Installation
Assembling the drive
Attention
To connect the drive to the driven part, solely mechanical accessory components made by
the drive manufacturer from the current product catalogue may be used.
Prior to mounting, the fitter must ensure that the masonry and the system being motorised are sufficiently robust (drive torque plus
weight of the shading solution).
Caution
Electrical connections may only be carried out by a qualified electrician. Prior to assembly,
the power supply must be disconnected and secured. Please give the enclosed connection
information to the responsible electrical contractor.
These drives cannot be operated with conventional switching elements (switches, timers
and the like).
Calculate the space required at the side (M) by measuring the drive head and wall
bracket. The clear dimension of the box (X) minus the space required at the side (M)
and idler (G) gives the length (L) of the barrel: L=X-M-G.
The space required at the side (M) varies depending on the combination of drive and
wall bracket.
Then mount the wall bracket and idler. Ensure that the barrel is aligned at right angles to the wall and that sufficient axial play is al-
lowed for the mounted system.
Undoing the mounting pin
When pushed in, the mounting pin (2) locks automatically. To undo the mounting pin
(2), push the tab washer (1) upwards and pull out the mounting pin (2).
Assembling the drive adapter with drive adapter safety catch
Put the drive adapter (1) onto the drive shaft of the tubular drive. You can see where
to insert the safety catch (2) from its shape. When inserting the drive adapter safety
catch (2) into the hole (4), make sure that the locking lug (3) engages. You will hear a
click. Check that the safety catch is securely in position by pulling on the drive ad-
apter (1).
