Installing Connectors
1. Remove the sheath of the FOC duplex cable to around 30 cm in length.
2. Install the FOC duplex cable with the associated Simplex connectors.
For detailed assembly instructions for simplex connectors, refer to the"SIMATIC NET
PROFIBUS networks (http://support.automation.siemens.com/WW/view/en/1971286)"
manual.
IMPORTANT: The cut and polished surface of the plastic fiber must be absolutely smooth
and even. Likewise, the plastic jacket must not protrude or be cut unevenly. Every
irregularity causes strong attenuation of the light signal over the fiber-optic cable!
3. Place the Simplex connector in the plug adapter for the IM 153-2 FO and the FOC in the
intended cable routing. Snap the plug adapter closed until you can hear clearly that the side
panels have engaged.
Ensure correct positioning when inserting the connector in the plug adapter: Make sure
the transmitter is always on top and the receiver always on the bottom!
Plug adapter for the IM 153-2 FO
Maximum 30 mm bending radius
Tip: Cut the bottom cable about 10 mm shorter than the top one. That way you´ll achieve a
better cable routing in the cable channel of the IM 153-2 FO.
