2.3 Warning about incorrect use
Inappropriate or incorrect use of this product can give rise to applica-
tion-specic hazards, e.g. vessel overll through incorrect mounting
or adjustment. Damage to property and persons or environmental
contamination can result. Also, the protective characteristics of the
instrument can be impaired.
2.4 General safety instructions
This is a state-of-the-art instrument complying with all prevailing
regulations and directives. The instrument must only be operated in a
technically awless and reliable condition. The operator is responsi-
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
carried out only by personnel authorised by the manufacturer. Arbi-
trary conversions or modications are explicitly forbidden. For safety
reasons, only the accessory specied by the manufacturer must be
used.
To avoid any danger, the safety approval markings and safety tips on
the device must also be observed.

the Canadian Electrical Code.
2.8 Environmental instructions
Protection of the environment is one of our most important duties.
That is why we have introduced an environment management system
with the goal of continuously improving company environmental pro-
tection. The environment management system is certied according
to DIN EN ISO 14001.
Please help us full this obligation by observing the environmental
instructions in this manual:

3.2 Principle of operation
Voltage surges can be caused by indirect atmospheric discharges
(lightning strokes) or switching operations in the supply network.
Further causes can be inductive or capacitive couplings from other
electrical systems. Voltage peaks (transients) must be expected espe-
cially when long power supply and signal cables are used.

B62-30W • For Probus PA and Foundation Fieldbus circuits
40492-EN-220516
Such voltage surges can cause damage to sensors and controllers.
The VEGA overvoltage arrester reduces voltage surges on the supply
or signal cables to a safe level. They are designed for mounting on
carrier rail according to EN 50 022/EN 50 035 in the switching cabinet
or in a metal or plastic housing close to the sensor.
Depending on the version, dierent combinations of protective ele-
ments for voltage limitation are used. Typical protective elements
are suppressor diodes (diodes with special characterstics), varistors
(voltage-dependent resistors) as well as overvoltage arresters (gas
arresters).
As soon as the voltage increases to the response voltage of the
protective element, the element becomes conductive and the energy
is discharged to ground. After the overvoltage has subsided, the
protective element returns to its high-impedance state and thus has
no inuence on the supply or signal circuit.
3.3 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 of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
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 %
With instrument weights of more than 18 kg (39.68 lbs) suitable and
approved equipment must be used for lifting and carrying.

4 Mounting instructions
4.1 Installation in switching cabinet
The overvoltage arrester is mounted in the switching cabinet on
carrier rails according to EN 50 022 (DIN rail) or EN 50 035 (C-rail). It
is fastened to the carrier rail with a screw located on its exterior. The
screw is marked with the symbol for functional ground. Depending on
the version, it may be galvanically connected to the ground terminal
of the overvoltage arrester (see circuit diagram in chapter " Wiring
plan").
The carrier rail must be connected (low impedance) to the potential
equalization line (PA). The wire cross-section must be at least 2.5
mm2, the cable must be as short as possible.

4.2 Mounting in housing
The overvoltage arrester is optionally available in a plastic or alu-
minium housing. Make sure when mounting that the cable glands
point downward. Thus avoids water ingress.
