The installation and operating instructions must be read prior
to installation and then duly followed. Any failure to do so absolves
the manufacturer of any liability.
1.1. Safety and warning notes for the installation instructions
Safety notes can be found throughout the text. They are marked
with various symbols and text:
Important safety note:
Notes that are important for the functioning of the product and can
result in serious injury or death if they are not observed are marked
with this warning triangle.
Important safety note:
Notes that are important for the functioning of the product and
that represent a risk of electrocution that can result in serious injury
or death if they are not observed are marked with this warning
triangle.
2. Qualications
These installation instructions are aimed exclusively at qualied
installers with extensive knowledge in the following areas:
n Health and safety at work and accident prevention regulations
n Working with ladders and scaffolding
n Handling and transporting long, heavy components
n Working with tools and machines
n Attaching fasteners
n Assessing the building fabric
n Commissioning and operating the product
In the absence of any of these qualications, a specialist instal-
lation company must be employed to install the product.
Electrical work:
The permanent electrical installation must be carried out by a
qualied electrician in accordance with statutory and local regula-
tions (VDE 100). The enclosed installation instructions for the electri-
cal devices supplied with the product must be followed.
The unit is to be protected with an upstream
FI circuit breaker in accordance with VDE regulations.
3. Goods receipt
The delivery must be inspected immediately upon receipt for any
damage sustained in transit. In addition, the contents of the ship-
ment must be checked against the delivery note.
4. Transport
The permissible axle loads and the permissible total weight of
the means of transport must not be exceeded. Loading can affect
the vehicle’s handling.
The goods being transported are to be tied down and properly
secured. The metal blind packaging must be kept dry.
Wet packaging may disintegrate, causing accidents. Packaging
opened for the purpose of inspecting incoming goods must be
properly taped up again for further transportation.
After unloading, the metal blind should be transported to the
installation site right-side-up and in the proper installation posi-
tion, so that it will not have to be manoeuvred later in tight spaces.
Attention must be paid to the note on the box indicating position
and side.
5. Lifting with ropes
If the metal blind needs to be lifted to a higher position using
ropes, the metal blind should be
n taken out of the packaging,
n fastened to the hoisting ropes in such a way that it cannot
slip off
n and lifted smoothly in a horizontal position.
The same applies to taking down the metal blind.
6. Installation
Prior to installation, check the load-carrying capacity of the
sub-construction.
It is important to check the structural properties of the glass facade
construction prior to installation. In addition, ensure that the
fastening screws are screwed directly into the supporting structure
and that, in the event of wind, there is no connection to the glazing
bead, as this could result in stress cracks. If this is not feasible, the
installation must not be performed.
If there is any doubt, the manufacturer of the glass facade construc-
tion must be consulted.

Caution:
Supplied without ttings (accessories).
The installer must select ttings that are suitable for the particular
sub-construction.
The installer is solely liable for ensuring that the ttings are suitable
for the respective brickwork and that the installation work is per-
formed properly. The respective installation notes from the manu-
facturer of the glass facade construction must be adhered to!
7. Fasteners
The metal blind fulls the requirements of the wind resistance
class specied in the CE conformity mark (see operating instruc-
tions). When installed, these requirements are only met if:
n The metal blind is installed using the type and number of
brackets recommended by the manufacturer
n The metal blind is suitably mounted to the sub-construction
n The wind resistance class to be achieved depends on the
installation substructure and unit width
n The conditions to be complied with to ensure that the perfor
mance specications are fullled are based on static loads and
do not take account of any dynamic effect of repeatedly
applied loads (turbulence) to which the metal blind and frame
are exposed during actual use. The static pressure can there
fore not be used to determine how to anchor the metal blinds
to the building.
Important safety information for the installation
Maximum permissible wind speed at which the unit can be used
Resistance to wind load
The wind classes dened by DIN EN 13659 do not permit any con-
clusions to be drawn on usability (extending/retracting, intermedi-
ate positions, etc.) under actual wind loads. The manufacturer must
therefore dene the maximum speed above which the metal blind
must be retracted taking into consideration the installation situation
and the blind clearance. This wind speed must be stated in the tech-
nical documentation (e.g. operating instructions). The conditions to
be complied with to ensure that the performance specications are
fullled are based on static loads and do not take account of any
dynamic effect of repeatedly applied loads (turbulence) to which
the metal blind and frame are exposed during actual use. The static
pressure can therefore not be used to determine how to anchor the
metal blinds to the building.
The substructure/distance to the facade/height/corner situation also
has an inuence on the maximum possible wind speed and is not
taken into account in the standard (DIN EN 1932:2013-09 External
blinds and shutters – Resistance to wind loads – Method of testing
and performance criteria) although these factors have a signicant
impact on the product’s resistance to wind loads.
Note regarding applicability
The wind speeds used in the following table only apply with win-
dows closed and not in corner situations. Similarly, the positioning
and number of wind monitors used are of vital importance in se-
lecting the appropriate wind speed for the building in question. In
particular, the building’s geometry and location must be taken into
consideration. For this reason, it is essential to consult the specialist
planner in such situations.
Maximum wind speed at which the unit can be used in m/s
Note:
Please note that the specications on the maximum wind speed at
which the unit can be used relate to installation as intended directly
on the facade. In the case of installation options deviating from the
above, please contact MHZ for the necessary specications.

