Connection for ELTRAL K35 Synchro - 24 V
The connecting cable of the drive is approx. 2.5 m long. If the distance between drive and wall
switch is more than 2.5 m, only the wires for the power supply can be extended.
The white and red cables must not be extended. They must be connected
ATTENTION
no more than 2.5 m away with the terminal included in the scope of delivery.
If the two drives are more than 5 m apart, there is no guarantee that the synchro-
nisation signal will be transmitted without errors.
The low through-voltage (5 V) makes a secure connection to a fully function-
ing electric contact essential.
NOTE
Important: The two cables (white and red) must be connected before the
synchronised drives are set in motion for the first time with the chain fully
º
inserted. Otherwise there could be communication problems between the
two drives.
