This document should be regarded as part
of the product and as such should be kept
accessible and durable to ensure the safe
operation of the fan. All p
roduct
-related
safety regulations must be observed.
These installation instructions cannot
take all
i
nstallation, operating and
maintenance conditions into account. You
can obtain further information from your local
dealer or the product data sheet, which can

1.1 SAFETY INSTRUCTIONS
Special regulations apply for use,
connection and operation; consultation
is required in case of doubt. Further
information can be found in the relevant
standards and legal texts.
m
The following points must be
observed before any cleaning,
maintenance and installation work:
• Isolate device from the mains power
supply and secure against being
switched on again!
• After switching off, a waiting time
of 5 min. must be observed, as
dangerous voltages may be present
after disconnection from the mains due
to internal capacitors!
• Non-observance, touching live electrical
parts or improper use of this power
supply unit can result in death, serious
injuries or significant material damage.
• All p
roduct
-related safety reg
.
must
be
observed! Further country-specific
regulations must also be observed.
1.2 Application
This compact, fully encapsulated switching
power supply is solely designed as a
decentral power supply for the
Unohab
unit for
installation
in a
DIN rail.
Further information can be found in section 3.0
“Installation”.
– Normal use:
The
Unohab
PS
D
power supply unit is only
approved for fixed installation inside buildings in
a
DIN rail
. The maximum permissible
ambient
temperature can be found on the type
plate.
– Reasonably foreseeable misuse:
The power supply unit is not suitable for
operation under difficult conditions, such as
high levels of humidity, aggressive media,
long standstill periods, heavy contamination,
excessive loads due to climatic, technical or
electronic influences. The same applies for the
mobile use of fans (vehicles, aircraft, ships,
etc.). Usage under these conditions is only
possible with release approval from Airflow, as
the standard version is not suitable in this case.
– Improper, prohibited use:
Any use other than the intended use is not
permitted! The conveying of solid matter or
solid matter content > 10µm in air and liquid is
not permitted!
1.4 Personnel qualification
m
DANGER!
The electrical connection and start-up must only

wires with suitable terminals.
3.1 Electrical connection / start-up
m
DANGER
Touching live parts will result in electric
shock. Only connect with no voltage
present!
– The electrical connection and initial start-up
are to be carried out in accordance with the
relevant wiring diagrams and are only to be
carried out by a certified electrician.
– The relevant standards, safety regulations
(e.g. DIN VDE 0100, EN 50178), as well
as the technical connection conditions of
energy suppliers are to be adhered to!
– A multipole mains section switch/isolator, with
a
minimum contact opening of 3 mm (VDE
0700 T1 7.12.2 / EN 60335-1) is mandatory!
– The power supply and the supply network
must be sufficiently fused.
–
The network connection must comply with IEC
62103, EN 50178 and IEC 60364, VDE 100.
– The supply
cable
must be introduced, so
that
no water can get in along the cable in
case of
water exposure.
–
Network configuration, voltage and
frequency
must be consistent with the rating
plate
information.
– Never work on the power supply unit when it is
live! There is a risk of electric arcs and electric
shock which can result in death, serious
injuries or significant material damage.
m
Warning:
Dangerous voltages and components with
significant amounts of stored energy may
be present during normal power supply unit
operating conditions. However, they are not
accessible.
Improper use can result in electrical shock
or significant burns! Keep away from fire
and water!
The power supply unit must be connected
according to
Fig. 3
