- S2 24V DC

By attaching the drive to a movable
element of the window and connecting
it to a power supply a so-called
“power-operated window” is created
which, according to the Machinery
Directive 2006 / 42 / EG, represents a
machine.

Pay attention to possible hazards on
tilting or rotating windows, whose
side closing edges (NSK) are located
at less than 2,5 m installation height
above the fl oor, under consideration of
the Control Unit and usage!

Area of application / Scope of application

This drive is intended for the electromotive opening and
closing of windows in facade or roof areas.

The main task of this product

, in combination with

a window and a suitable external control unit,

is to

evacuate hot smoke and combustion gases in case
of fi re

, to safe human lives and protect material

assets. Furthermore, with the electromotive operated
window and a suitable external control unit,

the natural

ventilation

of the building can be ensured.

Intended use

The drive is intended for stationary installation and
electrical connection at the window as part of a building.
The drive is in combination with an external Control Unit
(e.g. from

UMÜlleR

) released for its proper use at a

power-operated window for the following use:
• Application for natural ventilation



with an installation height of the drive and

the bottom side of casement of at least 2,5 m above
the

oor,



with an opening width at the HSK of the driven

    part of < 200 mm by a simultaneous speed of
    < 15 mm/s at the HSK in closing direction.
•  Application as NSHEV (natural smoke and heat
  exhaust ventilator(s) in accordance with EN12101-2
  without dual purpose for ventilation.

The need for a risk assessment at the installation site
due to the reasonably foreseeable misuse.
A risk assessment in accordance with the Machinery
Directive 2006 / 42 / EG

for the usage of the power-

operated window

for natural ventilation is absolutely

necessary

under the following conditions:

• the installation height of the drive and lower edge
of casement < 2,5 m above the fl oor

and

one of the following conditions:

• the opening width at the HSK is > 200 mm,

• the closing speed at the HSK is > 15 mm/s,

• the opening speed at the HSK is > 50 mm/s,

• the closing force at the HSK is > 150 N
The following fl ow chart can be applied, which also includes
the protective measures in accordance with EN 60335-2-
103/2016-05.

We as manufacturers are well aware of our duties and
responsibilities regarding the development, manufactu-
ring and placing of safe window drives on the market and
consistently implement them. Ultimately, however, we have
no direct infl uence on the usage of our drives. Therefore,
as a precaution, we point out the following:

• The

constructor or his agent

(architect, specialist

planner)

are obligated

to evaluate the

hazards to persons

, outgoing from the usage,

installation position, opening parameters and from the
external Control Unit of the power operated window,
already

in the planning phase and to establish

necessary protective measures

• The