8. Climbing aids
Climbing aids must not be attached to or leant against the
metal blind. They must be steady and provide adequate grip. Use
only climbing aids with a sufciently high load-bearing capacity.
Only approved climbing aids (ladders) may be used.
9. Fall protection equipment
There is a risk of falling when working at height.
Appropriate fall protection equipment must be used.
10. Electrical connection
The metal blind may only be connected if the
electric drive’s specications match the electricity source (see oper-
ating instructions).
The installation notes included with the electrical components must
be followed.
The unit is to be protected with an upstream
FI circuit breaker in accordance with VDE regulations.
Only cables and connectors with a minimum protection class
of IP 54 should be used to supply power.
11. Intended use
Metal blinds should only be used for the purpose dened for
them in the operating instructions.
Changes, such as attachments and modications, not intended by
the manufacturer may only be carried out with the manufacturer’s
written consent.
Applying additional loads to the metal blind by attaching objects
can result in it becoming damaged or falling down and is therefore
not permitted.
12. Unsupervised operation
When working within the metal blind’s range of motion, the
automatic control must be turned off. There is a risk of crushing or
falling.
In addition, it must be ensured that the unit cannot be unintention-
ally manually operated. For this purpose, the power supply must
be cut, e.g. take out the fuse or disconnect the plug coupling on
the motor.
If the metal blinds are operated by several users, a priority locking
system (externally controlled circuit breaker) must be used, which
makes any retraction and extension of the metal blind impossible.
13. Trial run
The rst time the unit is extended, no one is permitted to be
in the metal blind’s range of motion or underneath it. A visual check
must be made of the fasteners and brackets after the unit has been
extended for the rst time.
For trial runs never use automatic controls or switches from which
the operator has no view of the metal blind (there is a risk of it start-
ing to move unintentionally). The use of a test cable to connect the
motor is recommended.
The installation and adjustment instructions included with the metal
blind from the manufacturers of the motor, switch and control must
be followed.
14. Crush and shear zones, plus sharp-edged parts
To avoid injuries, the end positions of the drive must be adjust-
ed in line with the on-site conditions, where applicable.
There are crush and shear zones between the drop bar, case
covers and around the side guide rails. Caution! Risk of injury!
Limbs and clothing can potentially get caught up, crushed or pulled
in by the unit!
If the metal blind is being tted at a height of less than 2.5 metres
above accessible thoroughfares, the metal blind may only be oper-
ated by a push-button switch within sight of the moving parts.
Electrical controls, radio drives with lock switches, lock switches,
etc. are not permissible in this case.
Any long parts taken off, e.g. covers or guide rails, may have
sharp edges (caution – risk of injury/cuts).

15. Handover
All operating instructions, as well as the installation and adjust-
ment instructions issued by the motor, switch and control manufac-
turers, are to be handed over to the user with appropriate training.
The safety information and information on use relating to the metal
blind must be explained in full. Failure to follow the instructions or
any incorrect operation can cause accidents and damage to the
metal blind.
All instructions are to be kept by the customer for future reference
and must be passed on to the new owner if the metal blind is sold.
Based on knowledge of the particular conditions at the site and
the nished installation, the installation company will tell the user
whether the wind resistance class specied by the manufacturer
has been achieved in the installed condition. If not, the installation
company must document the wind resistance class actually
achieved.
Recommendation:
If you are the installer, have the metal blind’s correct installation and
set-up,the time of installation and details of the acceptance meet-
ing, including that you explained the safety information, conrmed
in writing. The MHZ record of delivery can be used for this purpose
(see p. 23).

Inspect the delivery for any damage
sustained in transit right away. The
contents of the shipment must be
checked against the specications in
the delivery note.
Caution: Supplied without ttings.
The installer must choose ttings suita-
ble for the installation substructure.
Inspection of the sub-construction:
It is important to check the strutural
properties of the glass facade con-
struction prior to installation.
In addition, ensure that the fastening
screws are screwed directly into the
supporting structure and that, in the
event of wind, there is no connection
to the glazing bead, as this could result
in stress cracks.
If there is any doubt, the manufacturer
of the glass facade construction must
be consulted.
Operating note:
A metal blind provides sun protection
– it is not a shield for all forms of weath-
er. If there is a strong wind, ice or snow,
it must be retracted.
If the metal blind is equipped with an
automatic control (e.g. wind and sun
sensor), this must be switched off over
the winter (risk of freezing).
Give the user of the metal blind the
accompanying operating instructions
and explain to them in detail all the
information on metal blind use and
safety.
MHZ metal blinds are largely mainte-
nance-free. If any faults do arise, notify
your specialist retailer.

All further installation steps are performed in the same way
as for a single-unit system.
Care must be taken when installing the mounting brackets
for the guide rail and deection tube on the sword-shaped
bracket in the middle to ensure that the fastening screws on
the left and right are mounted offset to each other (see detail
drawing).
If the holders for the plug couplings are positioned centrally
on the sword-shaped bracket as a mirror image (“head to
head” motor arrangement), they must be installed offset to
one another.
