Becker tubular drives with electronic limit switching can be parallel connected. The maximum switching contact loading of the control device
(timer, relay control, switch, etc.) must be observed.
Use external conductor L1 to control the up and down direction. Other devices or consumption units (lamps, relays, etc.) must not be directly
connected 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! This also applies when drives with
electronic and mechanical limit switching are used in the same system.
The changeover time for changing the running direction must be at least 500ms. Switch and control must not execute simultaneous UP and
DOWN commands.
To operate drives with electronic limit switching, only use control elements (time controls) which do not draw N potential via the drive. The
outputs of the control element must be potential-free in the neutral position.
Protect the electrical connections from damp.
Note
Becker tubular drives bear the CE mark. These drives comply with the valid EU guidelines and meet EMC regulations.
If the drive is to be operated with units which contain sources of interference, the electrician must ensure suitable interfer-
ence suppression for the relevant devices.
