.
After removal of the housing cover and taking out the display module (if any), the
screw terminals can be accessed. Cover of the flame proof housing can be
removed after unhooking the clamp.
The unit should be grounded by the inner or outer grounding screw.
Switch on the unit and make necessary programming.
After programming ensure proper sealing and closing of the cover (and fastening
of the clamp with the flame proof models).
The unit may be damaged by electrostatic discharge (EDS) via its terminal, thus apply the precautions commonly used to avoid electrostatic
discharge e.g. by touching a properly grounded point before removing the cover of the enclosure.
4.2 SPECIAL CONDITIONS FOR SAFE USE
Intrinsically safe units can only be used in certified intrinsically safe loops with the
previously given technical data. (see values in Technical data table under Point 3.1).
Devices should be grounded by connecting their grounding screws to the equipotential
system.
Equipment with plastic housing can be loaded electrostatically therefore the devices
must be protected against electrostatic charges. The housing is allowed to clean only
with wet rag.
Since the housing of the units is made of die cast aluminium, when the units are
installed into a location which requires ‘Ga’ protection level, the units should be
mounted that they are protected against impacts and friction effects which may be
source of a potential ignition.
