4. Transport, packaging and storage
4.1 Transport
Check the instrument for any damage that may have been caused by
transport.
Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property
can occur.
▶When unloading packed goods upon delivery as well as
during internal transport, proceed carefully and observe
the symbols on the packaging.
▶With internal transport, observe the instructions in chapter
4.2 “Packaging and storage”.
If the instrument is transported from a cold into a warm environment, the
formation of condensation may result in instrument malfunction. Before
putting it back into operation, wait for the instrument temperature and the
room temperature to equalise.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport
(e.g. change in installation site, sending for repair).
Permissible conditions at the place of storage:
Storage temperature: -20 ... +85 °C
Humidity: 0 … 85 %, not permanently condensing
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, humidity, dust and corrosive gases
■
Hazardous environments, ammable atmospheres

WARNING!
Physical injuries and damage to property and the
environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene,
ammable or toxic substances), harmful media (e.g. corrosive,
toxic, carcinogenic, radioactive), and also with refrigeration
plants and compressors, there is a danger of physical injuries
and damage to property and the environment.
Should a failure occur, aggressive media with extremely high
temperature and under high pressure or vacuum may be
present at the instrument.
▶For these media, in addition to all standard regulations,
the appropriate existing codes or regulations must also be
followed.
CAUTION!
Damage to the instrument
When working on open electric circuits (PCBs) there is a
risk of damaging sensitive electronic components through
electrostatic discharge.
▶The correct use of grounded working surfaces and
personal armbands is required.

DANGER!
Danger to life caused by electric current
Upon contact with live parts, there is a direct danger to life.
▶The instrument may only be installed and mounted by
skilled personnel.
▶Operation using a defective power supply unit (e.g. short-
circuit from the mains voltage to the output voltage) can
result in life-threatening voltages at the instrument.
▶Only switch the power supply on once the instrument has
been properly installed.
5.1 Mechanical mounting
Protect measuring instruments from contamination, high temperature
uctuations and vibrations. In order to avoid any additional heating,
the instruments must not be exposed to direct solar irradiation while
in operation.The ventilation duct temperature sensor can be fastened
directly to the ventilation duct using either a mounting ange or screws.
The IP65 protection is guaranteed, even without screwing down the case
cover. The temperature sensor is xed to the ventilation duct using the
mounting clip. If condensation could form in the thermowell, it is essential
to install it in such a way that any condensation can drain o.

40202798.03 04/2022 EN/DE/FR/ES/IT
WIKA operating instructions model A2G-60
Installation with a thermowell or compression tting is necessary when
used in liquid media. For better heat transfer from the thermowell to the
temperature sensor, thermal compound should be used.
5.2 Electrical mounting
Heat generation due to electrical dissipation loss
Temperature probes with electronic components always have an electrical
dissipation loss that aects the temperature measurement of the ambient
air. The dissipation loss occurring in active temperature probes increases
with rising operating voltage. This dissipation loss must be taken into
account in the temperature measurement. With a xed operating voltage
(±0.2 V) this is usually done by adding or subtracting a constant oset
value. Since the transmitters used work with a variable operating voltage,
only one operating voltage can be taken into account for production
engineering reasons.The 0 ... 10 V/4 ... 20 mA transmitters are set, as
standard, at an operating voltage of 24 V, i.e. at this voltage the expected
measured error of the output signal is lowest. At other operating voltages,
the oset error increases due to the changed dissipation loss of the probe
electronics. If recalibration is necessary directly at the probe during later
operation, this is possible using the trim pot on the probe board (for probes
with BUS interface, via a corresponding software variable).
If there are draughts, the dissipation loss at the probe is better
dissipated.This causes temporary deviations in the temperature
measurement.

5. Commissioning, operation
5.2.1 Temperature probe (passive)
The instruments are designed to operate with safety extra-low voltage
(SELV). When wiring up the instruments, the technical specications
for those instruments should be followed. Especially with passive
temperature probes (e.g. Pt1000, etc.) with a 2-wire system, the lead
resistance of the supply line must be considered. If necessary, this
must be corrected in the connected electronics. Due to self-heating, the
measuring current aects the measurement accuracy; therefore, this
should not be greater than 1 mA.
When using long connection cables (and depending on the cross-
section used), the measuring result might be falsied due to a voltage
drop on the common GND line (caused by the supply current and
the lead resistance). In this case two GND lines must be laid to the
temperature probe, one for the sense current and one for the measuring
current.

5.3 Transmitter (active)
In the case of a temperature sensor with transmitter, as a rule, the
transmitter should be operated in the middle of the measuring range,
since deviations can occur at the range limits.The ambient temperature
of the transmitter electronics should be kept constant. The transmitter
must be operated at a constant supply voltage (±0.2 V). Current/voltage
spikes from switching the supply voltage on or o must be prevented by
the customer. The measuring range is altered by changing the positions
of the jumper links (see connection diagram).The initial value of the new
measuring range is then available after approx. 2 s.
