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 signal condi-
tioning instruments.
VEGA overvoltage arresters reduce voltage surges on the supply or
signal cables to a safe level.They are designed for mounting on car-

rier 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,dierent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inuence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 humidity 20 … 85 %

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.
The carrier rail inside the housing is galvanically connected to the
ground terminal outside on the housing. For this function of the over-
voltage arrester, this ground terminal must be connected (low imped-
ance)withthepotentialequalizationline(PA).Thewirecross-section
must be at least 2.5 mm2, the cable must be as short as possible.
