External housing • VEGAFLEX 80 series
46802-EN-200212
Depending on the order, the screwed cover of the instrument housing
is available with or without inspection window for the display and
adjustment module PLICSCOM.
TheHFconnectioncableoftheexternalhousingcaninuencethe
measurement properties of VEGAFLEX. If the length of the sensor
exceeds the length of the HF connection cable, the min. dielectric
constanthastobeεr> 2, independent of the instrument version. If the
HF connection cable is longer, there are no limitations.
3.2 Principle of operation
The external housing is suitable for the following plics®sensors:
• VEGAFLEX 81
• VEGAFLEX 82
• VEGAFLEX 83
• VEGAFLEX 86
Theexternalhousingcannotberetrotted.
3.3 Storage and transport
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 outer packaging of standard instruments consists of environ-
ment-friendly, recyclable cardboard. PE foam or PE foil is also used
for packing the instrument. Dispose of the packaging material via
specialised recycling companies.

4.1 General instructions
In the following cases, we recommend using an instrument version
with external housing:
• if the standard housing is too big
• if strong vibrations can damage the electronics
In Ex applications, only housings with appropriate Ex approval may
be used.
4.2 Mounting preparations
The following tools are required for mounting the external housing.
Instrument housing:
• Hexagon socket wrench, size 4
• Fork wrench, wrench size 19
Sensor housing:
• Fork wrench, wrench size 8
• Fork wrench, wrench size 19
We recommend using additional materials when mounting the wall
mounting plate.
• 4 screws, depending on the mounting surface
4.3 Mounting steps - instrument housing
1. Mark the holes according to the following drilling template
2. Depending on the mounting surface, fasten the wall mounting
plate with 4 screws

4 Mounting
External housing • VEGAFLEX 80 series
46802-EN-200212
Tip:
Mount the wall mounting plate in such a way that the cable gland of
the base points downward. Rain and condensation water can thus
draino.
The base of stainless steel can be displaced in 90° increments on the
wall mounting plate, the base of plastic by 180°.
Turn the cable gland of the electronics housing downward.The hous-
ing can be turned by 330° without the use of any tools.
Warning:
With the plastic housing, the four screws of the base may only be
screwedinhandtight.Exceedingthemax.torquespeciedinchapter
"Technical data" can damage the wall mounting plate.
4.4 Mounting - sensor housing

5 Connect the sensor to the external
housing
5.1 Preparing the connection
Follow the instructions in the operating instructions manual of the
sensor.
5.2 Connection procedure
Note:
Only use the corresponding HF connection cable in the correct
length.
Make sure that the markings (serial no.) correspond on the individual
parts (sensor housing, instrument housing and HF connection cable).
The assembled HF connection cable has a straight N-plug on one
end and an N-angled plug on the other. Both plugs can be connected
to any side.
1. Remove the protective cover on the plug connector of the sensor
housing.
2. Insert the plug (straight plug or angle plug) of the HF connection
cable into the sensor housing and hand-screw the hexagon nut.
3. Tighten the hexagon nut of the plug with the fork wrench (SW 19)
with max. 3 Nm (2.212 lbf ft).
4. Secure the hexagon nut of the plug with the securing strap. For
this purpose, place the securing strap on one surface of the hexa-
gon nut and tighten it with an Allen key (size 4).
