3.1 PREREQUISITES FOR INSTALLATION
A protective grounded contact socket is essential for the power
supply to the device. This must installed in an area 50 cm from
the end of the drive by a trained electrician.
Prepare any tool(s) as well any aids for supporting the drive in
the garage for use (Figure 5).
Check the scope of delivery (Figure 1, 2) and its condition.
Drives which have recognisable packaging damage or recogni-
sable damage to the housing, engine shaft, drive rail, carriages,
push rods, door fittings, power network cable, fastening materi-
als or parts of these components may not be installed on safety
grounds.
3.1.1 CONDITION OF THE DOOR AND THE INS-
TALLATION SITUATION
The garage door drive many only be mounted on garage doors
when in a technically perfect condition: the door should be che-
cked completely–in particular springs, rollers/roller holders,
cables and hinges–for wear and damage. Also check all faste-
nings and screw connections for stability and strength.
Check for ease of movement and weight compensation of the
door leaf:
- manual hand operation of the door must be possible, without
any difficult, over the whole path traversed by the door;
- the door must not start moving autonomously from the end
positions „Door Open“ or „Door Closed“;
- the door must not–if it has been stopped in some arbitrary
intermediate position–run on, open or close autonomously.
Do not use the door anymore and have it repaired by a
qualified engineer before assembling the garage door
drive if there deficits established concerning damage,
wear or ease of movement!
Installation situation:
The minimum clearance between the upper edge of the door
–measured at the highest door running point TLP–and the ga-
rage roof must be at least 35 mm.
Open the door once fully and close it again to determine the
highest door running point TLP.
The drive must be installed behind the TLP if this minimum
clearance is not achieved. The accessory push rod extension is
necessary, the installation depth of the garage door drive ext-
ends according to the push rod extension.
All mechanical locks on the door should be removed
completely.
The upper edge of the door must have an adequately firm upper
edge for fastening the door fittings (recommendation min. of
1 mm). An additional load carrying device should be used (for
sectional door fittings BY 4720) on an unstable door.
The garage door drive is aligned
- horizontally as well as
- above the middle of the door as well as
- in the alignment of the door leaf.
Check that the lintel and ceiling have an adequate stability in
the area planned for fastening of the garage door drive and
have a suitable substrate; prepare suitable fastening material
for use if necessary.
