INSTALLATION AND OPERATING INSTRUCTIONS
1.0 Important information
In order to ensure complete and effective
operation and for your own safety, all of the
following instructions should be read carefully
and observed.
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 product-related
safety regulations must be observed.
These installation instructions cannot
take all installation, operating and
maintenance conditions into account. You
can obtain further information from your local
dealer or the product data sheet, which can
be downloaded on the Internet.
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.
mThe 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 product-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 PSDpower 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 qualication
m DANGER!
The electrical connection and start-up must only
be carried out by qualied electricians.
Installation, servicing and maintenance of the
fan must only be carried out by qualified
electricians. Unohab individual room ventilation
units can be used by children over the age of
8 as well as persons with physical, sensory,
or mental disabilities or lack of experience
and knowledge, if they are supervised or
instructed with regard to the safe use of the
unit and they understand the resulting risks.
Children must not play with the unit. Cleaning
or user maintenance must not be carried out by
children.

3.0 Installation
-During operation, the power supply unit must
not be accessible.
- A suitable flameproof casing must be
provided in the end product.
-Sufficient cooling must be ensured.
-The maximum surface temperature must not
be exceeded.
Note: Electrical damage
Connect a thermomagnetic fuse for device
protection. Horizontal mounting (Input AC
terminal block at the bottom).
Minimum gap for convection: 3 cm above and
below.
The connection can be made via the connecting
wires with suitable terminals.
3.1 Electrical connection / start-up
mDANGER
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
signicant 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.
m Attention!
The input and output cables must be installed
so that they are clearly separated from one
another.Install the cables without twisting.
The cables must not cross each other and
must be shortened accordingly.
All wiring terminals must comply with DIN
EN 60998.
508: Copper cable; operating temperature
>75°C (ambient temperature<55°C) and >90°C
(ambient temperature<75°C).
ANSI/ISA 12.12.01: A. Note: The power supply
unit is suitable for use in Class I, Division 2,
Groups A, B, C, and D or in non-potentially
explosive areas.
B. Note - Explosion hazard-Substitution of
components may impair suitability for use in
potentially explosive areas (Class I; Division 2).
C. Note - Explosion hazard-Only remove
equipment when the power is disconnected or
the equipment is not in a potentially explosive
area.
