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.
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.
Dependingontheversion,dierentcombinationsofprotectiveele-
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
noinuenceonthesupplyorsignalcircuit.
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
equalizationline(PA).Thewirecross-sectionmustbeatleast2.5
mm2, the cable must be as short as possible.

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.

5 Connecting to power supply
5.1 Preparing the connection
Always keep in mind the following safety instructions:
• Connect only in the complete absence of line voltage
Before starting setup make sure that the power supply corresponds to
thespecicationsonthetypelabel.
Foreectiveovervoltageprotection,thecablesbetweenovervoltage
arrester and instrument should be as short as possible.
5.2 Connection steps for version with housing
Proceed as follows:
1. Loosen screws of the housing cover
2. Push the supply and connection cables through the cable gland
into the housing, strip approx. 1 cm (0.4 in) insulation from the
ends of the wires
3. Connect the wire ends according to chapter " Wiring plan" to the
terminals of the overvoltage arrester
4. Connect the outer ground terminal on the housing to potential
equalization
5. Check all cable connections, especially the ground connection, to
makesuretheyaretightenedsuciently
6. Tighten the compression nuts of the cable entry glands. The seal
ring must completely encircle the cable
