1. Safety Instructions / Warning - Read before start-up !
• The device may only be used for the intended purpose designed by for the manufacturer.
• The operation manual should be conveniently kept available at all times for each user.
• Unauthorized changes and the use of spare parts and additional devices which have not been
sold or recommended by the manufacturer may cause fire, electric shocks or injuries. Such
unauthorized measures shall exclude any liability by the manufacturer.
• The liability-prescriptions of the manufacturer in the issue valid at the time of purchase are valid
for the device. The manufacturer shall not be held legally responsible for inaccuracies, errors,
or omissions in the manual or automatically set parameters for a device or for an incorrect
application of a device.
• Repairs may only be executed by the manufacturer.
• Installation, operation, and maintenance procedures should only be carried out by qualified
personnel.
• Use of the device and its installation must be in accordance with national legal requirements
and local electrical codes .
• When working on devices the valid safety regulations must be observed.
• Special advice for carriers of cardiac pacemakers:
Although this device doesn't exceed the valid limits for electromagnetic fields you should keep
a minimum distance of 25 cm between the device and your cardiac pacemaker and not stay in
an immediate proximity of the device respective the antenna for some time.

2. Performance Features of the Antenna ANT.U270/270-FCC
The antenna ID ISC.ANT.U270/270 Type –FCC is a circular polarized antenna and can be used at
operating frequencies in the UHF range from 902 MHz – 928MHz.
Due to the circular polarization a reading of Transponder in two orientations is possible.
The antenna is optimized for RFID applications under FCC within the UHF frequency band. In this
frequency band the antenna offers best possible reading performance.

3. Installation
3.1. Mounting Holes
The antenna is designed for wall or fixture mounting. Mounting holes are provided in the housing.
Please note that only these holes should be used when mounting the antenna. An optional mounting set is available to simplify the attachment of the antenna to portal structures or poles and can
be ordered from FEIG ELECTRONIC GmbH.
NOTE:
When fastening the screws it must be ensured that the housing of the antenna is not bend.
Optionally the attachment points should be supported by suitable washers or spacers
(Height 14 mm).
If mounted outside the preferred mounting direction of the antenna is vertical with the connection cable towards ground.
Never mount the antenna in a way that the connection cable is guided to the top.

CAUTION:
Bending radius of the connection cable: 15 mm (static) / 30 mm (dynamic)

3.2. Installation with Mounting Set
A special mounting set provides an easy method of mounting of the antenna at a portal, mast, pole
or bar. After mounting, the antenna can be changed and positioned at three orientations.

3.3. Draining Holes
There are two draining holes inside the housing at the bottom left- and right corner of the antenna.
These holes are used to guide condensing water out of the outer circle of the housing.
NOTE:
The protection class of the antenna is not affected by the draining holes. The blocking that
guarantees the protection class of IP65 is inside the housing.
Water in the outer circle of the housing does not have any impact on the performance of the
antenna.

3.4. Membrane for pressure balance
At the back of the antenna there is a small hole covered with a thin membrane that is used for
pressure balance between the air inside the housing and the air outside the housing. The membrane is water resistant and does not influence the protection class of the antenna.
Figure 4: Membrane for pressure balance
CAUTION:
To keep the full protection class and to prevent performance losses of the antenna it needs
to be ensured that the membrane is not damaged.
