ble for the trouble-free operation of the instrument. When measuring
aggressive or corrosive media that can cause a dangerous situation
if the instrument malfunctions, the operator has to implement suitable
measures to make sure the instrument is functioning properly.
The safety instructions in this operating instructions manual, the na-
tional installation standards as well as the valid safety regulations and
accident prevention rules must be observed by the user.
For safety and warranty reasons, any invasive work on the device
beyond that described in the operating instructions manual may be

3.4 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging consists of environment-friendly, recyclable card-
board. For special versions, PE foam or PE foil is also used. Dispose
of the packaging material via specialised recycling companies.

damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
• Not in the open
• Dry and dust free
• Not exposed to corrosive media
• Protected against solar radiation
• Avoiding mechanical shock and vibration
• Storage and transport temperature see chapter " Supplement -
Technical data - Ambient conditions"
• Relative moisture 20 … 85 %

5.1 General instructions
Protect your instrument against moisture ingress through the following
measures:
• Use a suitable connection cable (see chapter " Connecting to
power supply")
• Tighten the cable gland or plug connector
• Lead the connection cable downward in front of the cable entry or
plug connector
This applies mainly to outdoor installations, in areas where high
humidity is expected (e.g. through cleaning processes) and on cooled
or heated vessels.
Note:
Make sure that during installation or maintenance no moisture or dirt
can get inside the instrument.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Note:
For safety reasons, the instrument must only be operated within the
ȽÊÅÁËËÁºÄ½ÈÊÇ»½ËË»ÇƼÁÌÁÇÆËƖÇÍ»¹ÆŲƼ¼½Ì¹ÁĽ¼ÁƾÇÊŹÌÁÇÆÇÆ
the process conditions in chapter " Technical data" of the operating
instructions or on the type label.
Hence make sure before mounting that all parts of the instrument ex-
posed to the process are suitable for the existing process conditions.
These are mainly:
• Active measuring component
• ÊÇ»½ËËŲÌÌÁÆ¿
• Process seal
Process conditions in particular are:
• Process pressure
• Process temperature
• Chemical properties of the medium
• ºÊ¹ËÁÇÆ¹Æ¼Ž»À¹ÆÁ»¹ÄÁÆŴͽƻ½Ë
As a standard feature, the VEGAPULS 6X is separate from the pro-
cess through its plastic antenna encapsulation.
Optionally, the instrument is available with a Second Line of Defense
(SLOD), a second process separation. It is located as gas-tight
leadthrough between the process component and the electronics.
This means additional safety against penetration of the medium fron
the process into the instrument.

The housing of VEGAPULS 6X can be rotated completely by 360°.
This enables optimal reading of the display and easy cable entry. 3)
For housings made of plastic or electropolished stainless steel, this is
done without tools.
For housings made of aluminium or stainless steel (precision cast-
ing), a locking screw must be loosened for turning, see the following
illustration:

Proceed as follows:
1. Loosen locking screw (hexagon size 2.5)
2. Turn housing into requested position
3. Re-tighten the locking screw (torque see chapter " Technical
data").
Note:
By rotating the housing, polarisation changes. For this reason,
please also observe the notes on polarisation in chapter " Mounting
instructions".
With the aluminium and stainless steel housing (precision casting),
the housing cover can be secured with a screw. This protects the
device against unauthorised opening of the cover.

Proceed as follows to secure the cover:
1. Screw the housing cover on tightly by hand
2. Unscrew the locking screw from the cover up to the stop using a

The housing cover is unlocked in the opposite way.
Note:
The locking screw has two holes drilled through the head. Thus it can
also be sealed.
5.3 Mounting preparations, mounting strap
The mounting bracket is supplied loose as an optional accessory for
the plastic horn antenna. It must be screwed onto the sensor with the
three M5 x 10 hexagon socket screws and spring washers before
setup:
• Required tool: Hexagon spanner size 4
• Max. torque: see chapter " Technical data"

2 Variant 1: Inclination steplessly adjustable
Depending on the selected variant, the sensor can be rotated in the
strap:
• Single chamber housing
– Inclination in three steps 0°, 90° and 180°
– Inclination 180° steplessly
• Double chamber housing
– Inclination in two steps 0° and 90°
– Inclination 90° steplessly

The optional mounting strap allows simple mounting of the instrument
on a wall, ceiling or boom. Especially in the case of open vessels, this

The following versions are available:
• Length 300 mm
• Length 170 mm
Note:
For safe operation of the device, stable, permanent mounting on a
load-bearing surface (concrete, wood, steel, etc.) is required. Take
this into account when choosing the installation location and use suit-
able fastening materials (screws, dowels, pipe clamps, etc.).
The instrument is normally mounted vertically with a bracket on the
ceiling.
This allows swivelling the sensor up to 180° for optimal orientation
and rotating for optimal connection.
