NOTICE! Risk of damage
• Ensure cables are not damaged during installation.
• Ensure that a 12 V or 24 V stabilised power supply line is available for the
drive (rated power 13.2 W) at the point of installation.
• Ensure that the power supply line is suitably arranged and protected.
• Ensure that routings of cables through walls or bulkheads are protected
and insulated by appropriate bushing, grommets or cable conduits.
• Secure all cables to prevent any contact with moving parts.
Proceed as follows:
➤ Decide on the routing of the motor wire (fig. 2, page 3). Each head rail has
a separate cable (except for S1 or SO blind types).
➤ Check the voltage of the blind (see cable label).
➤ Choose a location for the control device (such as switch or remote control)
which must be installed in a visible location.
➤ Connect the blind according to the circuit diagram:
– Manually switched blinds (fig. 7, page 6)
– Remotely controlled blinds (fig. 8, page 6)
– Other control system (fig. 9, page 7)
