switch, the wires 1 and 2 must be inverted
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.
ATTENTION
The white and red cables
must not be extended
. They must be connected
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
inserted. Otherwise there could be communication problems between the
two drives.
ATTENTION
Never apply voltage at the red and white
cables (24 V / 230 V).
