Safety instructions for the electrical connection

There is a risk of fatal electric shock when touching electrical components.
◆ The electrical connection and all work on electrical systems must only be carried
out by a qualified electrician in accordance with the connection instructions in this
manual.
◆ Carry out all installation and connection work only in a de-energised state.
◆ Disconnect all phases of the mains power lead and secure it to prevent any
reconnection.
◆ Check that the system is de-energised.
◆ Prior to connecting, compare the information about voltage/frequency on the
device with that of the local electrical grid operator.
Incorrect wiring may lead to short circuits and destroy the device.
◆ Observe the sequence of connector pin assignments in the wiring diagram on
page 14.
Follow all the electrical connection specifications in the operating manu-
als of your tubular motor.
A defective antenna can cause malfunctions or the failure of the DuoFern
Environmental Sensor.
◆ The antenna lead must not be shortened and damaged.
Information for the parallel connection of several drives
The parallel connection of unsuitable motors can result in damage. Therefore
strictly observe the specifications in the operating manuals of the respective
tubular motors.
◆ The drive of the awning or Venetian blind is connected to the DuoFern Environ-
mental Sensor. Several drives can be connected in parallel. When connecting
motors in parallel, check whether a multiple control relay is prescribed by the
motor manufacturer.
◆ Motors with a power consumption higher than 1000 watts must be operated via a
relay or contactor with a separate mains supply lead.
