3.
Select the correct type of bracket
(Fig. 13).
4.
Cut self-adhesive drilling template at dashed green line. Attach the grey part to the
closed window sash aligned with centre line “X“ and flush with edge of the frame.
Attach the grey-white part of the template to the frame, also aligned with the cen-
tre line “X” and the white side flush with the sash profile.
In some cases, it might be necessary to place the parts themselves on the window
in order to determine the correct position of the brackets.
5.
Drill holes at the points indicated on the template – bracket blue, chain holder for
top hung sash green
(Fig. 14).
6.
Fasten chain holder for top hung sash (D) to the frame with suitable screws, ensu-
ring that it is correctly aligned.
7.
Connect the locking piece with the chain end by inserting the connecting pin Ø4x32
through both parts.
(Fig. 15).
8.
Plug the two brackets into the the recesses on each side of the drive.
9.
Place the drive on the holes drilled before and fasten with suitable screws.
10.
Verify if the chain end is perfectly aligned with the chain holder. If not, loosen fixing
screws and reposition the brackets.
11.
Carry out the electrical connection as described in chapter 6.
12.
Depending on the particular situation (e.g. small sash height), it might be necessa-
ry to programme a shorter chain stroke
(see chapter 8).
13.
Extend the chain as far as to allow for the connecting pin on the chain end to be
inserted in the slot of the chain holder. Press the locking piece firmly onto the chain
holder until it snaps in audibly. Ensure that the connection is tight.
14.
Verify the correct funtioning in a test run.
6 Electrical connection
6.1 Power supply
Depending on the variant, the drive requires either a voltage of 24 V = (direct current)
or a mains voltage of 230 V ~ (alternating current) 50 Hz.
The 24 V = variant requires a class II mains adapter to transform the supply voltage
(230 V~, 50 Hz or other) to 24 V =; the technical specification of the adapter must cor-
respond to the parameters indicated on the type label.
6.2 Determining the supply cable cross-section for 24 V =
With 24 V =, the cable cross-section must be calculated depending on the cable length.
The following table shows the cable lengths for the connection of one drive.

With 24 V =, the cable cross-section must be calculated depending on the cable length.
6.3 Electrical connection of ELTRAL KS 30/40
The connecting cable of the drive is approx 2 m long. If the distance between drive and
wall switch is longer, the cable must be extended
(chapter 6.2).
The connection is to be carried out according to the following wiring diagrams.
If, after connection, the running direction is contrary to that of the arrows on the
switch, the wires must be inverted (in the case of 230 V ~ wires 2 and 3).
6.4 Electrical connection of ELTRAL KS 30/40 SYNCHRO
The connecting cable of the drive is approx 2,5 m long. If the distance between drive
and wall switch is longer, there is only the possibility to extend the supply line
(chap-
ter 6.2).
ATTENTION:
The white and the red lines must not be extended but connected to the
delivered clamp at a spot within a distance of max. 2,5 m. If the distance between the
drives exceeds 5 m, a faultless transmission of the synchronising signal cannot be gua-
ranteed. Due to the low transforming voltage (5 V), a safe connection with a faultless
electrical contact is of major importance.
IMPORTANT:
Both lines (white and red) must be connected with the chain complete-
ly retracted before the first movement of the synchronised drives. Otherwise commu-
nication problems between the drives might arise.
ATTENTION:
Never apply any voltage (24V / 230V) to the red and white lines.
The connection is to be carried out according to the following wiring diagrams.
