Safety instructions
Warning about hazards for persons and material that can
be caused by device operation
Keep people away from the travel range of the motors! There is a risk
of fingers becoming crushed or trapped. Motors can protrude into the
room during opening. Before start-up, precautions must be taken to
exclude an injury risk.
To avoid damage caused by wind or rain in the building and to flaps,
dome rooflights etc., we recommend using a wind and rain control unit.
With inward- or outward-opening tilting flaps, the flap must be secured
against tilting downwards after the motor has been disengaged (e.g. for
window cleaning).
We recommend the use of scissor-type safety latches here with an
appropriate opening width.
Assembly note
Attention!
Warning about hazards for persons and material caused by
incorrect handling
Assembly and start-up must be carried out by authorised and qualified
specialist staff only! Compliance with the respective locally applicable
assembly and installation regulations and provisions is mandatory.
The motor swivels about its fastening point during opening and closing.
This swivel range must be free of obstacles. Otherwise the motor and
suspension can become damaged.
Any fastenings required must be dimensioned to match the structure.
Tandem or synchronous motors can be used for very wide or heavy
flaps, dome rooflights, etc.
Make sure the load is distributed evenly across all motors. The different
pressure and tensile forces to be transmitted or the different general
fastening conditions must be taken into account. All fastening and
clamping screws must be tightened.
Installation is only permitted in dry and moisture-protected rooms.
Following the completion of the assembly and electrical installation,
it must be checked whether the flaps, dome rooflights etc. can be
opened and closed properly. No liability will be accepted if installation
instructions and circuit diagrams are disregarded or in the case of
operating errors.
The motor must be disconnected from the power supply before any
disassembly.

Installation
Attention!
Danger to persons and life caused by electric voltage and
current
Cable laying and electrical connection work must only be performed by
authorised and qualified electricians.
The installation of the connection cables and wiring must be carried out
in accordance with the valid regulations and standards.
During connection of the motor, ensure that there is no voltage present
at the connection terminals!
Before connection, the voltage available must always be compared with
the operating voltage of the motor. Incorrect supply voltage can lead to
destruction of the motor! The connection cables must not be subjected
to tensile load, twisted, crushed, bent or sheared.
Execute the cable lengths and cable cross-sections in accordance with
the technical specifications depending on current consumption.
If necessary, determine cable types with the local acceptance authori-
ties.
Maintenance and cleaning
All motors that are used in smoke and heat exhaust systems have to be
serviced, checked and repaired if necessary once every year. A main-
tenance contract is advisable. Only original spare parts must be used.
Repair work is carried out exclusively by VELUX Commercial. Defective
motors must only be repaired in our factory.
Opening the motor is not permissible.
In the event of non-compliance, the warranty shall become null and
void.
Junction boxes must be accessible for maintenance work.
Use a dry, soft cloth to wipe off any soiling. Do not use any cleaning
agents or solvents.
Check the motor, fittings, connection cables and all operating elements
for damage.
Disposal
According to the European Directive, electrical appliances that are no
longer usable must be collected separately and recycled in an environ-
mentally sound manner.
The product must not be disposed of with household waste.
Packaging and accessories must be recycled in an environmentally
sound manner.
