Assembling the rail
Important instructions for a safe installation.
Observe all assembly instructions.
Incorrect installation can cause serious injury.
The rail is largely preassembled and consists of 3 parts�
The carriage, push rod, release handle, the guide pulley and the lintel
bracket with belt tensioner are in the front part (A)� The seating for the
drive shaft and the sprocket are in the rear part (B)� Lay the front and
rear rail sections one behind the other�
1�
Remove cable ties that secure the belt�
2�
Pull apart the two rail sections completely in order to create a gap
for the middle section (C)� This rail is designed in such a way so as
to easily add the middle section� Slide the 2 connecting pieces (D)
over the seams of the rail sections up to the markings� To secure
the connecting pieces, bend the sheet metal lugs outwards with a
suitable tool�
The assembly of the rail is complete�
10
Tighten the belt
Tighten the belt of the rail until the spring (1) is compressed only
by about half� The spring must compress and be able to bounce during
operation�
11
Fitting rail to the drive
1�
Check if the belt is seated on the gear-wheel� If the belt has slip-
ped off during assembly, relax the belt, lay it and tighten again.
2�
Turn around the rail (1) and completely put on the opener (3) with
the gear side (2)�
3�
Secure the rail on the opener with two mounting brackets (10) and
the screws (21)�
Optional:
To reduce the total overall length by 140 mm the drive can be rotated by
90° as shown in fig.11. This allows access and programming sideways.
Unscrew the switch and mount it to the designated second position�
Remove the rubber plug in order to seal the cable exit� Proceed with
step 3� The change must be made by an authorized electrician�

Centre of the garage door
Eye protection goggles should be worn for overhead work�
All available barriers / locks should be deactivated to avoid damage
to the door�
To avoid serious injuries, remove all cables and chains connected to the
door before installing the door opener� The door opener should be
mounted at a height of at least 2�10 m above the ground�
First, mark the centre line of the door (1)� Draw a line to the ceiling
starting from this point�
For installation on the ceiling, draw another line to the centre of the
ceiling (2) perpendicular to the door starting from this line�
Length approx� 2�80 m�

Mounting header bracket
Note: Mount the rail max� 50mm above the top edge of the door�De-
pending onthe door type, the top edge of the door is lifted by a few cm
during opening�
A. Wall fastening:
Mount header bracket (7) centrally on the vertical centre line (2);
thereby its lower edge lies on the horizontal line� Mark all holes for the
header bracket� Pre-drill holes with 4�5 mm diameter and fasten the
header bracket with wood screws (20)�
Note: In case of mounting on a concrete slab / concrete header, the
provided concrete plugs (22) and screws (20) should be used� Drill hole
size in concrete: 8 mm�
B. Ceiling suspension:
Draw vertical centre line (2) further up to the ceiling and about 200 mm
along the ceiling� Attach header bracket (6) centrally on the vertical
marking up to 150 mm removed from the wall� Mark all holes for the
header bracket� Drill holes with 4�5 mm diameter and fasten the header
bracket with wood screws (20)�
14
Attaching drive to header
It may be necessary to place the drive temporarily higher, so
that the rail does not hit the springs in sectional doors�
The drive must either be well supported (ladder) or held firmly
by a second person. Put drive head on garage floor under the lintel bra-
cket. Lift rail up till the holes of the fixing part and the holes of the lintel
bracket are aligned� Insert screw (14) through the holes and secure with
nut (15)�
