SICK RFU63 Series - Preparing for assembly

5.2 Preparing for assembly
5.2.1 Installation requirements
Space requirements
For the typical space requirements, see the:
•
Dimensional drawing of the device variants, see "Device view", page 16 as well as
shape and extent of the reading field of the internal antenna (RFU630-131xx only)
and the external antenna, e.g., RFA630-100, see "Read range", page 19.
•
RFU630-131xx (with internal antenna): The device as well as the external anten‐
nas do not require any physical contact or visual contact with the transponders.
However, align the device and antennas with the reading space.
•
RFU630-041xx (without internal antenna): The external antennas do not require
any physical contact or visual contact with the transponders. However, align the
antennas with the reading space.
Environmental influences
•
Comply with technical data such as the permissible ambient conditions for oper‐
ation (e.g., ambient temperature range), see "Ambient data", page 92 in the
technical data.
•
To avoid condensation, do not expose the device and, if applicable, the any exter‐
nal antenna(s) to rapid temperature changes.
•
To prevent additional external heating of the device, protect the device against
direct and indirect sunlight.
•
For outdoor applications, use suitable weather protection to protect the device
from additional external heating by sunlight.
Suitable weatherproof housings can be found online on the product page of the
device.
•
In order to avoid reflections of the UHF waves and any associated physical phe‐
nomena, make sure if possible that there are no metal surfaces on the side of the
device and on the external antennas in the direction of the transponder.
Possible disturbances of the UHF field caused by reflections of the UHF waves
are:
°
Overreaches
°
“Holes” (destructive interferences)
•
To avoid attenuation of the HF fields due to absorption, exclude the following
between the device or external antennas and transponder:
°
Electrically conductive material, e.g. liquids (water)
°
Persons or animals
Enclosure rating
•
For further information, see "Conditions for specified enclosure rating", page 9
Mounting
•
Fasten the device using the M6 threaded mounting holes provided for this purpose
on the rear of the device. Alternatively, use the M5 threaded mounting holes. Use
the full number of threaded mounting holes of the selected thread size.
•
Mount external antennas according to enclosed documentation.
•
Mount the device and external antennas where they will not be exposed to shocks
or vibration. In mounting situations with strong vibrations, it may be necessary to
provide shock mounts.
