Installation and operating instructions
ELTRAL K25 - 24 V | ELTRAL K25 Synchro - 24 V
    Install the motor in a way that it is always accessible.
    Follow the installation drawing which is enclosed in the fi xing set or can be ordered with
us by your responsible distribution company. The drawing contains the dimensions for
the different installation methods according to pro
fi le system.
    All dimensions of the particular installation are the responsibility of the installer;
adjustments may be necessary.
   
Before working on the pro fi les, take note of the following:

Minimum sash width

Minimum sash height

Maximum sash weight

Possible wind and snow loads

Space required on the pro fi le according to the assembly method.
    Check the required minimum distances.
   
Perform a function check. For this purpose, use the proper GU testing and setting
apparatus (see chapter „10 Components and accessories“ on page 25).
8 Electrical installation
DANGER
Risk of electric shock
The electrical installation on site must be performed exclusively by a
quali
fi ed electrician.
    For electrical installation on site, observe the VDE regulations (German
Electrical Engineers Association) and the requirements of the local
electricity supplier.
    Disconnect all components from the mains before carrying out any work
on the installation or the control unit.
DANGER
Risk of damaging the motor beyond repair
The motor requires a 24 V DC connection. Other voltages will destroy the motor.
    Connect the motor accordingly.
    Do not lay the motor connection cable together with a mains cable.
    Never connect 24 V DC drives to a 230 V mains power supply.
Danger of life!
   
Low-voltage lines and power lines must be laid separately.
A two-wire (24 V) connection cable is required for connecting the motor (see chapter „4
Technical data (1 motor)“ on page 20).
    Follow the electrical connection diagram in chapter 14 on page 28.
   
For cable lengths, cable types and cable cross-sections observe the details given in the
connection diagram and under „Technical data“.
    Ensure that the cables are protected against shearing, kinking or twisting. If necessary
use cable ducts.
    Observe the connection assignment, the permitted drive voltage (see type label), the
minimum and maximum power speci
fi cations (see technical data) and the mounting and
installation instructions, and follow them exactly.
The drive must be supplied with a 24 V DC (direct current) voltage.
To convert the mains voltage 230 V ~, 50 Hz or other) into 24 V DC, you need to use a power
supply unit whose technical data corresponds to the information on the drive‘s type label. The
