Closed design
BECKER tubular drives with mechanical limit switching must not be connected in parallel. For simultaneous control of several drives use
appropriate BECKER controls.
To control the up and down direction, use external conductor L1.
Other devices or consumption units (lamps, relays, etc.) must not be connected directly to the drive connection cables. For this purpose, the
drives and additional units must be decoupled by relay controls. When installing the drive, an all-pole separation capability from the mains with
at least 3mm contact opening width per pole must be provided (EN 60335).
Attention!
Only use mechanically or electrically locked switching elements with a marked zero position! Protect the electrical connec-
tions against dampness.
BECKER tubular drives are CE certified. These drives comply with the valid EU guidelines and meet EMC regulations.
If the drive is operated with units containing sources of interference, the electrician must ensure suitable interference suppression for the
relevant devices.

you do not wind further than the end limits.

Hand crank for open design
