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.

B 61-300 FI • For supply and signal cables with leakage circuit breaker
40489-EN-220516
Varistors (voltage-dependent resistors) as well as overvoltage ar-
resters (gas arresters) are used as protective elements for voltage
limitation.
As soon as the voltage reaches the response voltage of the protec-
tive element increases, it becomes conductive and dissipates the
energybybrieybridgingthesupplycables.Whenthevoltagesurge
subsides, the protective element returns to high-impedance status
andhasnofurtherinuenceonthesupplycircuit.
Due to this protective concept of B61-300 FI without energy dis-
sipation to ground, a connected fault-current circuit breaker is not
triggered.
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").

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.This ground terminal can be
connectedwiththepotentialequalizationline(PA).Forthefunctionof
the overvoltage arrester, however, this is not necessary.

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
thespecicationsonthetypelabel.
Foreectiveovervoltageprotection,thecablesbetweenovervoltage
arrester and instrument should be as short as possible.
Danger:
Apart from the overvoltage arrester, a separate PE terminal is
mounted on the carrier rail in the aluminium and plastic housing. It is
galvanically connected with the carrier rail.
On the aluminium housing, the ground conductor (PE) of the power
supply cable must be led to this PE terminal to reach protection
ground for the metal housing.
Note:
Install a disconnecting device for the instrument which is easy to
access.The disconnecting device must be marked for the instrument
(IEC/EN 61010).
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 L and N according to chapter " Wiring
plan" to the terminals of the overvoltage arrester
4. Wire ends for PE to the green/yellow PE terminal in the housing
5. Check all cable connections, especially the PE connections, to
makesuretheyaretightenedsuciently
6. Tighten the compression nuts of the cable entry glands. The seal
ring must completely encircle the cable
7. Tighten screws of the housing cover
Theelectricalconnectionisnished.
