(A)
(B)
 An additional strain relief is not necessary because the cable has a max. tensile
strength of 1000 N (500 N with FEP).
 The protection cap (A) protects the secluded diaphragm (B) from damaging the
level probe during transport and immersion. Remove the protection cap if used with
viscous or contaminated media.
Protect the diaphragm against any contact with abrasive substances and

pressure peaks and do not touch it with tools. If you damage the diaphragm,
no intrinsic safety can be guaranteed (ATEX, FM, CSA)!
Warning
Observe the technical data for the use of the pressure transmitter in connec-

tion with aggressive/corrosive media and for the avoidance of mechanical
hazards.

7. Starting, operation
Installation in / mounting to zone 0 and zone 0
(In general Zone 0 is given when the pressure transmitter is surrounded by a mixture of explo-
sive gases more than 1.000 hours per year = continuous hazard).
Include the screen/sheath of the connection line used as a suspension rope

in the equipotential bonding of the container.
 For seperation of the zones the bulkhead cable gland in the wall must have
Warning
the ingress protection according to IEC 60 529 namely for zone 0: IP 67 and
for zone 20: IP 6X.
 Integrate an overvoltage protection, if the mounting position is less than 1 m
away from the transition into Zone 0.
Electrical connection
 Ground the cable screen at one end, preferably in the safe, thus non-Ex,
area (EN 60079-14). For devices with flying leads, the screen is connected
to the housing. The simultaneous connection of housing and cable screen
Warning
to ground is only permitted if ground loop problems between the screen
connection (e.g. at the power supply) and housing can be excluded
(see EN 60079-14).
If the housing of the transmitter is not grounded and is likely to be subjected

to any electrostatic charging (EN 600079-14, 6.3 Paragraph 4) or if the level
probe is to be operated in Zone 0 (DMT 00 ATEX E 045 X), the cable screen
should be connected to the equipotential bonding.
Supply the level probe from an intrinsically safe current circuit (Ex ia).

Consider both the internal capacitance and inductance.

Cover flying leads with fine wires by an end splice (cable preparation).

Consider that cables for use in zones 1 and 2 must be checked with a test voltage

between conductor/earth, conductor/screen of more than 500V (AC).
