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
especially when long power supply and signal cables are used.

voltage surges can cause damage to sensors and signal
Such
t description
conditioning instruments.
VEGA overvoltage arresters reduce 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.
Func
tional principle
Packaging
Transport
Transport inspection
Varistors (voltage-dependent resistors) as well as overvoltage arresters (gas arresters) are used as protective elements for voltage
limitation.
As soon as the voltage reaches the response voltage of the protective
element increases, it becomes conductive and dissipates the energy
by briefly bridging the supply cables. When the voltage surge
subsides, the protective element returns to high-impedance status and
has no further influence on the supply circuit.
Due to this protective concept of B61-300 FI without energy dissipation
to ground, a connected fault-current circuit breaker is not triggered.
3.3 Packaging, transport and storage
The device was protected by packaging during transport. Its capacity
to handle normal loads during transport is assured by a test according
to DIN EN 24180.
The packaging of standard instruments consists of environmentfriendly, 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 under 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
concealed defects must be appropriately dealt with.
Storage

Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the

3.4 Instal
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").

ecting to power supply
4.1 Preparing the connection
Always keep in mind the following safety instructions:
l Connect only in the complete absence of line voltage
Before starting setup make sure that the power supply corresponds to
the specifications on the type label.
For effective overvoltage protection, the cables between overvoltage
arrester and instrument should be as short as possible.
Dange
r:
Apart from the overvoltage arrester, a separate PE terminal is mounted
on the carrier rail in the aluminium housing. It is galvanically connected
with the carrier rail.
The ground conductor (PE) of the power supply cable must be led to
this PE terminal to reach protection ground for the aluminium housing.
The PE terminal on the overvoltage arrester must be free.
In
hazardous areas you must take note of the respective regulations,
conformity and type approval certificates of the sensors and power
supply units.
4.2 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, N and PE according to chapter "Wiring
plan" to the terminals of the overvoltage arrester
4 With aluminium housing connect the wire end for PE to the green/
yellow PE terminal in the housing
5 Check all cable connections, especially the PE connection, to
make sure they are tightened sufficiently
6 Tighten the compression nuts of the cable glands. The seal ring
must completely encircle the cable
7 Tighten screws of the housing cover
The electrical connection is finished.

5.1 Maintenance
If the instrument is used properly, no special maintenance is required
in normal operation.
5.2 Fault rectification
The operator of the system is responsible for taking suitable measures
to rectify faults.
The first measure to be taken is to check the input/output signal as well
as the power supply. In many cases, the causes can be determined
and faults can be quickly rectified.
On-site repair of B61-300 FI is not possible.
Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no. +49 1805 858550.
The hotline is available to you 7 days a week round-the-clock. Since
we offer this service world-wide, the support is only available in the
English language. The service is free of charge, only the standard
telephone costs will be charged.
Depending on the failure reason and measures taken, the steps
described in chapter "Set up" must be carried out again, if necessary.
