3 Product description
B62-36G • For supply and signal cables in 4 … 20 mA circuits
40491-EN-220516
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, different 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 influence 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
•
