In the  to be issued by you, point out to the operator that if leads, in 
particular the , are  they could sustain damage. 

When routing the leads make sure that they:

cannot get caught up or trapped,
are not subjected to mechanical loads (i.e. do not pull, apply pressure or bend),
cannot get damaged in any other way.

Make sure that the cables, in particular the , are fastened to the end 
product with adequate  and  and that suitable constructional 
measures prevent the

Emergency release or quick release (option)

In the event of a power failure the drive can be reset via the release mechanism (”ER” or 
“GQR”) in as far as this is fitted. Actuating the release causes the drive to travel back to the 
starting position.

Recommended arrangement of the fittings

(a)

Recommendation

Besides precise alignment of the fittings, we recommend using only one fixing bracket  at 
either side of the fittings. This measure reduces the risk of a misalignment of the two fixing 
brackets which would cause the drive unit to tilt. Fittings with two fixing brackets  can be 
used, but these must be precisely aligned to ensure that the withdrawal force does not 
increase.

Fix the bracket on the one side to utilize the elongated hole. This permits any possible diffe-
rences in length between the fitting dimension of the drive and your application to be appro-
priately adjusted. : the elongated hole (c) should offer at least 2mm play.
